2.88GHz.For the lower mode with C¼0.6pF and the higher mode with C¼5pF,the effects of varying/on CP perform-ance are given in Figures4and5,respectively.The simulation results suggest that an axial ratio of less than2dB can be found when/ranges between10and25 for the lower mode and between12and16 for the higher mode.3.RECONFIGURABLE DESIGN AND EXPERIMENTAL RESULTSAn antenna prototype with electrically switching was realized using a varactor diode(BB837,Siemens Semiconductor Group).For the dc bias(V0)used for controlling the varactor, its positive is connected to the feed line through a RF choke, which is composed of a high-impedance meandered microstrip line and a grounded capacitor of1nF,and the negative is directly linked to the RF ground plane,as shown in Figure1. Figure6exhibits the experimental results when V0is switched between two different values.From the measured results,it can be seen that the frequency with minimum axial ratio is1.83 GHz for the case of V0¼28V and it is2.96GHz for the case of V0¼6V.The CP bandwidths,determined by3dB axial ra-tio,are2.7and3.3%at the lower and higher CP operating fre-quencies,respectively.In addition,Figure6also demonstrates that a return loss of less than10dB is achieved within the two CP bandwidths.Therefore,the antenna can perform the dual-frequency operation with a frequency ratio of about1.6through switching.The radiation patterns at1.83and2.96GHz are measured and their results are plotted in Figure7.Broadside radiation with good CP performance is observed for each operating fre-quency,and the polarization in the plane of z>0is left-handed. The peak gain at1.83GHz is about3.3dBic and it is merely 0.2dB lower than that at2.96GHz.4.CONCLUSIONA design for circularly polarized annular slot antennas with switchable frequency has been presented.Only one diode is required in the reconﬁgurable design.With controlling the dc bias of the diode,the antenna can perform dual-frequency opera-tion with a high frequency ratio.Moreover,the antenna at the two operating frequencies has almost the same radiation pattern, polarization performance,and peak gain.REFERENCES1.Y.K.Jung and B.Lee,Dual-band circularly polarized microstripRFID reader antenna using metamaterial branch-line coupler,IEEE Trans Antennas Propag60(2012),786–791.2.Nasimuddin,Z.N.Chen,and X.Qing,Dual-band circularly-polar-ized S-shaped slotted patch antenna with a small frequency ratio, IEEE Trans Antennas Propag58(2010),2112–2115.3.J.Y.Sze,C.I.G.Hsu,and J.J.Jiao,CPW-fed circular slot antennawith slit back-patch for2.4/5GHz dual-band operation,Electron Lett42(2006),563–564.4.Y.L.Zhao,Y.C.Jiao,G.Zhao,Z.B.Weng,and F.S.Zhang,Anovel polarization reconﬁgurable ring-slot antenna with frequency agility,Microwave Opt Technol Lett51(2009),540–543.5.N.Jin,F.Yang,and Y.Rahmat-Samii,A novel patch antenna withswitchable slot(PASS):dual-frequency operation with reversed cir-cular polarizations,IEEE Trans Antennas Propag54(2006), 1031–1034.6.T.Y.Lee and J.S.Row,Frequency reconﬁgurable circularly polar-ized slot antennas with wide tuning range,Microwave Opt Technol Lett53(2011),1501–1505.V C2013Wiley Periodicals,Inc.DESIGN OF BROADBAND AND HIGH-EFFICIENCY CLASS-E AMPLIFIER WITH pHEMT USING A NOVEL LOW-PASS MICROSTRIP RESONATOR CELLMohsen Hayati1,2and Ali Lotfi11Electrical Engineering Department,Faculty of Engineering,Razi University,Tagh-E-Bostan,Kermanshah-67149,Iran; Corresponding author:mohsen_hayati@2Computational Intelligence Research Centre,Razi University,Tagh-E-Bostan,Kermanshah-67149,IranReceived31August2012ABSTRACT:In this article,a high-efﬁcient class-E ampliﬁer design with low voltage and broadband characteristics using a novel Front Coupled Tapered Compact Microstrip Resonant Cell is presented.The proposed micorstrip resonator is used as the harmonic control network in order to suppress higher order harmonics,which obtained the optimized impedance matching for the fundamental and harmonics.The class-E ampliﬁer is realized from0.7to1.8GHz,and obtained the power added efﬁciency of72.5–77.5%.The maximum value of Power added efﬁciency(PAE)is79.7%with11-dBm input power at1.5GHz.

efficiency;zero voltage switching;zero voltage derivative switching1.INTRODUCTIONThe modern wireless communication systems need to consume the power supply.The main factor in reducing the consumption of the power supply is designing a low-voltage and high-efﬁ-ciency power ampliﬁer[1].The switch mode power ampliﬁer is an efﬁcient way for solving the efﬁciency problem.The class-E power ampliﬁer is a kind of the switch mode power ampliﬁer that the transistor acts as a switch.The class-E power ampliﬁer is tuned by a shunt capacitance.This type of the power ampliﬁer obtained100%drain efﬁciency theoretically[2].The class-E ampliﬁer’s response conditions are zero voltage switching (ZVS)and zero voltage derivative switching(ZVDS),which lead to zero power loss in the transistor.Therefore,a high-efﬁ-ciency power ampliﬁer is obtained[3].The shunt capacitance in the class-E power ampliﬁer has a main roll for achieving the class-E conditions[4].The power loss in the lower frequency can be neglected,but by increasing the operation frequency,the power dissipation is increased and the ideal operation of the class-E power ampliﬁer will be missed.The antiphase of the voltage and current wave-forms throughout the signal period,obtain the class-E power ampliﬁer with the maximum efﬁciency[5].This purpose can be achieved using a wave shaping network.The conventional class-E power ampliﬁer load resistance is very much lower than the transistor ON-resistance.This effect leads to efﬁciency degrada-tion and a narrowband load matching network[6].Furthermore, the transistor parasitic resistance for both the switch on-state and parasitic inductance leads to efﬁciency degradation in the radio frequency(RF)and microwave applications[7,8].The optimum operation of the class-E power ampliﬁer and the solution to the mentioned drawbacks can be obtained using two main methods:namely active device selection and circuit conﬁguration[9].The class-E ampliﬁer has various conﬁgura-tions such as the cascade[10]and push–pull[11].The cascade class-E conﬁgurations can double the maximum permissible drain voltage,and the push–pull class-E conﬁguration increases the output power and decrease the harmonic distortion with high efﬁciency.A new topology for the class-E ampliﬁer is proposed as an inverse class-E ampliﬁer,which has inductive reactance [12].The inverse class-E ampliﬁer has higher load resistance and lower peak switch voltage in comparison with the class-E ampliﬁer.Also,because of the abruption of the device output inductances,the value of the inductance in the load network is decreased.However,the inverse class-E ampliﬁer can be used only for the small to medium power applications.Therefore,to solve this drawback,the power combining methods have been used[13].Although,this method results in obtaining the inverse class-E ampliﬁer for higher power application,but the circuit conﬁguration and the design procedure are complicated with the circuit size increment because of using two power ampliﬁer circuits.The class-E power ampliﬁer is a high-efﬁciency power am-pliﬁer for the microwave application,which is implemented using the transmission line as the harmonic control network at the output of the ampliﬁer circuit[14].Furthermore,instead of the RF choke(RFC)a section of the transmission line is used.The transmission line has been used in the class-E power ampliﬁer using LDMOS[15],GaN HEMT[16–19],SiC MES-FET[20],and LDMOSFET[21]as the harmonic control net-work increasingly,because of the simplicity of its structure and high rejection of harmonics.Therefore,the class-E ampliﬁer conﬁguration and operation are the best candidates for the design of the ampliﬁer for the modern microwave communica-tion systems[22,23].Consequently,designing of the load network as the harmonic control network for suppression of harmonics in order to obtain a high-efﬁciency power ampliﬁer is the main challenge of the switch mode power ampliﬁers.The designing of the class-E power ampliﬁers using various microstrip structures has been proposed such as a defected ground structure[24],an asymmet-rical spur-line[25],and composite right/left-handed transmission lines[26].The narrowband load network and low efﬁciency remain as the main challenge to the class-E power ampliﬁer using the conventional microstrip transmission line[27].A compact microstrip resonant cell(CMRC)is a one-dimen-sional photonic band gap incorporating the microstrip transmis-sion line,which is,ﬁrst,proposed in[28].The CMRC structure exhibits high rejection of the harmonics with the compact circuit size in comparison with the conventional micorstrip transmission lines.Therefore,it is used for the linearization and efﬁciency in-crement of the microwave power ampliﬁers[29,30].The appli-cation of the conventional CMRC is limited to obtain a high-ef-ﬁciency switch mode ampliﬁer,as a result of the high insertion loss in the passband and restricted stopband.The front coupled tapered CMRC(FCTCMRC)is proposed in[31]for the implan-tation of a low-passﬁlter with high and wide rejection in the stopband with the compact circuit size in comparison with the conventional CMRC.Therefore,it can be widely used for designing the high-efﬁciency and broadband switch mode power ampliﬁer because of high and wide suppression of harmonics.In this article,the harmonic suppression of the class-E ampli-ﬁer using a novel FCTCMRC as the harmonic controller net-work is explored.A class-E ampliﬁer with higher efﬁciency at a wider bandwidth in comparison with the conventional ampliﬁers is achieved.The proposed class-E power ampliﬁer is designed and simulated for a frequency of1.5GHz using the micorstrip resonator structure.The measurement results of the proposed power ampliﬁer validate our design procedure and simulation results.2.CLASS-E AMPLIFIER FUNDAMENTAL AND DESIGN THEORY2.1.Class-E Ampliﬁer OperationThe basic circuit conﬁguration of the class-E ampliﬁer and switch waveforms are shown in Figures1(a)and1(b),respec-tively.The class-E ampliﬁer consists of the switch device,shunt capacitance,series-tuned load network L-C,and an ideal RFC. The switch-on duty ratio is assumed to be50%in designing the class-E ampliﬁer.This value of the duty ratio leads to optimum operation of the class-E ampliﬁer for obtaining high efﬁciency [32].For an ideal class-E operation,three requirements for the drain voltage and current should be met[2]:1.The rise of the voltage across the transistor at turn-offshould be delayed until the transistor is off.2.The drain voltage should be brought back to zero at thetime of the transistor turn-on.3.The slope of the drain voltage should be zero at the timeof the transistor turn-on.Therefore,the class-E power ampliﬁer is constructed based on two conditions as ZVS and ZVDS.These conditions are as follows:v s hðÞjh¼p¼0;(1)dv s hðÞd hh¼p¼0;(2)where v s(y)is the switch voltage,and y¼x t.The quality fac-tor of the output series resonant circuit is assumed inﬁnite. Therefore,the output current is sinusoidal asi oðhÞ¼I m sinðhþuÞ:(3)In the time interval0y<p,the switch device is in the on-state,therefore,using Kirchhoff’s current law at the switch,we havei sðhÞ¼I

is in the on-state.The reactance for all harmonics is negative and comparable in magnitude to the fundamental fre-quency load resistance.The ideal class-E ampliﬁer requirements are difﬁcult to meet.So,we often only tuned the second and third harmonics to get the suboptimum class-E power ampliﬁer solution.The analysis is performed considering just the output network behavior,thus neglecting input signal required to oper-ate the active device as an ideal switch.The optimal fundamental load by the Fourier-series expan-sion analysis in[7]used for achieving the perfect class-E opera-tion can be determined asZ E;f0¼0:28x C Pe49 :(8)This impedance is inductive.On the other hand,for the ideal operation of the class-E power ampliﬁer the impedances at the higher order harmonics are inﬁniteZ

capacitance should be equal to Eq.(10).The matching network for the class-E power ampli-ﬁer using a low-pass Chebyshev-form impedance transformer is proposed in[7].Therefore,the synthesis of the load network is done using a short circuit,and open circuit stubs instead of lumped capacitors in the load network for unwanted harmonics.2.2.Design of a Class-E Ampliﬁer Using a pHEMTAchieving the optimum load is the main factor to obtain high efﬁciency when designing the class-E power ampliﬁer.On the other hand,the optimum load is varied with the operating fre-quency as in Eq.(8).Therefore,designing of the load network, which can operate in the wide frequency range,is needed for designing the class-E power ampliﬁer with the optimum condi-tions.The maximum operation frequency of the class-E power ampliﬁer is restricted by the shunt capacitance.The shunt capac-itance consists of the transistor output capacitance and the exter-nal capacitance.Thus,the optimum operating frequency of the class-E power ampliﬁer is achieved by selecting a transistor with lower output capacitance.On the other hand,the power loss is caused by ON-resistance of the transistor[33].Therefore, the active device with lower ON-resistance is preferred for designing the high-efﬁciency class-E power ampliﬁer.We selected an ATF-34143pHEMT because of its lower ON-resist-ance and lower shunt parasitic capacitance,which provides lower power dissipation and optimum operation frequency using external capacitance,respectively.The circuit topology of the conventional class-E ampliﬁer is shown in Figure2(a).It is designed using the design procedure,which is presented in[2, 3].The value of elements for an ideal class-E power ampliﬁer is tabulated in Table1.In the design of the class-E power ampli-ﬁer,it is assumed that the value of the DC-feed is inﬁnitive,but in real implementation this value isﬁnite,and we used the half wavelength microstrip transmission line for the DC-feed.In the conventional class-E ampliﬁer,using lumped elements, the second harmonic is located within the pass band.Therefore, the bandwidth is limited to one octave.In order to solve this drawback,one way is designing a multiple matching network for various bands and using switching element.This way leads to complexity of the ampliﬁer circuit and degradation of the efﬁciency.The use of the micorstrip transmission line is a low-cost and simple way for designing the class-E ampliﬁer with wide band and high-efﬁciency characteristics.We used the design proce-dure in Section2.1and designed the matching network for the ampliﬁer as shown in Figure2(b).The values of the transmis-sion lines dimensions are given in Table2.The class-E ampli-ﬁer is designed on RT/Duroid5880,a substrate with dielectric constant of2.2,height of15l l,and loss tangent of0.0009.Figure2Idealized class-E power ampliﬁer:(a)lumped elements and(b)transmission lineTABLE1Element Design for the Nominal Class-E AmplifierC i1(pF)C i2(pF)C

[31],for the ﬁrst time,which is used to synthesize a low-pass ﬁlter with high and wide rejec-tion in the stopband.This microstrip structure exhibits bandstop characteristics and slow wave effects,which are used in the stopband extension and the circuit size reduction,respectively.The schematic and equivalent circuit of the resonator is shown in Figures 3(a)and 3(b),respectively.The proposed FCTCMRC has symmetrical topology.Therefore,the even–odd mode [34]can be used to simplify the analysis as shown in Figures 3(c)and 3(d).Consequently,theresonant condition for the odd-mode in Figure 3(c)is obtained by equating the input admittance Y o in of the proposed resonator to zero yields:Z 112x C 1ÀZ 1tan h 1 ÀZ 2tan h 2Z 1þtan h 12x C 1¼0:(11)Using the similar procedure,the even-mode resonant frequencies areobtained by equating the even admittance Y e in to zero as follows:Z 2tan h 1þZ 1tan h 2¼0:(12)The transmission zeros of the equivalent circuit for the proposed FCTCMRC,which is shown in Figure 3(a),is obtained whenY o in ¼Y ein asZ 2sin 2h 2þZ 1sin 2h 1¼cos 2h 1x C 1:(13)Therefore,the resonator characteristics for tuning transmission zeroes in the stopband can be achieved by the length and width of the tapered cells as shown in Figures 4(a)and 4(b).The pro-posed structure is optimized by an EM-simulator (ADS).The obtained dimensions are as follows:L

.(c)Simulation and measurement results of the proposed harmonic control network.(d)Simulation input impedance of the FCTCMRCThe proposed FCTCMRC is fabricated,and the measurement is performed using an Agilent N5230A Network Analyzer.The simulation and measurement results of the proposed FCTCMRC are shown in Figure 4(c).As it is shown,it has an attenuation level À43and À33.1dB at 3.0and 4.5GHz,respectively.Therefore,the high suppression for the second and third har-monics is obtained.The insertion loss from DC to 2.39GHz is lower than À0.1dB.The simulation of the input impedance of the proposed CMRC for the fundamental and harmonics is shown in Figure 4(d).As it is observed,the harmonic impedan-ces are relatively open in comparison with the fundamental im-pedance.Consequently,it can be used as the matching network with high performance and low circuit complexity.4.CIRCUIT DESIGN AND IMPLEMENTATIONThe highly efﬁcient and compact size class-E ampliﬁer is designed and implemented for a 1.5-GHz band using an ATF-34143pHEMT.The proposed circuit is simulated using an Agi-lent’s Advanced Design System (ADS),and fabricated on an RT/Duroid 5880substrate.The active device is biased at V d ¼3V and V g ¼À0.7V.The FCTCMRC is used as the harmonic control network (HCN)at the output of the active device.The proposed HCN absorbed the parasitic reactance and capacitance of the active device.Therefore,it does not need to any lumped elements in series or parallel with the transistor to compensate the parasitic elements.The circuit schematic diagram of the designed class-E ampliﬁer is shown in Figure 5(a).Moreover,the photograph of the fabricated circuit is shown in Figure 5(b).The RFC is realized using the microstrip transmission line (TLb2)with the quarter wavelength at a frequency of 1.5GHz.The input matching elements consist of two series and parallel open stubs.The dimensions of the tapered cells and transmission lines in the HCN are tuned in order to optimize harmonic termi-nation in the implemented ampliﬁer circuit.The design and implementation of the output matching networks using the FCTCMRC as low-pass topology has been done from 0.7to 1.8GHz.The voltage and current waveforms of the designed class-E ampliﬁer are shown in Figure 5(c).The switch is open for the time interval,0.2–0.4ns and the current through it is near zero.The switch is closed during the time interval 0.6–0.8ns,and the voltage across it is near to zero.The class-E ZVS and ZVDS conditions in the switch turn-off state are obtained.Therefore,the high-efﬁciency class-E ampliﬁer is achieved.The input signal is generated using an Agilent E4433B signal generator,and the measurement is done by an E4440A PSA se-ries spectrum analyzer.The simulated and measured output power and gain for P in ¼11dBm (input power)are shown in Figure 6(a).The maximum output power at 1.5GHz with P in ¼11dBm is 25.3dBm,and the related gain is 14.3dB.The con-ventional class-E ampliﬁer without CMRC has an output power of 18.5dBm and gain of 7.5dB.The class-E ampliﬁer using CMRC has 36.7%output power improvement in comparison with the one without CMRC.The simulation and measurement results for the PAE at P in ¼11dBm (input power)is shown as a function of the operating frequency in Figure 6(b).The highest value of PAE at a fre-quency of 1.5GHz was 79.7%.The value of the PAE is 69.1%for the conventional class-E ampliﬁer without CMRC.There-fore,the proposed class-E ampliﬁer using the novel CMRC has 15.34%PAE improvement in comparison with the one without CMRC.The output power of the conventional class-E ampliﬁer is decreased as the operating frequency is increased.As shown in Figure 6(a),this decrement is considerable when the operating frequency is more than 1.2GHz.Therefore,the conventional class-E ampliﬁer has a drawback for the broadband applications.The designed class-E ampliﬁer has 25.6%circuit size reduction in comparison with the conventional class-E ampliﬁer.5.CONCLUSIONThe class-E ampliﬁer with high efﬁciency and broadband char-acteristics has been designed and implemented.A novel and simple load-matching technique for the low-voltage microwave

Git的Patch功能

Git的Patch功能UNIX世界的软件开发⼤多都是协作式的，因此，Patch（补丁）是⼀个相当重要的东西，因为⼏乎所有的⼤型UNIX项⽬的普通贡献者，都是通过 Patch来提交代码的。

作为最重要的开源项⽬之⼀，Linux，也是这样的。

普通开发者从软件仓库clone下代码，然后写⼊代码，做⼀个Patch，最后⽤E-mail发给Linux Kernel的维护者就好了。

Git最初作为Linux的版本控制⼯具，提供了透明、完整、稳定的Patch功能。

我们先介绍⼀下Patch是什么。

如果⼀个软件有了新版本，我们可以完整地下载新版本的代码进⾏编译安装。

然⽽，像Linux Kernel这样的⼤型项⽬，代码即使压缩，也超过70MB，每次全新下载是有相当⼤的代价的。

然⽽，每次更新变动的代码可能不超过1MB，因此，我们只要能够有两个版本代码的diff的数据，应该就可以以极低的代价更新程序了。

因此，Larry Wall开发了⼀个⼯具：patch。

它可以根据⼀个diff⽂件进⾏版本更新。

不过在git中，我们没有必要直接使⽤diff和patch来做补丁，这样做既危险⼜⿇烦。

git提供了两种简单的patch⽅案。

⼀是⽤git diff⽣成的标准patch，⼆是git format-patch⽣成的Git专⽤Patch。

1.git diff⽣成的标准patch我们可以⾸先⽤git diff制作⼀个patch。

本⽂⽰例的⼯作⽬录⾥最初有⼀个⽂件a，内容是“This is the file a.”，放置在master分⽀中。

为了修改代码，我们⼀般的做法是建⽴⼀个新分⽀：sweetdum@sweetdum-ASUS:~/GitEx$ git branch Fixsweetdum@sweetdum-ASUS:~/GitEx$ git checkout FixSwitched to branch 'Fix'接下来我们在a⽂件⾥⾯追加⼀⾏，然后执⾏git diff。

The BCM20795P1 features secure configuration and patch download for applications involving the management and operation of NFC secure elements. The BCM20795P1 size-optimized architecture is housed in a QFN-34L package that measures4.0 mm × 4.5 mm × 0.9 mm (nominal), and requires minimal external components. This brings the traditional two-chip NFC controller into a single package solution to minimize PCB footprint (see the architecture block diagram in Figure 1 on page 2).The BCM20795P1 is designed for low-power mobile applications. It represents the next generation in NFC technology following the highly successful BCM2079x family of NFC Controllers. The IP base that comprises the BCM20795P1 is the next generation in a family of products that targets the entire NFC ecosystem. Follow-on devices will include multiradio (Bluetooth, Wi-Fi, FM, GPS) combo chips, making the BCM20795P1 an ideal starting point for mobile customers looking for a clear path to cost and board space reduction.The BCM20795P1 leverages the flexibility of multiple secure element interfaces to support two independent Single Wire Protocol (SWP) interfaces in conjunction with two independent host or internal UICC powerswitches enabled for both class B and class C voltage operation and requiring no external support circuitry. This means that, in addition to the platform UICC (SIM card), the BCM20795P1 can interface with a second UICC (SIM card) with both class B and/or class C. Either of the SWP interfaces may be used for alternative SWP-based removable secure elements such as SD cards.The BCM20795P1 incorporates AID routing functionality for support of multiple applications across multiple secure elements and execution environments and also supports application tunneling to secure elements over SWP .The BCM20795P1 is designed to be an integral part of all NFC standards-compliant systems.The BCM20795P1 in conjunction with a suitable secure element and system architecture can enable a mobile handset with the functionality of a mobile point-of-sale (mPOS) terminal to accept contactless payments.ON FI DE NT IA LFO R F A EFeaturesNFC Features•Support for the ISO/IEC 18092, ISO/IEC 21481, ISO/IEC 14443 Types A, B, and B’, Japanese Industrial Standard (JIS) (X) 6319-4, and ISO/IEC 15693 standards •Extended data rates to 848 kbps•Flexibility in antenna size down to very compact sizes due to the introduction of Active Load Modulation (ALM) next generation technology •Reader/Writer (R/W) mode–Support for R/W mode over SWP to UICC/SE for mPOS •Active and Passive Peer (P2P) mode •Tag/Card Emulation mode:–Active load modulation generator for EMVCo PICC performance from a small antenna –Support for host-switched-off Card Emulation mode–Support for powered-by-field operation using minimal residual battery power for register retention only–Support for completely-powered-from-the-field (battery-off) Card Emulation mode •Dual Single Wire Protocol (SWP) interfaces:–SWP_0 with platform Power Management Unit (PMU) or internal power switching to UICC SIM card (class B and class C voltage operation), embedded SE, or removable SE–SWP_1 with platform PMU or internal power switching to UICC SIM card (class B and class C voltage operation), embedded SE or removable SE–Support for application tunnelling to secure elements over SWP •Co-packaged 32 KB EEPROM•Support for AID routing between host and secure elements•Internal low-power oscillator for periodic wake-up and mode switch operation•Low-Power Target Detection mode (LPTD) for extremely low average current consumption “sniff mode”•NFC Forum NFC Controller Interface (NCI) for host interface •Built-in antenna self-test function: –Verifies component assembly–Warning for improperly fitted rear cover antennaON FI DE NT IA LF O R F A EGeneral Features•Integral low dropout (LDO) regulator for direct connection to platform battery•Clock sourced from platform reference frequency input for minimum BOM (or external XTAL option)•ARM Cortex-M0 with 256 KB ROM and 54 KB RAM•Support for UART, SPI, and BSC (I 2C-compatible) host interfaces •Low power consumption in all modes •Minimum hardware size and BOMApplications•Contactless payment •Mobile handsets•Mobile handsets with mPOS•Simplified connectivity between wireless devices •Contactless ticketing •Peer mode transactions •Access control•Smartposter tag reading/writing。

SparkSwitch PRO产品说明书

Instruction ManualDear customer,we are delighted that you have selected the SparkSwitch PRO from Power-Box-Systems.The SparkSwitch PRO is the logical development of the original SparkSwitch, which has been successful in the market since its introduction in 2008. The SparkSwitch PRO combines acknowledged reliability with new telemetry trans-mission options.The SparkSwitch PRO incorporates a genuine bi-directional infra-red connection which physically isolates the receiving system from the ignition circuit, but at the same time sends telemetry information from ignition and engine to the telemetry interface via a light signal. This eliminates the danger of interference or static charge from the ignition circuit reaching the receiver.The ignition switch is ready for immediate use, without any adjustment work. All you have to do is select the appropriate telemetry system using the USB interface adapter or the BlueCom adapter.A two-position switch is required at the transmitter.Please read through these instructions, as they will help you become familiar with your new accessory as speedily as possible.We are confident that you will thoroughly enjoy using the PowerBox SparkSwitch PRO.Specification- Input voltage 4.0 – 13.0 V- Regulated or open output voltage: 5.9 V / battery voltage- Max. output current 2 A, peak 4.5 A- External power-on LED- Power circuits isolated using IRDA light transmission- Two different switching modes- Telemetry function for PowerBox, Jeti, Futaba, Graupner, Multiplex, JR- T elemetry data includes battery voltage, current, consumed capacity, tempera-ture and RPM- Failsafe mode- Stand-by current drain, ignition side: 60 µA- Weight: 16 g2. EXTERNAL CONTROLSThe illustrations below show the essential external elements:to ignition,(PWM signal)Temperature sensor socket Telemetry and data socket3. FIRST STEPS BEFORE USING THE UNIT3.1. CONNECTINGComplete all the electrical connections as shown in the wiring diagram above. The battery should be connected last.For safety reasons the external LED must always be connected. It should be in-stalled in such a position that the external LED is clearly visible to the pilot at all times when the engine is being started.Caution: If the external LED is not installed, the pilot has no way of knowing whether the ignition is switched on or off. This involves unnecessary danger!3.2. INSTALLED POSITIONInstall the SparkSwitch PRO close to the ignition unit. Do not run the ignition pow-er supply cables close to other wiring which is connected to the receiver.3.3. SETTING THE TELEMETRY SYSTEMConnect the PowerBox USB interface adapter or BlueCom adapter to the socket on the ignition switch marked DATA. A battery (max. voltage 8.4 V) must also be connected to the receiver socket. Run the PowerBox Terminal program on your PC, or the Mobile Terminal App on your smartphone, then follow the on-screen instructions.3.4. IGNITION BATTERYAll types of ignition battery can be used: LiPo, Li-Ion and LiFe up to 3S, NiCd or NiMH up to 5S. Take care to maintain correct polarity when connecting the bat-tery, as reversed polarity will ruin the electronics in the SparkSwitch PRO.The unit’s integral regulator basically limits the voltage to 5.9 V, which means that the SparkSwitch PRO is suitable for all battery types such as 4.8 V, 6.0 V. For all other types of ignition unit please disable the integral regulator using PowerBox Terminal.Note: if you wish to use batteries with a voltage higher than 8.4 V, it is essential to disable the 5.9 V voltage regulation circuit, otherwise the integral voltage regula-tor will overheat under load.The ignition battery can be left connected permanently to the SparkSwitch. The current drain when switched off is so low (60 µA) that it will not discharge the battery even over a period of months3.5. DEFINING THE SWITCH CHANNEL AT THE TRANSMITTERNormal mode:Switch position A is programmed to 0% at the transmitter, and is always the “OFF”position.Switch position B is programmed to +100% at thetransmitter, and always switches the SparkSwitch“ON”.If no valid signal is present at the receiver, theSparkSwitch switches itself off. Ideally you shouldprogram the transmitter’s fail-safe function sothat the SparkSwitch cuts the engine if the signalis lost.Safety mode:Switch position A is programmed to 0% at thetransmitter.Switch position B is programmed to -100% at thetransmitter.The switching procedure is as follows: move theswitch from A to B to prepare the SparkSwitch forthe switching process; this alters nothing at theSparkSwitch’s output. The unit’s switched stateonly changes when the switch is moved back tothe A position.This means: if you accidentally operate the switch on the transmitter during a flight, this does not switch off the SparkSwitch. Non-latching transmitter swit-ches are ideal for this mode: pull the switch and release it in order to switch the ignition on; repeat the procedure to switch the ignition off again.If there is a loss of voltage on the receiver side, the SparkSwitch always switches off, and stores the last switched state, i.e. if the signal is restored, the SparkSwitch will either be “ON” or “OFF” according to its previous switched state. This means: if there is intermittent contact in the signal wire, this will not cause the engine to cut.We recommend that you set up fail-safe at the transmitter in such a way that the engine is stopped by the throttle flap.3.6. TELEMETRY SETTINGYou can use either the PowerBox BlueCom adapter or the PowerBox interface adapter to set the telemetry system. Alternatively the Jeti USB lead or the Multip-lex equivalent also work. Please note the following points, which vary according to the telemetry system you select:- PowerBox P² BUSNo adjustments required; the SparkSwitch PRO is simply connected to the socket marked TELE using a patch lead. Servo data and telemetry data are transmitted via the P² BUS. The default switch input channel is channel 12, but you can change the input channel using the telemetry set-up function.The telemetry data are scanned when the system is switched on, and you can then organise the data on the main screen of the transmitter in your preferred arrangement.- Jeti EXThe SparkSwitch PRO must be set to use the Jeti telemetry system. This can be accomplished using the Terminal program or the Jeti USB adapter.Connect the SparkSwitch RX input to the receiver’s switch channel. The recei-ver’s Telemetry input must be set to JETI BOX. Connect the Telemetry output from the SparkSwitch to the receiver’s Telemetry input using the second patch lead. The telemetry data are displayed in the transmitter’s Sensor menu.- Futaba S.BUS 2Once you have selected the Futaba telemetry system, you must connect the Futaba receiver’s S.BUS 2 output to the DATA input of the SparkSwitch. This enables the transmission of servo and telemetry data. The default switch input is channel 12. You will find a detailed, illustrated description of the procedure for setting up a Futaba transmitter for telemetry data in our PowerBox Support Forum.- Graupner HottThe SparkSwitch PRO must be set to the Graupner telemetry system.Connect the RX input on the SparkSwitch to the receiver’s switch channel, then connect the Telemetry output on the SparkSwitch to the receiver’s Telemetry in-put using the second patch lead.The telemetry data are displayed on the transmitter as Engine Modules.- Multiplex M-LinkThe SparkSwitch PRO must be set to the Multiplex telemetry system using either the Terminal program or the Multiplex USB adapter.Connect the RX input on the SparkSwitch to the receiver’s switch channel, then connect the Telemetry output on the SparkSwitch to the receiver’s Telemetry in-put using the second patch lead.The telemetry addresses can be set using the Terminal program.- JR DMSSThe SparkSwitch PRO must be set to the JR telemetry system.Connect the RX input on the SparkSwitchconnect the Telemetry output on theusing the second patch lead.The telemetry data are displayed on the transmitter as F-PACK (V, C, A), Temp. and RPM.3.7. INSTALLING THE TEMPERATURE SENSORThe temperature sensor is attached to the cylinderhead using a ring-screw. This requires a 3.5 mm Øhole to be drilled in one of the engine’s cooling fins.You can then screw the temperature sensor in placeusing a suitable self-tapping screw or M4 machinesupply and Tacho output are linked using a Y-lead.You will find detailed, illustrated instructions on the procedure for connecting the Tacho output in our PowerBox Support Forum.4.

Betty歌词：
Betty I won't make assumptions about Why you switched your homeroom But I think it's cause of me Betty one time I was riding on my skateboard When I passed your house It's like I couldn't breathe You heard the rumors from Inez You can't believe a word she says Most times but this time it was true The worst thing that I ever did Was what I did to you But if I just showed up at your party Would you have me Would you want me Would you tell me to go straight to hell Or lead me to the garden In the garden would you trust me If I told you it was just a summer thing I'm only seventeen I don't know anything But I know I miss you Betty I know where it all went wrong your favorite song Was playing from the far side of the gym I was nowhere to be found I hate the crowds You know that Plus I saw you dance with him You heard the rumors from Inez You can't believe a word she says Most times but this time it was true The worst thing that I ever did Was what I did to you But if I just showed up at your party Would you have me Would you want me Would you tell me to go straight to hell Or lead me to the garden In the garden would you trust me If I told you it was just a summer thing I'm only seventeen I don't know anything But I know I miss you I was walking home on broken cobblestones Just thinking of you
