平衡放大器的优点

平衡放大器的优点1 综述 (1)2 平衡放大器简介 (1)3 平衡放大器的优点 (2)3.1 回波特性和噪声系数 (2)3.2 刚性系数K (4)3.3 元器件的离散性和温度变化对放大器整体性能的影响 (5)3.4 其他的比较 (6)1平衡放大器由于他的低噪声特性，被广泛用于微波波段的低噪声功率放大。

他比单端放大器有更好的稳定性和输入输出回波损耗。

表1是。

2图1图示了一个平衡放大器的结构。

两个相似的（经过挑选的）单端放大器被并联，两个分支分别称之为102a 和102b。

输入信号105通过一个90º混合功率分路器100均等地分配并馈入两个单端放大器的输入端。

然后，每个放大器输出的放大信号由一个90º混合功率合路器103合成一个信号输出106。

图1：一个平衡放大器的结构图3 平衡放大器的优点举一个例子：一个单端放大器和平衡放大器（他们都使用NE334S01砷化镓场效应管）在3.2 ~3.8 GHz频段的。

其中平衡放大器在每一个分支上使用一个单端放大器。

3.1 回波特性和噪声系数图2画出了一个单端低噪声放大器的原理图，PCB的材料是RO4003,厚度20mil，½ 盎司铜箔。

图2：使用NE334S01砷化镓场效应管的单端低噪声放大器的原理图图3图示了NE334S01砷化镓场效应管具有良好的噪声阻抗。

在这个图中，在3.4 GHz最佳的噪声源阻抗被定位在A点，在史密斯图中，A点远离50欧姆匹配点的中心。

换句话说，如果想得到最低的噪声系数，那回波损耗将很差。

如果设计一个在回波损耗上比较好的放大器，那大约会增加0.5dB的噪声系数。

可以从图3的等效噪声圆NCI 看到。

每个NCI圆表示增加0.25 dB的噪声系数。

在频率3.4GHZ时NE334S01有一个最佳的噪声系数0.35 dB。

图4：NE334S01 FET适宜的噪声阻抗图4图示了单端放大器的测试性能。

为了有0.35 dB的噪声系数，输入回波损耗就低于2 dB图4：使用NE334S01砷化镓场效应管的单端放大器的测试性能图5图示了由2个单端放大器组成的平衡放大器。

PCB 版图注意事项
1． VCC 和 VSS 电源线要单独走线，不能和其它芯片（单片机和 LCD 驱动芯片等）共用电源走线。以免使其它芯片的干扰信号通过电源线引到触摸芯片。
2． CP，CVREG，CSEN 三个电容必须靠近芯片放置。感应线上串联的 CX0~CX3 电阻，靠近芯片放置为宜。 3. 尽量大的铺地面积，可以提高抗干扰性。 4. 感应连线和感应焊盘优先布局。芯片靠近感应焊盘放置，感应连线直接引到感应焊盘（或弹簧焊盘），不同按键的感应连线不需要长度一致。感应连线线宽尽量小。感应连线周围不能走其他电源线和信号线。如果实在不能避免，其他走线要垂直跨过感应连线。感应焊盘之间至少留 5mm 间距，感应焊盘和铺地之间距离大于 1.5mm。

依据输入电压的大小达到控制马达输出扭力的目的;
扭矩控制
扭矩控制方式是通过外部模拟量的输入或直接的地址的赋值来设定电机轴对外的输出转矩的大小;具体表现为例如10V 对应5Nm的话;当外部模拟量设定为5V时电机轴输出为2 5Nm:如果电机轴负载低于2 5Nm时电机正转;外部负载等于2 5Nm时电机不转;大于2 5Nm时电机反转通常在有重力负载情况下产生; 可以通过即时的改变模拟量的设定来改变设定的力矩大小;也可通过通讯方式改变对应的地址的数值来实现; 应用主要在对材质的受力有严格要求的缠绕和放卷的装置中; 例如绕线装置或拉光纤设备;转矩的设定要根据缠绕的半径的变化随时更改以确保材质的受力不会随着缠绕半径的变化而改变;

The sensor is hermetically sealed into a metal housing. The size of the housing is similar to a TO-package with a window opening. The window is equipped with an IR-transmissible filter. An additional temperature reference sensor can be installed in the sensor housing. The thermopile sensor exhibits an almost white noise, comparable to an ohmic resistance. The thermopile output signal is direct proportional to incident radiation power largely independent from the wavelength. The frequency behaviour corresponds to a low pass characteristic.2 GENERAL CHARACTERISTICS2.1 ABSOLUTE MAXIMUM RATINGSParameter Symbol Limits Units Conditions Min Typ Max Ambient Temperature Range-40 100 °C Operation / Storage 2.2 ELECTRICAL PARAMETER2.2.1 ThermopileParameter Symb Limits Units Conditions Min Typ Max Sensistive Area 0.7*0.7 mm 2 Absorber Resistance R TP 50 75 100 k ΩResponsivity S V 55 V/W -,500K,1Hz 1)Time Constant 2)τ 25 ms Noise Voltage V RMS 35 nV/√Hz R.M.S.,25°C Noise Equivalent PowerNEP 0.64 nW/√Hz -,500K,1Hz 1) Detectivity D * 1.1*108 cm √Hz/W -,500K,1Hz 1)TC of Resistance 0 0.02 0.05 %/K TC of Responsivity -0.01 0.02 0.05 %/KTemperatureCoefficient Note 1: The values are defined without filter and optics.Note 2: The time constant can be measured as response to an object temperature jump (low to high or high to low) based on the following equations :Low to High : ττ=− −∆=∆t t e V V 1*max ⇒ −∆=∆e V V 11*maxHigh to Low : ττ=−∆=∆t teV V *max ⇒∆=∆e V V 1*max2.2.2 Temperature Reference Typ Thermistor 100k Ω Parameter Symbol Limits Units Conditions Min Typ Max Resistance R TH 28.5 30 30.9 k Ω At 25°C BETA-Value β 3944 3964 3984 K Defined at 25°C/100°C 2.3 HANDLING REQUIREMENTSStresses above the absolute maximum ratings may cause damages to the device.

The sensor does notrequire any cooling and – dependent on the measurement range – canreach a typical accuracy of ±1 K. For narrow temperature ranges as e.g. inbody temperature measurement, a precision of 0.1 K is possible.PerkinElmer Optoelectronics has developed a series of thermopile typesadapted for various applications. Available standard devices are:! sensors for ear thermometers to sense body temperature,! sensors with focussing optics and signal processing electronics (on circuit board or integrated in sensor housing) for object temperature control in microwave ovens, hair dryers, cookers, etc.,! sensor arrays with integrated multiplexer and amplifier for pattern recognition in position control ine.g. automobiles (airbag safety), room sensing by position and direction control of humans, etc.! sensors with infrared bandpass filters for gas detection by infrared absorption. This subject is cov-ered by a separate article [1].The achievement of a good performance of thermopile devices requires a minimum of knowledge on infrared technology and thermal management of thermoelectric devices. This article therefore aims at the necessary basics for a correct implementation.1 Introduction (2)1.1 Photonic detectors (2)1.2 Pyroelectric sensors (2)1.3 Thermopile sensors (3)2 Thermopiles by modern microsystem technology (4)3 Characteristic figures of thermopiles (5)4 Temperature measurements by thermopiles (7)4.1 Calibrating a thermopile for temperature measurements (8)4.2 Factors disturbing the accuracy (8)4.3 Practice of ambient temperature compensation (9)4.4 On the emission coefficient (10)5 Frequently asked questions (10)6 Literature (12)thermophysica minima : Thermopiles for pyrometry1 IntroductionEvery object emits radiation which is largely controlled by the object’s temperature. For an object that has “no color”, which means, no wavelength is selectively emitted or absorbed, the radiation spectrum is completely determined by the temperature alone. In this case, one speaks of a “black body”. The spectral radiation character-istics of a black body can be theoretically calcu-lated. Figure 1 shows them for selected tempera-tures.101031061091012S p e c i f i c s p e c t r a l e m i s s i o n i n W /(m 2µm s r )Wavelength in µmFigure 1: Spectral radiation characteristics of a “black body” at different temperatures (Planck’s radiation law). It is to be noted that the curves never intersect, which means that the radiation intensity at every wavelength is a strict function of the temperature. By measuring the intensity of the radiation one can there-fore determine the object’s temperature.With rising temperature, the intensity at every wavelength of the radiation spectrum increases as well. This means that one can remotely determine the temperature of an object by measuring its radiated power. Such a measurement can, for example, be carried out by using your eyes. The human eye is sensitive for radiation in the range from 0.38 to 0.75 µm. This region – it is naturally called the “visible spectrum” – is marked in Fig-ure 1. If the temperature of an object exceeds 400 °C (700 K), it will emit a remarkable portion of radiation at the red end of the visible region. It will start to glow in a dark red color, an effect well known from electrically heated stoves. When further increasing the temperature – lets say to 1000 °C (1300 K), the glowing will not only become more intensive, but also its color will change to light red, because there are now green and yellow portions added. Radiation from an object with a temperature of 6000 K will ap-temperature of the sun and our eyes are adapted to “detect” this radiation as white light.1.1 Photonic detectorsIf the measured body has a temperature lower than 400 °C, one needs a radiation detector which is sensitive to a much longer wavelength than those of the visible spectrum. A detector is needed, which is sensitive to the infrared region (also called heat radiation) around 10 µm wave-length. There are different sensors available, which are capable for accurately detecting and measuring heat radiation in the 3 to 20 µm infra-red (IR) wavelength region. The most common IR detectors employed during the past decades are based on semiconductors, in which the inci-dent IR radiation induces a change in electrical conductivity, which can easily be measured and used as the sensing signal for the incident power. Such photonic detector systems offer a great ac-curacy and sensitivity to IR radiation. The needed semiconductors and thermal and electrical sys-tems, though, are very expensive.1.2 Pyroelectric sensorsFor a long time the high cost issue posed severe constraints on the development of IR systems for the consumer market. This could only be over-come by another class of detectors. A type of sensor capable to detect IR radiation with a good accuracy and at the same time being available at low cost are the so-called pyroelectric sensors. Here, the heat radiation collected by the pyroelectric material generates a static voltage signal across the crystalline material. Under constant illumination, however, the signal declines, which makes a periodical refresh necessary. This is usually achieved by aThermal factsThere are people who think that an infrared temperature measurement needs to send out some sort of radiation which may be harmful.Therefore they hesitate to use an ear ther-mometer, for example.It thus has to be emphasized that a radiative temperature measurement is an entirely pas-sive method – it measures only the natural heat which is sent out by every object.usually achieved by a mechanical chopper in front of the detector.Pyroelectric detectors are applicable for mass production. They have found their way into theconsumer market through applications in burglar alarm systems and automatic light switches. Here, the detector senses the IR radiation from approaching persons. In this case, no chopper is needed, because an optics focuses the radiation from the moving persons alternately onto two detector crystals with opposite polarity. This generates a difference signal, which drives a switch or an alarm. The advantage of pyroelectric detectors is in detecting moving objects and at the same time suppressing quasi-static signals as from furnaces and other heat sources, which vary only slowly in time. On the other hand, for static temperature measurements one still needs a rela-tively expensive setup which includes mechanical parts.1.3 ThermopilesensorsRecently, an over 150 year old method to meas-ure infrared radiation is revived: The utilization of thermocouples. A thermocouple consists of two different materials which are connected at one end, while the other two ends are attached to a voltage meter (cf. Figure 2a). If there is a tem-perature difference between the common junction and the voltmeter ends, a so-called thermovoltage is shown by the meter. The magnitude of the voltage is a function of the temperature differ-ence, but also dependent on the nature of the two employed materials.If we now attach an absorber to the junction, and place it into the IR radiation coming from an object, the absorber will collect the incident heat (Figure 2b). We can simply say that the absorber and thus the thermocouple junction will warm up due to the incident radiation. After a short while, the temperature difference between the (warm) junction and the (colder) reference ends will sta-bilize. The thermocouple material in turn con-verts the temperature difference into a voltage shown by the voltmeter. Thus, the voltmeter reading is a direct measure for the object tem-perature. This method is principally simple, does not need any mechanics, and can accurately sense static signals. Like the pyroelectric detectors, a thermopile sensor generates the measurement signal by itself, not requiring any current source.heatradiation(a)(b) Figure 2: Thermocouple principle. (a) Two dissimilar conductors form a thermocouple. A temperature dif-ference over the couple generates an electrical voltage.(b) The needed temperature difference emerges if heat is absorbed by the thermocouple junction and led to a heat sink. The developing voltage is proportional to the amount of flowing heat.Classically, several ten macroscopic wire ther-moelements were connected in series in order to increase the generated voltage and to make the system more sensitive. The materials employed were mostly antimony and bismuth, as they ex-hibit a large thermovoltage. The resulting system was called a thermopile, because it was indeed a pile, made of a large heavy block. Figure 3 shows an original sketch of such an instrument after N. Nobili (1835). Due to the large thermal masses it was very slow in following signal changes. As can be imagined, these instruments were origi-nally only applicable for laboratory work.Figure 3: In series connected thermocouples made of antimony and bismuth (a) form a thermopile (b). After N. Nobili (1835).Nowadays, modern semiconductor technology makes it possible to produce thermopile sensors consisting of hundreds of thermocouples on an area of several square millimeters. Such a sensor is extremely sensitive, shows a very fast response。
