RF3404;中文规格书,Datasheet资料

TO39-3 Case•Ideal Front-End Filter for European Wireless Receivers •Low-Loss, Coupled-Resonator Quartz Design •Simple External Impedance Matching •Rugged TO39 Hermetic Package•Complies with Directive 2002/95/EC (RoHS)The RF3404 is a low-loss, compact and economical surface-acoustic-wave (SAW) filter designed to provide front-end selectivity in 433.92MHz receivers. Receiver designs using this filter include superhet with 10.7MHz or 500kHz IF, direct conversion and superregen. Typical applications of these receivers are wireless remote-control and security devices operating in Europe under ETSI I-ETS 300 220.This coupled-resonator filter (CRF) uses selective null placement to provide suppression, typically greater than 40 dB, of the LO and image spurious responses of superhet receivers with 10.7 MHz IF. RFM’s advanced SAW design and fabrication technology is utilized to achieve high performance and very low loss with simple external impedance matching (not included). Quartz construction provides excellent frequency stability over a wide temperature range.433.92 MHzSAW FilterRF3404CAUTION: Electrostatic Sensitive Device. Observe precautions for handling.Notes:1.Unless noted otherwise, all measurements are made with the filter installed in the specified test fixture which is connected to a 50 Ω test system with VSWR ≤ 1.2:1. The test fixture L and C are adjusted for minimum insertion loss at the filter center frequency, f c . Note that insertion loss, bandwidth, and passband shape are dependent on the impedance matching component values and quality. 2.The frequency f c is defined as the midpoint between the 3dB frequencies.3.Where noted, specifications apply over the entire specified operating temperature range.4.The turnover temperature, T O , is the temperature of maximum (or turnover) frequency, f o .

PDA TR34文件中文

医疗保健产品生产和检测用隔离系统的设计和验证PDA 技术报告34号2001年9/10月1.0 引言1.1前言近年来，隔离技术迅速出现，作为一种可供选择的人造环境广泛应用于多种医疗保健产品的生产和检测。

隔离系统的性能特征使其可以很理想的用于无菌产品的制备，以及活性物质的隔离。

其它的应用还有临床准备、无菌散装药品/生物制剂、无菌细胞毒素物质的制备，以及无菌检测。

该技术目前没有权威的应用和验证指导，而且关于“隔离系统”和“阻隔器”的概念严重混淆，这是PDA发布此文件的根本动机。

本文件是由美国PDA、日本PDA、A3P、注射药物协会、和德国代表组成的国际委员会制定的。

本文件可用作指导原则；并不作为强制或暗示的标准。

1.2范围本技术报告给出了在医疗保健产品制造工业的生产、开发、检测中广泛应用隔离技术的基本要求。

本技术报告不仅包括产品的无菌保证，也包括了危险物料的隔离。

术语表（附录A）是本技术报告的一个重要组成部分。

医疗保健行业目前没有一整套关于隔离技术的定义。

委员会认为，为了阐述有用的技术信息，我们必须保证读者在应用该技术报告时没有概念的混淆。

委员会也承认在世界的一些地区，在临床制药设备中经过处理的环境条件都叫做“隔离系统”，这些装置与本文定义的隔离系统有着共同的基本特征，然而，它们与现在医疗保健工业中使用的、用于无菌产品的生产和检测的隔离系统有着显著区别。

本技术报告不适用于不符合本文规定和解释的基本标准的设备。

1.3关键定义建立清晰的划分标准来区分是否是隔离系统对于理解本文至关重要。

PDA建议以下关于隔离系统的定义应被全世界医疗保健行业采纳：隔离系统是密封的或者有微生物过滤系统（高效过滤系统HEPA）提供空气并且可以自净化（1）。

当密闭时，仅使用已净化过的内部表面或使用快速传递通道进行物料传递。

当打开时，仅允许物料通过特定的并已经过设计和验证的开口进行进出传递，以排出污染的传递。

它可被用于无菌操作时隔离活性混合物的或者同时用于灭菌处理和隔离。

Fabricated with a Sipex proprietary BiCMOS process, both products require a fraction of the power of older bipolar designs.THEORY OF OPERATIONThe RS-485 standard is ideal for multi-drop applications or for long-distance interfaces.RS-485 allows up to 32 drivers and 32 receivers to be connected to a data bus, making it an ideal choice for multi-drop applications. Since the cabling can be as long as 4,000 feet, RS-485transceivers are equipped with a wide (-7V to +12V) common mode range to accommodate ground potential differences. Because RS-485is a differential interface, data is virtually immune to noise in the transmission line.DriversThe drivers for both the SP490E and SP491E have differential outputs. The typical voltage output swing with no load will be 0 volts to +5volts. With worst case loading of 54Ω across the differential outputs, the driver can maintain greater than 1.5V voltage levels.The driver of the SP491E has a driver enable control line which is active high. A logic high on DE (pin 4) of the SP491E will enable the differ-ential driver outputs. A logic low on DE (pin 4)of the SP491E will tri-state the driver outputs.The SP490E does not have a driver enable.ReceiversThe receivers for both the SP490E and SP491E have differential inputs with an input sensitivity as low as ±200mV. Input impedance of the receivers is typically 15k Ω (12k Ω minimum).A wide common mode range of -7V to +12V allows for large ground potential differences between systems. The receivers for both the SP490E and SP491E are equipped with the fail-safe feature. Fail-safe guarantees that the receiver output will be in a high state when the input is left unconnected.The receiver of the SP491E has a receiverenable control line which is active low. A logic low on REB (pin 3) of the SP491E will enable the differential receiver. A logic high on REB (pin 3) of the SP491E will tri-state the receiver.ESD ToleranceThe SP490E/SP491E devices incorporate ruggedized ESD cells on all driver output and receiver input pins. The ESD structure is improved over our previous family for more rugged applications and environments sensitive to electro-static discharges and associated transients. The improved ESD tolerance is at least ±15kV without damage nor latch-up.There are different methods of ESD testingapplied:a) MIL-STD-883, Method 3015.7b) IEC1000-4-2 Air-Discharge c) IEC1000-4-2 Direct Contact The Human Body Model has been the generally accepted ESD testing method for semiconductors.This method is also specified in MIL-STD-883,Method 3015.7 for ESD testing. The premise of this ESD test is to simulate the human body’s potential to store electro-static energy and discharge it to an integrated circuit. The simulation is performed by using a test model as shown in Figure 9. This method will test the IC’s capability to withstand an ESD transient during normal handling such as in manufacturing areas where the ICs tend to be handled frequently.The IEC-1000-4-2, formerly IEC801-2, is generally used for testing ESD on equipment and systems. For system manufacturers, they must guarantee a certain amount of ESD protection since the system itself is exposed to the outside environment and human presence. The premise with IEC1000-4-2 is that the system is required to withstand an amount of static electricity when ESD is applied to points and surfaces of theFigure 10. ESD Test Circuit for IEC1000-4-2Figure 11. ESD Test Waveform for IEC1000-4-2t=0nst=30ns0A15A30At ¥i ¥equipment that are accessible to personnel during normal usage. The transceiver IC receives most of the ESD current when the ESD source is applied to the connector pins. The test circuit for IEC1000-4-2 is shown on Figure 10. There are two methods within IEC1000-4-2, the Air Discharge method and the Contact Discharge method.With the Air Discharge Method, an ESD voltage is applied to the equipment under test (EUT)through air. This simulates an electrically chargedperson ready to connect a cable onto the rear of the system only to find an unpleasant zap just before the person touches the back panel. The high energy potential on the person discharges through an arcing path to the rear panel of the system before he or she even touches the system. This energy, whether discharged directly or through air, is predominantly a function of the discharge current rather than the discharge voltage. Variables with an air discharge such as approach speed of the object carrying the ESD potential to the system and humidity will tend to change the discharge current. For example, the rise time of the discharge current varies with the approach speed.The Contact Discharge Method applies the ESD current directly to the EUT. This method was devised to reduce the unpredictability of the ESD arc. The discharge current rise time is constant since the energy is directly transferred without the air-gap arc. In situations such as hand held systems, the ESD charge can be directly discharged to the equipment from a person already holding the equipment. The current is transferred on to the keypad or the serial port of the equipment directly and then travels through the PCB and finally to the IC.The circuit models in Figures 9 and 10 represent the typical ESD testing circuits used for all three methods. The C S is initially charged with the DC power supply when the first switch (SW1) is on. Now that the capacitor is charged, the second switch (SW2) is on while SW1 switches off. The voltage stored in the capacitor is then applied through R S, the current limiting resistor, onto the device under test (DUT). In ESD tests, the SW2 switch is pulsed so that the device under test receives a duration of voltage.For the Human Body Model, the current limiting resistor (RS) and the source capacitor (CS) are 1.5kΩ an 100pF, respectively. For IEC-1000-4-2, the current limiting resistor (RS) and the source capacitor (CS) are 330Ω an 150pF, respectively.The higher CSvalue and lower RSvalue in the IEC1000-4-2 model are more stringent than the Human Body Model. The larger storage capacitor injects a higher voltage to the test point when SW2 is switched on. The lower current limiting resistor increases the current charge onto the test point.Table 1.

Always order by complete part number, e.g., A3134ELT .FEATURESs Superior Temperature Stability s Operation From Unregulated Supply s Open-Collector 25 mA Output s Reverse Battery Protections Activate With Small, Commercially Available Permanent Magnets s Solid-State Reliability s Small Sizes Resistant to Physical StressThis low-hysteresis bipolar Hall-effect switch is an extremely temperature-stable and stress-resistant sensor especially suited for operation over extended temperature ranges to +150°C. Superiorhigh-temperature performance is made possible through a novel Schmitt trigger circuit that maintains operate and release point stability bycompensating for temperature changes in the Hall element. Additionally,internal compensation provides magnetic switch points that become more sensitive with temperature, hence offsetting the usual degradation of the magnetic field with temperature. Its low hysteresis makes this device ideal for detecting small changes in magnetic field strength or for use with inexpensive magnets.The device includes on a single silicon chip a voltage regulator,quadratic Hall-voltage generator, temperature compensation circuit,signal amplifier, Schmitt trigger, and a buffered open-collector output to sink up to 25 mA. The on-board regulator permits operation with supply voltages of 4.5 volts to 24 volts.The first character of the part number suffix determines the device operating temperature range. Suffix ‘E–’ is for -40°C to +85°C, and suffix ‘L–’ is -40°C to +150°C. Two package styles provide a magneti-cally optimized package for most applications. Suffix ‘–LT’ is a minia-ture SOT89/TO-243AA transistor package for surface-mount applica-tions while suffix ‘–UA’ is a three-lead ultra-mini-SIP.Data Sheet 27631.4D3134BIPOLAR HALL-EFFECT SWITCHFOR HIGH-TEMPERATURE OPERATION3134LOW-HYSTERESISBIPOLAR HALL-EFFECT SWITCH FOR HIGH-TEMP.

At this point, the output voltage is V OUT(SAT). When the magnetic field is reduced to below the release point (B RP ) the device output goes high. Note especially that release can occur when the magnetic field is removed but to ensure release, a field reversal is required. The difference in the magnetic operate and release points is called the hysteresis (B hys ) of the device. This built-in hysteresis allows clean switching of the output even in the presence of external mechanical vibration and electrical noise.Powering up the device in the absence of a magnetic field (less than B OP and higher than B RP ) will allow in indeterminate output state.
