数字射频存储器(Digital Radio FreqlJencyr：Memory DRFM)具有对射频信号和微波信号的存储、处理及传输能力，已成为现代雷达系统的重要部件。现代雷达普遍采用了诸如脉冲压缩、相位编码等更为复杂的信号处理技术，DRFM由于具有处理这些相干波形的能力，被越来越广泛地应用于电子对抗领域作为射频频率源。目前，国内外对DRFM ...

Introduce High-Speed Digital System Design.

  Recent advances in low voltage silicon germaniumand BiCMOS processes have allowed the design andproduction of very high speed amplifi ers. Because theprocesses are low voltage, most of the amplifi er designshave incorporated differential inputs and outputs to regainand maximize total outp ...

  The MAX2691 low-noise amplifier (LNA) is designed forGPS L2 applications. Designed in Maxim’s advancedSiGe process, the device achieves high gain andlow noise figure while maximizing the input-referred 1dBcompression point and the 3rd-order intercept point. TheMAX2691 provides a hig ...

Radio Frequency Integrated Circuit Design I enjoyed reading this book for a number of reasons. One reason is that itaddresses high-speed analog design in the context of microwave issues. This isan advanced-level book, which should follow courses in basic circuits andtransmission lines. Most analog i ...

  Speed and accuracy don’t always go hand-in-handin DC/DC converter systems—that is, until now. TheLTC3811 is a dual output, fi xed frequency current modeDC/DC switching regulator controller designed for one oftoday’s most demanding power supply applications: highcurrent, ...

  Avalanche photodiodes (APDs) are widely utilized in laserbased fiberoptic systems to convert optical data intoelectrical form. The APD is usually packaged with a signalconditioning amplifier in a small module. An APD receivermodule and attendant circuitry appears in Figure 1. TheAPD modul ...

针对目前汽车追尾事件频发问题，提出一种防汽车车前和车后追尾的安全装置设计。该设计以高性能、低功耗的8位AVR微处理器ATmega8L为核心，结合霍尔式车速传感器、激光雷达测距装置和MMA7260QT加速度传感器，能够兼顾车前和车后，摒弃以往设计中只考虑车前或车后单一性缺点，尤其适用于高速、夜晚或新手行车。 Abstract: & ...

介绍一种基于C8051单片机的动态心电监护系统。该系统由两部分组成：以C8051F320单片机为核心的数据采集装置和以PC机为平台的分析处理系统。硬件电路功耗低，由单片机自带的USB接口将数据传送给PC机。软件平台采用LabVIEW可视化虚拟仪器系统开发平台，将传统仪器的功能模块集成到计算机中，用户可通过修改虚拟仪器的程序改变 ...
