The main objective of this book is to present all the relevant informationrequired for RF and micro-wave power amplifier design includingwell-known and novel theoretical approaches and practical design techniquesas well as to suggest optimum design approaches effectively combininganalytical calculations and computer-aided design. This bookcan also be very useful for lecturing to promote the analytical way ofthinking with practical verification by making a bridge between theoryand practice of RF and microwave engineering. As it often happens, anew result is the well-forgotten old one. Therefore, the demonstrationof not only new results based on new technologies or circuit schematicsis given, but some sufficiently old ideas or approaches are also introduced,that could be very useful in modern practice or could contributeto appearance of new ideas or schematic techniques.

When I started writing the first edition of RF Power Amplifiers for Wireless Communications,some time back in 1997, it seemed that I was roaming a largely uninhabitedlandscape. For reasons still not clear to me there were few, if any, otherbooks dedicated to the subject of RF power amplifiers. Right at the same time, however,hundreds of engineers were being assigned projects to design PAs for wirelesscommunications products. It was not, therefore, especially difficult to be successfulwith a book that was fortuitously at the right place and the right time.

Abstract: With industrial/scientific/medical (ISM) band radio frequency (RF) products, often times users are new to the structure of Maxim's low pin-count transmitters andfully integrated superheterodyne receivers. This tutorial provides simple steps that can be taken to get the best performance out of these transmitters and receivers whileproviding techniques to measure the overall capability of the design.

概览 通过与传统的仪器进行比较，了解软件定义的PXI RF仪器在速度上的优势。如WCDMA测量结果所示，基于多核处理器并行执行的labview测量算法与传统仪器相比可以实现明显的速度提升。 介绍 你在早晨7:00伴着摇滚音乐的声音醒来，收音机闹钟里的RDS接收器提示你正在收听来自Guns N’ Roses 乐队的Welcome to the Jungle。然后，在你品尝咖啡期时，可以在书房通过WLAN接收器来查收邮件。当准备好工作后，你走出家门，使用一个315MHz的FSK发射机来打开车锁。坐到车里，驶上道路，你又可以享受无线电收音机所提供的没有广告的娱乐节目。稍后，你会通过蓝牙耳机会与车内的3G手机建立连接。几分钟内，车载的GPS导航仪可以修正你当前的3D位置，并向你指示路径。GPS接收机传出的声音提示你需要驶入收费公路，同时RFID接收器将自动收取相应的过路费。 RF技术无处不在。即便作为一个普通的消费者，每时每刻都会受其影响，更不要说一个RF测试工程师了。无线设备的成本大幅降低，可以让业余的时间变得更轻松，但是在设计下一代RF自动测试系统时，将会带来更多的挑战。工程项目所面临的降低测试成本的挑战，比以往任何时候都严峻。因此，当前的自动测试系统所关注的焦点在于减少整体的测试时间。

在 PADS2007 中，增加一部分专门针对射频(RF)设计的功能模块，包括前面介绍的通过AutoCAD 的DXF 文件导入，来建立一个特殊形状的器件管脚。下面我们来介绍一下在高速或者高频电路板设计中，如何在PCB 板边，或者高速、高频信号线周围，或者PCB 板上的空余区域添加屏蔽地过孔。我们先来看一下在没有 PADS2007 的RF 设计模块的情况下，是如何手工添加GND 过孔的。
