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.

Two important Microwave remote sensors are the radar and the radiometer. There have been a number of books written on various aspects of radar, but there have been only a few written on Microwave radiometers, especially on sub- jects of how to design and build radiometer systems. This book, which is the second edition of a book originally published in 1989, attempts to fill this void.

Nature is seldom kind. One of the most appealing uses for radio- telephone systems—communication with people on the move—must over- come radio transmission problems so difficult they challenge the imagina- tion. A Microwave radio signal transmitted between a fixed base station and a moving vehicle in a typical urban environment exhibits extreme variations in both amplitude and apparent frequency.

Microwave radio network design is a subset of activities that constitute the overall transmission network design. Transmission networks are sometimes called transport networks, access networks, or connectivity networks. For many wireless carriers, Microwave is becoming a popu- lar preference over wireline (leased lines) transport for many reasons, especially as Microwave radio equipment costs decrease and installation becomes simpler. Low monthly operating costs can undercut those of typical single (and especially multiple) T1/E1 expenses, proving it to be more economical over the long term—usually two to four years. Network operators also like the fact that they can own and control Microwave radio networks instead of relying on other service providers for network components.

隨著電力電子技術(shù)的迅速發(fā)展，電力電子裝置正在向著高頻化、大容量、小體積的方向發(fā)展，其電磁環(huán)境也變得更為復(fù)雜，隨之帶來(lái)的輻射電磁干擾也日益嚴(yán)重。在電力電子裝置設(shè)計(jì)初期開(kāi)展電磁兼容數(shù)值仿真和預(yù)測(cè)對(duì)解決復(fù)雜的電磁干擾問(wèn)題意義重大。 本文介紹了國(guó)內(nèi)外電力電子裝置電磁兼容的研究現(xiàn)狀。針對(duì)電力電子裝置電磁兼容的復(fù)雜性，討論了使用仿真軟件進(jìn)行電力電子裝置電磁兼容分析的策略，主要面向電源印制電路板(PCB)、控制箱和變流器機(jī)柜全波電磁仿真的具體應(yīng)用進(jìn)行了研究。 首先對(duì)PCB電源板進(jìn)行電磁兼容預(yù)測(cè)。采用軟件Protel99SE和CST微波工作室(R)(CST Microwave STUDIO(R)，簡(jiǎn)稱(chēng)CST MWS(R))相結(jié)合進(jìn)行分析，得到．PCB板的表面電流和電場(chǎng)分布圖。根據(jù)分布圖，分析電源板的輻射特性，提出提高PCB電磁兼容性的優(yōu)化設(shè)計(jì)的設(shè)想，在PCB設(shè)計(jì)過(guò)程中加入對(duì)PCB電磁兼容性分析的場(chǎng)仿真，使PCB的電磁兼容分析有一個(gè)直觀的參照物，有助于指導(dǎo)PCB的布局布線，對(duì)PCB優(yōu)化設(shè)計(jì)，提高產(chǎn)品性能有重要作用。根據(jù)仿真結(jié)果將PCB電源板近似等效成電偶極子模型。 其次應(yīng)用CST MICROSTRIPESTM軟件計(jì)算控制箱的屏蔽效能，并在控制箱插入PCB電源板后進(jìn)行輻射特性分析。 最后應(yīng)用全波電磁仿真軟件CST MWS(R)對(duì)變流器機(jī)柜進(jìn)行電磁輻射干擾瞬態(tài)仿真，分析過(guò)程中考慮到了IGBT的開(kāi)關(guān)尖峰、線纜和易產(chǎn)生干擾的電子元器件以及整個(gè)機(jī)箱機(jī)柜。運(yùn)用線性網(wǎng)絡(luò)理論對(duì)仿真結(jié)果進(jìn)行標(biāo)定，由此提出改進(jìn)措施—采用unit cell和微擾理論設(shè)計(jì)屏蔽網(wǎng)，有效地抑制了電磁輻射。
