內(nèi)容簡介

　　“本書內(nèi)容豐富，對標準工程主題的安排令人耳目一新。作者以獨特的視角、敏銳的洞察力、輕松的語言展示了工程和無線電科學的方方面面，甚至對那些了解該領(lǐng)域的人來說，這也是一本非常有用的書?！薄狿aulHorowitz，哈佛大學，TheArtofElectronics的作者之一？？本書介紹了射頻系統(tǒng)的基本概念和關(guān)鍵電路，包括用于所有無線電裝置（從半導體芯片上的無線數(shù)據(jù)收發(fā)機到大功率的廣播發(fā)射機）的基本原理。書中涉及的主題包括濾波器、放大器、振蕩器、匹配網(wǎng)絡、調(diào)制器、低噪聲放大器、鎖相環(huán)、傳輸線和變壓器等。對每一個主題，既強調(diào)重要的物理概念，同時又保持分析的精確性。射頻系統(tǒng)的應用則在通信、無線電和電視廣播、雷達和射電天文學等領(lǐng)域內(nèi)闡述。？？本書包含許多練習，只要具有基本的電子學和電路分析知識，就可做出。對電氣工程專業(yè)的學生來說，這是一本理想的教材，同時對該領(lǐng)域的研究人員和專業(yè)工程師以及那些正轉(zhuǎn)入無線通信領(lǐng)域的人們來說也是一本非常有用的參考書。

作者簡介

　　JonB.Hagen于1972年在康奈爾大學獲得博士學位，曾領(lǐng)導過位于波黎各Arecibo觀測天文臺的電氣工程部，目前是康奈爾大學美國國家天文學和電離層中心的實驗室主任。他在雷達系統(tǒng)設計、信號處理以及微波、射頻、模擬電路和數(shù)字電路設計方面有多年工作經(jīng)驗。
