Abstract:	近年來，室內無線通訊的應用已廣泛的引起注意，其中包括了個人行動通訊以及無線區域網路通訊，而IEEE 802.11a由於傳輸速率快，且採用了正交碼分頻多工（Orthogonal Frequency Division Multiplexing：OFDM）可抵抗多重路徑傳播效應，因此將很有可能成為未來無線區域網路的一大主流，因此本論文遂針對其射頻電路做一研究。論文的目的將實做出一操作於5.3GHz U-NII頻帶的射頻放大器模組，期能將升頻器送過來-20dBm的信號放大至23dBm，以符合IEEE 802.11a的發射功率規範，論文中也將會介紹一些實做時所產生的問題，針對其討論並設法改進。在第一章中將會介紹無線區域網路IEEE 802.11a和IEEE 802.11b的一些背景資料。第二章則會介紹一些射頻放大器的基本理論，第三章則會介紹成品、參數量測及實做時所發現的問題並針對其討論，最後則會做總結與未來展望。 Indoor wireless communication（IWC） such as personal communication and wireless local area networks（WLANs） are exploded in recent years. IEEE 802.11a may become one major part in the future wireless local area networks（WLANs） because of its high transmitted speed and the technique of orthogonal frequency division multiplexing which can avoid multipath effects and for this reason, the RF circuit about IEEE 802.11a will be studied in this thesis. The goal of the thesis is to make one RF amplifier module which can operate in the middle U-NII band and amplify the signal power from –20dBm to 23dBm to achieve the specification of the output power of IEEE 802.11a.The problems during making RF amplifier module will be discussed and overcome by some methods. In chapter 1, the background of IEEE 802.11a and IEEE 802.11b.will be introduced. In chapter 2, The design theory of amplifiers will be introduced and in chapter 3, the finial product、measurement of parameters will be shown and the problems of the circuit will also be discussed. Finally it shows the conclusions and future work.
