W-CDMA是第三代行動通訊系統的標準。在本論文中,我們將研製一W-CDMA基地臺接收機的射/中頻電路,包括訊號鏈路、參考頻率合成模組、及與DSP單元間的介面電路。
我們根據3GPP公佈的相關規格來設計並實現以上所述電路。我們使用Ansoft Serenade模擬軟體進行模擬,模擬的結果顯示我們的設計符合標準,而一旦與天線和基頻DSP單元整合,即成為一完整的接收機。本系統依照標準規定,上傳頻帶是1920MHz至1980MHz,頻寬為5MHz,基頻訊號經QPSK調變,而I/Q chip rate為3.84Mcps。頻率合成模組部份,參考頻率解析度達1KHz,足以補償頻率漂移,而且可單以PLL模組達成此要求。
本論文將詳述系統設計的程序、系統架構的考量、系統模擬的結果及其與標準規格之間的比較、系統電路的實現、和實際量測的結果。論文最後也將分享作者在實作中獲得的經驗與心得。

W-CDMA is the standard of the third generation digital mobile telecommunication system. In this thesis, the RF/IF circuits, the reference frequency synthesizing module, and some peripheral circuits of a W-CDMA base station receiver are realized.
We design and accomplish the receiver RF/IF circuits according to the relative 3GPP specifications. The heterodyne structure is adopted, and the frequency resolution is smaller than 1KHz.The simulation and the test result prove that our design conforms to the standards and is a complete system after integration with the baseband unit. The up-link bandwidth allocates from 1920MHz to 1980MHz. The channel spacing is 5MHz, and the frequency resolution is required to be smaller than 1KHz in order to compensate the frequency drift. The baseband signal is modulated by QPSK schemes and the I/Q chip rate is 3.84Mcps. The design procedure, the concerns of the structure, the simulation and the comparison between our system and the standards, and the implementation and the test results are illustrated explicitly and particularly. Some discussion of the test results and some experience are described in this thesis, too.
