    Abstract: GPS接收器可分為:RF端及數位訊號處理端兩部分,而本論文的主題為GPS接收器RF module的設計與製作。 因為GPS衛星所傳送的訊號到達接收機天線時,已相當微弱(訊號必v約-130dBm),所以如何將訊號作適當的放大,並濾除訊號頻帶外的雜訊乃是設計RF module時所要考慮的重要因素。除此之外還必須考慮整個RF module的雜訊指數、各級元件間阻抗的匹配及雜訊干擾等問題。在設計的過程中,除了使用電腦輔助設計軟體先做模擬計算之外,也利用各種量測儀器實際量測校正,以求製作一個穩定精確的RF module。 A GPS receiver has two bases including RF end and digital signal process (DSP) end. The focus of this thesis is to design and fabricate a RF module of GPS receiver。 The GPS satellite signal power is very low (approximately –130 dBm) when it arrived at the antenna. So how to amplify the signal appropriately and filter out the out-of-band signals is important to design a RF module. In addition to these two points, we also consider the noise figure, the impedance matching between individual components and the noise interference. In order to design a stable and precise RF module, we use the computer-aided design software to simulate the design and the measure instruments to adjust the data in the design process.
