本論文主要分為三部份，第一部份主要是針對現今之數位電視廣播射頻接收機之架構作一討論，選擇適合手持式系統之架構，並進行鏈路規劃與分析，其中包含了本地振盪源之相位雜訊對OFDM系統造成之影響。第二部份為此鏈路各級射頻元件之實作，其中包含了積體電路之選取以及外部匹配電路與測試板佈局之設計，並進行規格參數之實測。第三部份則是將各級電路進行整合測試，包含連續訊號與單載波調制訊號之測試，並與鏈路預算之結果比對。由實測得之，本射頻接收機之靈敏度可達-83dBm、動態範圍超過73dB，且僅消耗345mW之直流功率，大幅減少射頻接收機之功率消耗。此外，本論文所採用之雙次轉頻第二零中頻架構減少了使用之晶片與被動元件數目，且接收鏈路不需使用表面聲波濾波器，大大提高了積體化之程度。

This thesis consisted of three parts. The first part discussed the RF architecture for the digital video broadcasting-handheld (DVB-H) system. The system planning and link budget of the RF receiver are included in this part. The effects of phase noise from local oscillator on the OFDM system are also considered here. The second part introduced the implementation of each stage for the designed receiver link. The measurement results for the entire RF receiver module are discussed in the third part, at which the link budget results are also presented for comparison. The sensitivity of the designed RF receiver module is -83 dBm, the dynamic range is more than 73 dB, and the power consumption is 345 mW. The designed RF receiver adopts the dual conversion with zero second IF architecture reduces the number of ICs, passive components, and the power consumption. In addition, the SAW filter is no longer required in the receiver link, and it is more suitable for the system-on-chip application.
