本論文開發實現一半雙工無線電傳輸系統，使其縮小於166公釐x160公釐x10公釐中，並使用數位元件進行控制、調變，使此系統具有多級功率放大及智慧型收發功能。文中詳細講解本無線電系統中之各項組成及設計：微處理器、訊號調變器、綜合擴大器及分波器，同時也說明了如何使用、檢測、安裝本系統。 最後亦對本無線電系統各元件進行性能量測，以及本無線電系統之通訊可靠度測試，再利用系統性能配合前人所做之傳輸距離測試，進行極限距離之推估。 A half-duplex Radio Frequency transceiver is developed by digital module and digital modulation. System case size reduced into 160mm x 166mm x10mm. This thesis describes the design of the compositions of each part in radio system: MCU module, Modulation module, Integrated Amplifier module, and Divider. It also explains how to install, examine, and use this transceiver. Three tests about system performance, reliability and mode switch rate are verified in this paper. It also estimates radio transmission distance by using system ability from the test.
