本論文前半段主要是介紹E類功率放大器之工作原理。透過電路模型與模擬，觀察理想與非理想E類功率放大器特性表現。本論文後半段主要是依據E類功率放大器設計原理，完成應用於2.4GHz頻段藍芽系統之E類功率放大器實作。單晶微波積體電路部份，利用全球聯合通信(GCTC)及穩懋(WIN)公司所提供的 GaAs 2μm HBT製程來完成E類功率放大器單晶微波積體電路設計。在偏壓電源為3.3伏特情形下，輸出功率為20dBm，增益分別為23dB與11dB，功率增加效率可達57%與72%。Hybrid模組部份，利用Filtronic公司所生產之GaAs PHEMT電晶體，搭配設計之外部電路後，完成兩級E類功率放大器Hybrid模組。在偏壓電源為3.3伏特情形下，輸出功率為20dBm，增益為25dB，功率增加效率可達75%。由實作結果，在2.4GHz頻段藍芽系統，相較於市面上其他類型之功率放大器，E類功率放大器具有提升功率增加效率之能力，延長通訊系統使用時間。

This thesis consists of two parts. Part 1 introduces the characteristics of Class E power amplifier. Part 2 is focused on the implementation of Class E power amplifier for 2.4GHz Bluetooth applications. The design procedure follows the theory of class E power amplifier, and is implemented in MMICs and modules. For MMICs, the GaAs HBT foundry services are provided by the GCTC Ltd. and WIN Ltd.. Under single supply voltage of 3.3V and the output power of 20dBm, two designed MMICs have gain 23dB and 11dB, and power added efficiency (PAE) 57% and 72%, respectively. For Hybrid modules, RF transistors are provided by the Filtronic Ltd.. Under the same supply voltage of 3.3V, the measured output power, gain, and power added efficiency are 20 dBm, 25dB, and 75% respectively. Compared with the other types of power amplifiers on the market, Class E power amplifier has higher power added efficiency, and thus can increase the using time of communication system.
