摘要

效率是微波功率放大器的关键因素，特别是在能量应用方面。本文提出了一种消除输出匹配电路以提高效率的新设计方法。采用该设计方法对一个2.4GHz GaN功率放大器进行了演示。通过消除匹配电路，采用反f类运算，30W功率放大器的漏极效率为82.3%，功率附加效率为78.8%。

2.4GHz High Efficiency GaN Power Amplifier using Matching Circuit Less Design

Efficiency is critical element for microwave power amplifier, especially for energy applications. In this paper, the new design approach to enhance the efficiency which eliminates the output matching circuit is proposed. A 2.4GHz GaN power amplifier is demonstrated using the proposed design method. By eliminating the matching circuit and applying inverse class-F operation, the drain efficiency of 82.3% and power added efficiency of 78.8% are obtained for 30W power amplifier.
