Abstract
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.
