Matching Circuit-less Power Amplifier Design for Microwave Wireless Power Transmission Systems

A new power amplifier (PA) design method is proposed that eliminates the output-matching circuit to improve efficiency and is applied to a 2.4 GHz 33 W GaN HEMT PA for microwave wireless power transmission applications. The fabricated PA has a drain efficiency of 82.3% and a power-added efficiency of 78.8%. The design parameters and the performance of the fabricated inverse class- F PA are also discussed analytically.
