Design of 50-Watt 2-Stage Class-F Power Amplifier for Medical Applications

Abstract

In this work, a high power high efficiency and high gain class-F power amplifier with low harmonic content was designed and simulated by using CGH40010F and CGHV40050F Gallium Nitride transistors and NI AWR Microwave Office for electromedical and radar applications. According to the simulation results, 47.5 dBm output power, 73% efficiency and 22 dB gain values were obtained in the 2.7-2.9 frequency band.
