Class-F power amplifier is a new high-efficiency amplifier. It can be used as the last stage power amplifiers for radar, communication and electronic warfare, and also be an important means of achieving high efficiency, high power and miniaturization for modern electronic devices. The working principle and design method are analyzed, and a high-efficiency class-F power amplifier at S-band is de- signed. Its output power is greater than 10 W, the actual efficiency is up to 75%, and the gain is about 12 dB.
