摘要：
In this paper, a hybrid continuous inverse class-F high-efficiency power amplifier based on phase shift analysis is proposed. A broadband and high-efficiency microwave power amplifier are designed by adopting load pull, source pull technique, and low-pass filter matching structure. The measured results show that the drain efficiency ranges from 67.5% to 77.8%, the saturated output power ranges from 40.2 to 42.4 dBm, and the saturated power gain ranges from 10.2 to 12.4 dB in the working frequency band from 2 to 3 GHz. The power amplifier proposed in this paper fits the current broadband microwave communication technology and plays an important role in the transmission of high data flow signals by wireless transmitters.
