英文摘要：

Traditional class F RF power amplifier design methods utilize harmonic suppression at the output of the amplifier,where square-like drain voltage and close half-sine drain current waveforms are obtained to improve the efficiency of class F power amplifier.The input harmonic controllable matching network can be added to the novel high efficiency class F amplifier.Meanwhile,both input and output harmonic controllable matching networks are used to obtain the best power-added efficiency.The experimental results were found to be in good agreement with simulated results when a circuit was designed and tested at the S band with the novel load-pull/source-pull simulation-based approach adopted in the circuit design.The measurement results show that the maximum PAE of the PA could achieve 75.4% with 40.3 dBm output power when the input power was 28 dBm.
