Abstract :
This paper introduces a method for improving the bandwidth of GaN class-F PAs. The key idea behind this broadband class-F PA lies in the bandpass filter (BPF) used at the input matching network of a conventional class-F PA. Harmonic impedance optimization at the input of the FET is performed in order to design the BPF. Theoretical and experimental results verified the proposed method.
