Harmonically-tuned octave bandwidth 200 W GaN power amplifier


In this paper, the design, implementation, and experimental results of a 200 W high efficiency broadband GaN HEMT power amplifier (PA) are presented. Power combining was used to combine the outputs of two individual octave bandwidth 100 W power amplifiers. Optimum fundamental and harmonic load impedances were obtained using load-pull simulations for the… (More)
