In this letter, a novel methodology to achieve output broadband matching is proposed. Based on this methodology, a broadband gallium nitride power amplifier (PA) with input matching and stabilization circuit integrated on-chip is designed. The implemented PA achieves a maximum drain efficiency of 62...
