CW and Modulated Input Second Harmonic Injection for Efficiency Enhancement in Broadband Power Amplifiers
The second-harmonic input impedance plays a critical role on the performance of GaN power amplifiers. In a recent paper, a drain efficiency enhancement for a continuous-mode power amplifiers was reported to be achieved using active broadband second-harmonic injection at the PA input. In this paper,...
