摘要

This paper presents a new class of power amplifier (PA) - Class-iF-1- resolving the highly nonlinear double inflection characteristics in the conventional Class-F-1 PA. It is illustrated that, by properly terminating the second harmonic source impedance Z2S from conventional short-circuit to open-circuit, the double inflection nonlinear gain profile can be mitigate...
