Design of 70% PAE Class‐F 1.2–1.4 GHz 10 WGaNpower amplifierMMIC

Microwave and Optical Technology Letters, 2022
AbstractThis letter presents a novel design of a Class‐F monolithic microwave integrated circuit (MMIC) power amplifier (PA) operating at L‐band with a power‐added‐efficiency (PAE) better than 70%. The MMIC PA is designed via load/source‐pull techniques to locate the optimal impedances at fundamental and harmonic frequencies on not only output but also
