Abstract

This work proposes the steps to design a high efficiency inverse class F power amplifier (PA). In the first step, the optimal termination conditions for the inverse class F are extracted through load-pull measurement. Afterward, low loss and precisely tunable output matching network was chosen in order to obtain high efficiency of the PA. The fabrication of an inverse class F power amplifier for WiMAX applications at a carrier frequency equal to 2.45 GHz following the described design procedure is carried out and the obtained results demonstrate a measured power added efficiency equal to 71.5% and drain efficiency equal to 74%.
