Abstract

For the first time, a detailed mathematical model and analysis is presented to understand the effect of a transistor's non-linear drain source capacitor, Cds on the operation of continuous class-F mode power amplifiers. Due to the reactive current generated by the non-linear Cds, the impedance trajectories of a continuous class-F PA deviate significantly from ideal operation. Moreover, the presented analysis shows that the power and efficiency do not stay constant in the entire design space as predicted by the ideal continuous class-F mode theory. In some continuous mode operation areas, the power and efficiency improve from the ideal constant values, whereas in other areas they tend to degrade.
