Class F design criteria validation through non linear load pull simulation

摘要

In this paper an approach for class F power amplifier design criteria validation is presented. The aim is to validate class F PA design theory, which is provided by theoretical limits used for calculus simplification. The method is based on full nonlinear simulations carried on a nonlinear PHEMT device model. In particular the difference between theoretical and real optima, and the cases in which this occurs, were evidenced. For such validation a dedicated software tool using a linearization technique, were discussed
