Abstract
This paper proposes a novel GaN HEMT non-linear model extraction method from small-signal cold S-parameters and large signal waveform measurements, here demonstrated in simulation. These waveform measurements are taken in simple 50Ω conditions, but will be shown to be suitable for switching-mode power amplifier (PA) designs. Class-F and Continuous Class-F switching modes will be demonstrated with this model and verified by comparison with existing work which uses load-pull measurements to achieve the same results.
