Abstract

This paper presents a non-linear model of a meander gate p-HEMT for switch design. The model combines a modified Parker-Skellern IV form with a custom charge model to accurately predict large signal performance of meander-gate based switches. Comparison between modeled and measured results of a 0.5 mm gate length SPDT switch shows a accurate prediction of the 2nd and 3rdHarmonic generation at the output.
