HEMT models for large signal circuit simulation

Two new large signal HEMT models have been developed. The models have been implemented in both parameter extraction and circuit simulation software, and validated using an automated load-pull system. Both models show significant improvement in performance prediction capability compared to conventional models available in nonlinear simulation software. The validation procedure makes use of an InP based HEMT operating into both matched and un-matched load states at several power levels along with a uniquely defined nonlinear error metric.<>
