Accurate Nonlinear GaN HEMT Simulations from X- to Ka-Band using a Single ASM-HEMT Model

This paper presents for the first time an investigation of the ASM-HEMT model large-signal accuracy across a wide range of operating frequencies. Comparisons between measured and simulated power sweeps are presented at 10, 20 and 30 GHz. Load-pull measurements and simulations are compared spanning the same frequency range. The large-signal simulations of a single ASM-HEMT model exhibit excellent agreement with all power measurements.
