Abstract
An accurate large-signal GaAs HEMT modeling is very important for microwave and millimeter wave power MMIC amplifier design. This paper presents a complete GaAs HEMT model suitable for ultra-wide band application. The model is realized with an improved drain current (Ids) formulation with self-heating and charge trapping modification. This large-signal GaAs HEMT modeling is validated for a wideband frequency from 12GHz to 40GHz and can predict fundamental output power, gain, and power added efficiency accurately.
