Abstract
The need for both linear and efficient pHEMTs for modern wireless handsets necessitates a thorough understanding of the origins of intermodulation distortion at the device level. For the first time, two-tone time domain simulations of a microwave pHEMT using a quasi-two-dimensional physical device model in a CAD environment are presented. The model fully accounts for device-circuit interaction and is validated experimentally for a two-tone experiment around 5 GHz.
