A comprehensive PHEMT core model for switch applications

Summary form only given, as follows. A non-linear pHEMT core model for switch applications is described. The model combines an accurate CV function below pinch-off and a 2D CV function above pinch-off for charge/capacitance modeling. The model has detailed leakage equations near and beyond pinchoff and a dispersion function covering a wide bias range. The model was verified by comparison with modeled and measured data, including IV/transfer curves, leakages, S-parameters/CV curves and power/harmonics for both on-state and off state.
