An Empirical PHEMT Model and Its Verification in PCS CDMA System

A new empirical PHEMT model has been developed with emphases on the simplicity and accuracy of the model. The purpose of the work is to use fewer model parameters to describe the device nonlinear performance without losing accuracy. This model has been verified in PCS CDMA system. The results show that the model can predict the nonlinear performance of the PHEMT in PCS CDMA application accurately.
