Abstract
The development of an analytical small-signal model for the intrinsic elements of a dual gate GaAs MESFET (DGMESFET) is described. The model is based on splitting the Z-parameters of each FET part analytically without any simplifications or assumptions. The model is extracted directly from the measured three-port S-parameters. No extra measurements are required, thus reducing the lengthy procedures needed to characterize the DGMESFET. Experimental verification of the new model is presented.
