In this paper a 2-D I-V MESFET model coupled with a 3-D thermal model is presented. The thermal dependence of the velocity-electric field expression proposed by Chang et al. (1986), has been considered so as to evaluate the device characteristics and small-signal parameters at the actual channel temperature. The effect of the device self-heating has been included by a coupled electrothermal simulation. The thermal dependence of all the physical parameters involved both in the electric thermal model has been taken into account.
