A comprehensive nonlinear model of GaAs resistor is developed based on DC, pulse and power measurements. The model accounts for electrical and thermal feathers such as velocity saturation, self-heating and breakdown effects. The resistor nonlinearity is mainly due to the velocity saturation, and enhanced by self-heating effect. The model provides accurate performances in DC, transient and harmonic balance simulations, and is a useful tool for monolithic  microwave integrated circuits (MMICs) development.
