Abstract :
A nonlinear empirical model is here adopted to model the cold-FET behaviour of a GaAs PHEMT, in the framework of a resistive mixer application. The model, purely mathematical and technology independent, is suitably identified in the device operative region of interest and is validated in large-signal conditions by exploiting a measurements setup based on LS-VNA.
