Abstract :
The objective of this paper is to investigate the non-linear performance of some of the most widely used GaAs MESFET models. DC, AC and intermodulation (IMD) measurements were carried out on 300 μm devices, and equivalent circuit parameters were extracted and optimized. Model predictions of IMD were investigated through several figures of merit: gain, IMD3, IMD5, compression points and intercept points. No clear cut "winner" among the models was observed, but Statz and Advanced Materka have the best overall performance.
