Abstract :
This paper is an extension of work done previously on the comparison of non-linear MESFET models. The list of models that are compared includes the Curtice quadratic, Curtice cubic, Statz, Materka, and Advanced Materka models to which the Angelov´s model has been added. Furthermore, measurements and model prediction of intermodulation distortion (IMD) are now extended to 12 GHz. The comparison is based on the relative error observed between the measured and simulated DC I-V data, and average error for the model prediction of high frequency gain and IMD. Performance of various models is discussed.
