In this work, a method for the direct extraction of a field-effect transistor (FET) distributed model is presented. This technique makes use of both pulsed I-V and pulsed S-parameter measurements. Results given are very efficient, especially in terms

Modern remote sensing systems and radars are more and more based on electronically steered antennas. Instead of using one high power tube, each radiating element must contain a full T/R module allowing an individual modulation of amplitude and phase

This paper presents MESFET measurement methods based on pulsed measurements that separate trapping and thermal effects. Derived from these measurements, a model of the trapping effect is determined, as well as a thermal model. The proposed nonlinear

For the first time, a FET nonlinear model, distributed along the gate length and extracted from pulsed I(V) and pulsed S-parameters measurements is presented. This model has led to a better prediction of power saturation mechanism and offers promisin
