Noise and small-signal distributed model of millimeter-wave FETs

Abstract

A distributed FET model is presented for millimeter-wave frequencies and experimental S-parameters are compared with distributed and lumped model values. Termed the sliced model, this distributed circuit model predicts S-parameters and four noise parameters up to frequency of 40 GHz from microwave noise figure measurements. An example is given that shows good agreement between theoretical data and S-parameters and noise figure measurements up to 26 GHz.<>
