Annotation: A new hybrid technique for extracting external elements of microwave FET small-signal equivalent circuit (EC) is proposed. The advantage of the technique is a high accuracy of EC element calculation based on measured S-parameters in a single cold mode Vds = Vgs = 0 V, the latter is the simplest for implementation and does not lead to degradation of device parameters.
