Abstract

An empirical, purely mathematical electron device model is derived, without introducing any constraint on the physical de­vice structure, under simple assumptions widely verified in practical microwave circuit design. In particular, the model is based on a new approach which greatly simplifies the imple-mentation in commercially available CAD pro-grammes for microwave circuit analysis, with re-spect to previous similar approaches. Ex-perimental results are presented which confirm the validity of the model.
