Design of microwave nonlinear circuits: a simple and efficient approach

A simple and effective study for microwave and millimetre-wave non-linear circuits is shown to be viable with minimum modelling and computing effort, for preliminary circuit design or quick and inexpensive active component evaluation. Such a simple approach is also a useful tool to predict possible instabilities and allows a in-depth knowledge of the non-linear circuit behaviour both in terms of optimum loading and biasing.
