Abstract

A mathematical optimization approach , including scaling properties of FET devices, has been used in order to control strong nonlinear non autonomous MMIC functions. In particular broadband distributed power amplification and balanced multiplication has been studied. Optimum choice of gate length and embedding impedances permits us to obtain the best compromise between the main performance parameters such as broadband gain, return loss etc, and the power behaviour. Good agreement between theoretical and experimental results has been obtained in order to validate the mathematical approach.
