A Multi-Dimensional Model Of Passive Mesfets For Use In Non-Linear Microwave Signal Processing, Roger Dorval Jan 1994

A Multi-Dimensional Model Of Passive Mesfets For Use In Non-Linear Microwave Signal Processing, Roger Dorval

Theses

A multi-dimensional model which accurately predicts device non-linearities over frequency and power has been developed for MESFETs used in a passive configuration in microwave signal processing applications.

Historically, MESFETs have been used in linear control applications as passive microwave switches and attenuators. More recently, MESFETs operated as passive elements have been employed as power-sensitive non-linear transfer function generators to produce limiters, phase shifters, and linearizers. These devices offer simplicity, high performance, and the opportunity for application in MMIC technology.

This thesis deals with a mapping of passive MESFET non-linear characteristics, and provides insight into the causes of non-linearity in MESFETs …
