Abstract
A switch matrix for particular use in microwave monolithic integrated circuits has FET-based switch elements with at least a combined total of two gates. Embodiments include the use of single and dual gate FETs. A preferred embodiment includes cascode-coupled FETs in series with inductances between input and output terminals. The input is taken from an artificial transmission line formed of a plurality of series-coupled inductors or from the junctions of series-coupled pairs of mutually coupled inductors.
