Abstract

Described is a phase-switched tunable impedance matching network (PS-TMN). The PS-TMN has an input that can be coupled to a source and an output that can be coupled to a load. The PS-TMN includes one or more phase-switched reactive elements and a controller. The controller provides a control signal to each of the one or more phase-switched reactive elements. In response to one or more control signals provided thereto, each phase-switched reactive element provides a corresponding selected reactance value.

First claim

We claim:

1 . A phased switched tunable impedance network having an input configured to be coupled to a source and having an output configured to be coupled to a load, the tunable impedance network comprising:
one or more phase-switched reactive elements; a controller configured to provide a respective control signal to each of the one or more phase-switched reactive elements such that, in response to the respective control signal provided thereto, each phase-switched reactive element provides a corresponding selected reactance value.
