Phase-switched impedance modulation techniques and related architectures

Abstract

A phase-switched impedance modulation (PSIM) system for use within a tunable matching network is provided herein. The system comprises a primary port configured to receive an RF signal, at least one transformer having a primary side and a secondary side, wherein the primary port is connected to the at least one transformer at the primary side thereof, at least one submodule comprising a plurality of reactive elements coupled to the at least one transformer, a switch connected to each of plurality of reactive elements, and a controller configured to generate control signals for the plurality of switches to modulate an effective reactance seen at the primary port by controlling at least one selected from the group consisting of a duty cycle and a phase of each of the plurality of switches.
