Abstract
A high efficiency linear amplifier is disclosed. The amplifier comprises an input module having an input coupled to receive an input signal, a first output configured to provide a first signal component, and a second output configured to provide a second signal component. The amplifier also comprises a switching module having a switch input coupled to receive a switch signal, a first input coupled to the first output of the input module, a second input coupled to the second output of the input module, and at least a first output configured to provide a first composite signal. The amplifier further comprises an amplifier module having at least a first input coupled to the first output of the switching module and at least a first output, wherein the first and second signal components comprise constant envelope phase varying signals having different phase relationships and which correspond to the input signal, and wherein the first composite signal comprises temporally sequenced portions of the first and second signal components.
