High efficiency linear amplifier

An amplifier comprising:

• an input module having an input coupled to receive an input signal, a first output configured to provide a first set of signal components, and a second output configured to provide a second set of signal components;
• a switching module comprising a plurality of switches, the switching module having 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 one from the group of a first set of composite signals and a first set of composite signal components;
• and
• an amplifier module having at least a first input coupled to the first output of the switching module and a set of outputs,
• wherein each signal within the first set of signal components and each signal within the second set of signal components is a constant envelope phase varying signal, and
• wherein a given composite signal within the set of composite signals and a given composite signal component within the set of composite signal components comprises a temporal sequence of signal component sub-periods within at least one from the group of the first set of signal components and the second set of signal components.

An amplification method comprising:

• receiving an input signal;
• generating a plurality of constant envelope phase modulated signal components corresponding to the input signal;
• temporally sequencing particular portions of signal components within the plurality of signal components to generate at least one composite signal corresponding to the plurality of signal components;
• and
• amplifying the at least one composite signal.
