Patent ID: 7345534

Claim:
A system for efficient power amplification of an electromagnetic signal, comprising: a switchplexer having at least two switchplexer inputs and a switchplexer output, where the switchplexer is configured to provide communication between a selected switchplexer input and the switchplexer output; at least one interstage matching circuit; at least two amplifier stages, each having an amplifier stage input and an amplifier stage output, where the amplifier stage output of a first one of the amplifier stages is in communication with a first one of the switchplexer inputs via the at least one interstage matching circuit; at least one output matching circuit, each having an output matching circuit input in communication with a second one of the amplifier stage outputs, and an output matching stage output in communication with a second one of the switchplexer inputs; and a control unit configured to control selection of the selected switchplexer input and to selectively activate at least one of the amplifier stages.
