ABSTRACT:
A system for efficient power amplification of an electromagnetic signal includes a switchplexer having at least two inputs and an output. The switchplexer may be configured to provide communication between a selected switchplexer input and the switchplexer output. The system also may include two or more amplifier stages, each having an input and an output, and one or more output matching circuits. Each of the output matching circuits may include an input in communication with one of the amplifier stage outputs, as well as an output in communication with one of the switchplexer inputs. A control unit may be configured to control selection of the selected switchplexer input and to selectively activate at least one of the amplifier stages.
