ABSTRACT:
A power amplifier has an input conditioning circuit. At least first and second amplifiers are in parallel with each other and have inputs and outputs. An input signal is coupled to the inputs of the first and second amplifiers. A multi-input power combiner is provided. The outputs of the first and second parallel amplifiers are combined by the multi-input power combiner to add signals of the outputs constructively.
