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