Abstract:
1. A power amplifier assembly, comprising: a first power amplifier including, a first input conditioning circuit, at least first and second amplifiers in parallel with each other and having an input and an output, an input signal coupled to the inputs of the at least the first and second amplifiers, and a first multi-input power combiner, wherein 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; and a second power amplifier including, a second input conditioning circuit, at least first and second amplifiers in parallel with each other and having an input and an output, an input signal coupled to the inputs of the at least the first and second amplifier, a second multi-input power combiner, wherein 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; and wherein the assembly has multiple inputs and each of an input of the multiple inputs has an individual buffer that can be independently controlled.
