ABSTRACT:
A system and method for providing distributed amplification of a plurality of input signals is disclosed. The preferred embodiment of the disclosed invention utilizes two signal path matrixes having signal combiners, hybrid combiners, and phase shifters to dissect an input signal for amplification and subsequent recombination. The unique matrixes disclosed provide for the distributed amplification of any number of input signals factorable as a product of prime numbers including an odd prime number factor, therefore reducing the number of linear power amplifiers required where a number of input signals other than a power of two are used.
