Abstract
A hybrid matrix amplifier system that yields balanced thermal loads with minimal input signal constraints includes an input multiport hybrid coupler system having outputs joined to a plurality of amplifiers, and an output multiport hybrid coupler system joined to the outputs of the amplifiers. The input multiport hybrid coupler system, and the output multiport hybrid coupler system, each include n stages where n is an integer equal to or greater than 1, with each stage including 2n-1 couplers. These coupler systems may also include strategically-placed phase shifters. Such systems also include N amplifiers where N is equal to 2n, with N inputs from the outputs of the input multiport hybrid coupler system, and with the outputs of the amplifiers connected as inputs to the output multiport hybrid coupler system. This configuration permits a division of the N amplifiers into two groups that each dissipates substantially the same quantity of heat energy.
