<p>A hybrid matrix amplifier system that yields balanced thermal loads with minimal input signal constraints includes an input multiport hybrid coupler system (15-30) having outputs (31-34) joined to a plurality of amplifiers (35-38), and an output multiport hybrid coupler system (43-58) joined to the outputs (39-42) of the amplifiers (35-38). The input multiport hybrid coupler system (15-34), and the output multiport hybrid coupler system (43-58), each include n stages where n is an integer equal to or greater than 1, with each stage including 2<n-1> couplers (15-18, 43-46). These coupler systems (15-34, 43-58) may also include strategically-placed phase shifters (27, 28, 51, 52). Such systems also include N amplifiers (35-38) where n is equal to 2<n>, with N inputs from the outputs (31-34) of the input multiport hybrid coupler system (15-34), and with the outputs (39-42) of the amplifiers (35-38) connected as inputs to the output multiport hybrid coupler system (43-58). This configuration permits a division of the N amplifiers (35-38) into two groups that each dissipates substantially the same quantity of heat energy. <IMAGE></p> |
