ABSTRACT:
A radially combined RF/Microwave amplifier includes an input divider for dividing the input power signal into "N" input signals, and a single matching/combiner circuit configuration for matching an combining the amplified "N" input signals into one combined output power signal P.sub.T. The system utilizes a stripline/microstrip configuration of the matching/combiner circuitry and suspends this circuitry above one surface of an aluminum chill plate. The input stage of the amplifier is disposed on the opposite surface of the chill plate with the transistors connecting the input stage with the output network across the peripheral edge of the chill plate.
