Radial power combiner

Abstract

Power combiners and associated methods of manufacturing are provided. An example power combiner includes a plurality of power input structures each of which defines a waveguide that receives a respective electromagnetic radiation input from a respective power source and a central combining conduit. The central combining conduit receives the respective electromagnetic radiation inputs communicated via respective power input structures and combines the respective electromagnetic radiation inputs into a combined power signal for output via an output port communicably coupled with the central combining conduit. The central combining conduit defines a waveguide structure that is configured to minimize insertion loss between the respective electromagnetic radiation inputs and the combined power signal. The central combining conduit may combine the electromagnetic radiation inputs in the absence of a tuning element and may reduce or substantially prevent back reflection of the electromagnetic radiation inputs received from the plurality of power input structures.
