Patent ID: 8427382

Claim:
A power combiner/divider, comprising: a length of single-conductor closed waveguide aligned along a longitudinal axis and terminated at one end by a conductive end plate, said end plate having a plurality N of holes; a conductive matching plate, said matching plate positioned within the waveguide opposite to and spaced apart from the conductive end plate and spaced apart from inner walls of the waveguide; and a plurality N of dual-conductor coaxial input/output ports, each port having an outer conductor that is electrically and mechanically terminated at said end plate about one said hole and an inner conductor that extends through the associated hole into the waveguide and is electrically and mechanically terminated at the underside of said matching plate, wherein the location and geometry of said conductive matching plate and the physical arrangement of the N input/output ports are configured so that at each one of the input/output ports the sum of a direct reflection of power and an N−1 coupled reflection of power are minimized.
