Embodiments disclosed herein relate to wave guide couplers as well as 3-way, 6-way, and 9-way combiners. The waveguide coupler comprises: a housing having a first outer waveguide branch, a second outer waveguide branch, and an inner waveguide branch; first, second, and third input ports in communication with the first outer, second outer, and the inner waveguide branches respectively; an output port in communication with the inner waveguide branch; a first wall separating the first outer waveguide branch and the inner waveguide branch, the first wall having a first iris; a second wall separating the second outer waveguide branch and the inner waveguide branch, the second wall having a second iris; a first tapered section in the first outer waveguide branch; and a second tapered section the second outer waveguide branch. Various embodiments of the 3-way, 6-way, and 9-way combiners are implemented using the wave guide coupler.

Waveguide combiner apparatus and method

This invention provides novel combline resonators with multiple conductors and multiple dielectrics for compact filters and multiplexers with improved electric response. The novel combline resonator consists of multi-conductors being made up for the simplest case of an inner metallic post, an intermediate conductor, and an enclosure. This structure provides two resonant modes that can be used for realizing compact microwave filters and multiplexers. Such filters offer the low cost, compact size and ease of manufacturing features of traditional combline resonator filters, with additional size reduction due to the fact that a single physical cavity provides two electrical resonators. In addition, the new cavity inherently introduces a transmission zero in the guard-bands enhancing the filter selectivity.
