A method of fabricating a waveguide filter includes forming a monolithic polymeric dielectric core configured for fabricating a dielectric-filled cavity, where the core includes a plurality of spaced-apart depressions; applying a layer of conducting metal to an outer surface of the core to form a metallized core with a conductive metal layer, wherein the metal layer includes port openings at opposite ends of the metallized core, and wherein metallized depressions thereby formed are the ridges of the filter's ridge-waveguide sections; and mounting the metallized core on a supporting carrier. A desired number of such filters can be connected with an electrical-series-type connection among one port of each filter to form a frequency multiplexer having a waveguide manifold.
A method of fabricating a ridge-waveguide filter with a signal input port and a signal output port, comprising:
A method of fabricating a frequency multiplexer, comprising
A method as in 8, wherein the waveguide manifold further comprises a structural element selected from the group consisting of a ridge-waveguide segment, an evanescent-mode-waveguide segment, and a quasi-lumped reactive waveguide component, and combinations thereof.
