ABSTRACT

A coupled resonator diplexer has been designed, fabricated, and tested. The design is based on synthesis of coupling matrix of a 3-port coupled resonator circuit using optimization. Unlike conventional diplexers, the presented diplexer configuration does not include any separate junctions for distribution of energy. The diplexer has been implemented at X-band with waveguide cavity resonators, and its measured response is in good agreement with the simulated response.
