A novel Ku-Band dielectric resonator triplexer based on generalized multiplexer theory

The synthesis, design, manufacturing and measurement of a Ku Band dielectric resonator triplexer is presented. In contrast to classical multiplexer configurations, where channels are disposed either in manifold or connected by means of bifurcations, this new design avoids extra elements, and only resonators and coupling elements are needed to achieve the required transfer function. Coupling matrices obtained by the optimization algorithm are simplified in order to converge towards feasible topologies. For verification purpose, a three 36 MHz-channel multiplexer has been manufactured.
