Abstract :
A compact mixed modes cylindrical planar dielectric resonator filter in rectangular enclosure with excellent spurious free performance is presented. Space coupling between different mode´s dielectric resonators and iris coupling between identical mode´s dielectric resonators are realized in the filters. All couplings are computed by rigorous full wave mode matching technique. A 6-pole elliptic function filter is designed, constructed and tested. Excellent filter frequency response is obtained.<>
