SYNTHESIS AND DESIGN OF CASCADED TRISECTION DIELECTRIC RESONATOR FILTERS Rafi Hershtigl , Ralph Levy2,Kawthar Zake (CT) ABSTRACT Synthesis of filters having asymmetric insertion loss poles as cross-coupled cascaded trisections (CT) of resonators is presented. The theory is applied to the design and realization of cellular PCS base station dielectric resonator filters with extremely demanding req
