Abstract

Conductive patterns (131, 135, 140, 141, 145) a formed onto the dielectric block to connect the resonant holes (130) of the duplexer dielectric filter. A conductive pattern (131) is formed on the surroundings of the resonant holes (130) and connected with the conductive material covering the interior of the holes for applying a load capacitance to the resonators. A second conductive pattern (140) forms a coupling capacitance between adjacent resonators and cross coupling between nonadjacent resonators. A third conductive pattern (141) adjusts the resonant frequency between the resonators, a fourth pattern (135) suppresses the capacitance between the holes and a fifth pattern (145) adjusts the resonant frequency of the transmission resonator.
