ABSTRACT:
A dielectric filter includes a plurality of dielectric blocks, each having a resonator therein, in which both the resonant frequency of each resonator and the degree of coupling between adjacent resonators are independently adjustable. The outer and inner surfaces of each dielectric block are coated with a thin film of a conductive material. Input and output electrodes are formed on the dielectric blocks by disposing a conductive film area on exposed areas of the blocks which are not coated with conductive film. Adjacent dielectric blocks are integrally bonded to one another via a conductive adhesive material and output coupling electrodes on the side surfaces of the dielectric blocks are bonded to input coupling electrodes on the side surfaces of adjacent dielectric blocks.
