Abstract: of the Invention A dielectric block filter which may be mounted on a printed circuit board or other substrate as a single component is disclosed. The dielectric filter utilizes metallized hole foreshortened resonators in the dielectric block, which employs capacitive coupling between resonators controlled in part by an electrode strip coupled to the conductive material covering the majority of the dielectric block surface. Input and output coupling is accomplished via terminals asymmetrically arranged in a mounting bracket. Mounting tabs on the bracket opposite a recessed area holding the dielectric block secure the filter to the circuit board and provide ground connection for the filter. Two or more filters may be arranged on the circuit board to form a duplexer.

Abstract: A dielectric block filter (501) which may be mounted on a printed circuit board or other substrate as a single component. The dielectric filter utilizes metallized hole foreshortened resonators (529-535) in the dielectric block (501), which employs capacitive coupling between resonators controlled in part by an electrode strip (553-558) coupled to the conductive material covering the majority of the dielectric block (501) surface. Input and output coupling is accomplished via terminals (505-507) asymmetrically arranged in a mounting bracket (503). Mounting tabs (515-523) on the bracket (503) opposite a recessed area holding the dielectric block secure the filter (501) to the circuit board and provide ground connection for the filter. Two or more filters (501) may be arranged on the circuit board to form a duplexer.
