ABSTRACT:
A resonator/filter adapted for direct surface mounting to the surface of a printed circuit board. The resonator/filter comprises a block of dielectric material including at least one resonator through-hole extending therethrough and respective top, bottom and side surfaces defining respective regions of dielectric material covered with conductive material. The top block surface defines at least a first conductive region. A second conductive region on the bottom surface of the block defines an input/output contact which allows the filter to be mounted on the board with the bottom filter surface seated thereon, thus providing a direct ground contact between the board and the resonator through-hole for improved attenuation performance particularly at higher frequencies. A plurality of transmission line embodiments electrically interconnect the first and second conductive regions.
