Abstract
A RF dielectric filter comprising a block of dielectric material including top and bottom exterior longitudinal surfaces and side exterior surfaces covered with a layer of conductive material. RF signal input/output pads are located at opposed ends of the block. Each of the RF signal input/output pads comprises a strip of conductive material bridging between the bottom exterior surface and the side exterior surface. A strip or region of dielectric material surrounds all the sides of the elongate strip of conductive material except for one end of the strip of conductive material on the side exterior surface which is in a direct unitary coupling relationship with the remainder of the conductive material on the side exterior surface. In one embodiment, the strip or region of dielectric material is generally U-shaped and can vary in width.
