ABSTRACT:
A ceramic filter (10) is shown and described. The filter (10) has a filter body having top (14), bottom (16), and side surfaces (18, 20, 22 and 24) with through holes (26, 28) extending from the top (14) to the bottom surfaces (16) defining resonators. The surfaces are substantially covered with a conductive material defining a metallized layer, with the exception that the top surface (14) is substantially uncoated, and with an additional exception that a portion of a side surface is substantially uncoated in proximity to the top surface (14) and extending at least in proximity to between the resonators (26, 28), defining an unmetallized coupling region for electrically coupling the resonators. The filter (10) also has first and second input-output pads (34, 38) on a side surface for facilitating connection to a circuit board, for example.
