Abstract: A dielectric block filter having a self aligning, top and shield is provided. Recesses are formed in at least one side of the block, which recess is dimensioned to accept a mating tab or side of a shield that substantially encloses the top end of the filter. The recess in the block in combination with the appropriately shaped tab produces the overall height of the filter and simplifies manufacturing by eliminating the need to hold or affix the shield to otherwise smooth sides of the block.

Abstract: A ceramic bandpass filter (10) that has transmission zeroes above the passband is accomplished without using the top patterning by a block structure that includes a localized mesa (26) formed at the top end of the block that provides increased capacitive coupling between the open circuits and the resonators (30, 32, and 34). This increased top end capacitance provided by the mesa (26) can provide high end or high side transmission zeroes to the characteristic transfer function of the filter.
