Abstract
A ceramic bandpass filter (10) with improved input/output isolation can be surface mounted. Input/output pads (18 and 2) through which electrical signals pass are located on one surface of a block of dielectric material (12) to permit use of the so-called surface mount manufacturing techniques. Slots in the sides of the block that preferably run between the input-output pads can reduce coupling between the input/output pads and permit adjustment of high-side transmission zeroes by changing the dimensions of the slots. No wired connections to the ceramic bandpass filter block are required.
