A combline stripline filter includes a number of conductive strips, each connected to ground on one end and capacitively loaded to ground at the other end. Input and output pads will make a surface mountable connection to a printed circuit board. Tuning is provided for by removing ground over the extension ends of the outside resonators. The center resonators are tuned by removing metal from areas on the cover that are connected to the resonators by plated through holes. Undesired capacitance is compensated for by rounding the ends of the resonators and the opposing ground planes.
