Abstract:
1. A ceramic monoblock filter, comprising: a block of dielectric material defined by top, bottom, and side surfaces wherein said side and bottom surfaces are covered substantially with a conductive material, the conductive material on at least one of the side surfaces defining a ground plate and the top surface defining opposed upper and lower peripheral longitudinal edges; a plurality of spaced-apart through-holes extending through the block between the top and bottom surfaces and surrounded on the top surface by conductive material defining conductive resonator plates; a first strip of conductive material on the top surface defining an input/output transmission line, the first strip of conductive material extending between first and second ones of the conductor resonator plates; a bar of conductive material defined on the top surface generally between the first and second ones of the resonator plates and the upper one of the opposed peripheral longitudinal edges, the bar of conductive material being separate and spaced from the first strip of conductive material and the ground plate; and means associated with the ground plate and/or the bar defining a power load splitting capacitor on the top surface.
