Abstract: A ceramic monoblock filter incorporating a top face input/output port metallization pattern defining an input/output transmission line, a power load distribution bar, and a ground plate. The transmission line, power load distribution bar, and ground plate are all positioned and oriented relative to each other and two of the resonators defining the filter to define load splitting capacitors providing increased power load handling characteristics.

Abstract: A coaxial resonator includes a core of dielectric material. A through-hole defines respective openings in the top and bottom surfaces of the core. The top surface further defines at least first and second metallized regions surrounding the through-hole opening and an unmetallized region therebetween. The first metallized region defines a resonator pad. An isolated metallized region on at least one of the side surfaces defines an input/output electrode. In one embodiment, one of the metallized regions on the top surface and the electrode define interdigitated fingers on the top surface. In another embodiment, the pad defines outwardly projecting corner ears and both the second metallized region and electrode define fingers protruding between the ears. In a further embodiment, the electrode extends across at least two of the side surfaces.
