A monoblock ceramic triplexer for connection to an antenna, a transmitter, a receiver and a GPS receiver is described. The triplexer includes a solid, monolithic core of dielectric material defining a plurality of through-holes extending between top and bottom surfaces. The surfaces of the core present a pattern of metallized and unmetallized areas including a relatively expansive metallized area, a transmitter coupling area, first and second receiver coupling areas spaced, an antenna coupling metallized area and an unmetallized area circumscribing at least one of the openings on the top surface. The antenna coupling metallized area includes a top surface extension towards the first receiver coupling area, and the expanded metallized area includes a top surface extension between adjacent resonator through-holes.

Ceramic RF triplexer

A duplexing filter suitable for use in a mobile communication system. The filter has a core of dielectric material with several through holes that define resonators . The core has metallized surfaces and except for the top surface . Several metallized resonator pads surround each of the through holes on the top surface . A metallized serpentine region extends from one or more of the resonator pads toward a side surface of the core . The metallized serpentine region causes attenuation of a third harmonic frequency.
