Abstract
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.
