ABSTRACT:
A duplexer for a radio transceiver is disclosed in which two volumes of dielectric material each have at least two holes and each is covered with a conductive material except for one surface. An electrode on the one surface of each volume is coupled to one of the holes and is coupled to a substrate via a terminal passing through a mounting device. The substrate provides coupling between the terminals of the two volumes and a common antenna.
