Abstract
A dielectric duplexer device is provided with an output terminal pad formed on a side surface of a dielectric block in the vicinity of an open end associated with a plurality of resonators of a reception section in such a manner as to face the resonators. An extension electrode extends from the output terminal pad onto an end face of the dielectric block where the open end is present, to thereby be capacitively coupled with the resonators. The coupling capacitance can be readily corrected by adjusting the position of the end of the extension electrode. In one specific form, when the dielectric duplexer is mounted, the extension electrode is exposed and is also joined to a predetermined conductive path by means of solder. Accordingly, the output terminal pad is soldered at the bottom and side surfaces thereof to thereby be fillet-soldered, thereby providing visibility of electrical and mechanical connections thereof to the predetermined conductive path and thus enhancing the reliability of the mounted state.
