ABSTRACT:
A dielectric electronic component such as a dielectric duplexer includes a dielectric ceramic block, a plurality of resonators arranged in a row in the dielectric ceramic block, and at least one terminal pad formed on a side surface of the dielectric ceramic block and coupled to a selected one of the resonators. An attenuation adjustment electrode is provided on an end face of the dielectric ceramic block in the vicinity of the selected resonator. The attenuation adjustment electrode has a base conductor portion extending from the terminal pad and having an edge that faces the end of the selected resonator, and first and second adjustment conductor portions projecting from the base conductor portion and directly oppositely along a general path or direction defined by the arrangement of the resonators. The first and second adjustment conductor portions are selectively ground away in order to adjust the frequency of the attenuation peak of the frequency characteristics of the component.
