INCORPORATED DIELECTRIC FILTER

摘要

PURPOSE: An incorporated dielectric filter is provided to obtain desired attenuation characteristics while minimizing an insertion loss by enabling electrical coupling adjustment through the control of the size of a metal coupling region. CONSTITUTION: A conductive electrode is formed on the entire surface of a dielectric block having through holes(101, 102). A partial electrode of a third side(300) paralleled with the through holes(101, 102) is removed to form input and output electrodes(301, 302). The remaining electrode except for the partial electrode between the through holes(301, 302) is removed from a first side(100). The partial electrode of the third side(30) is removed to form an electrode region. A metal coupling region(303) connected from the first side(100) to the third side(300) is formed.
