ABSTRACT:
A dielectric filter which includes a dielectric block having a plurality of through-holes defined therein so as to extend parallel to each other and spaced a predetermined distance from each other. Each of the through-holes has a peripheral wall lined with an electroconductive material to provide a respective hole electrode. This hole electrode has an isolation region dividing such hole electrode into two separate electrode components. The dielectric filter also has at least one terminal member provided within one of the through-holes and coupled through a dielectric element separate from the dielectric block.
