Abstract
A wave filter having two or more dielectric resonators of substantially tubular shape juxtaposed on a base structure with their longitudinal orientations reversed alternately. The resonator terminals are therefore staggered on both sides of the juxtaposition of the resonators and thus better electrically isolated from one another than if all the resonators are oriented in the same longitudinal direction. The base structure is of ceramic material, having coupling elements, terminals, and all necessary electrical connections formed thereon or embedded therein.
