Abstract
A process for producing a dielectric filter by bonding coaxial dielectric resonators of predetermined size as arranged side by side. The process comprises forming interstage coupling windows by removing an outer conductor layer from the same region of each of adjoining surfaces of the resonators to be adjacent to each other, and bonding the resonators as arranged side by side in proximity to each other on a smooth-surfaced table with an electrically conductive bonding material applied to at least one of the outer conductive layers remaining on the adjoining surfaces.
