Abstract
Coaxial resonators serving as input and output stages are arranged on a dielectric substrate having input and output coupling strip lines and a grounding electrode formed in the same plane as the strip lines and surrounding the strip lines. The substrate is shaped substantially in conformity with the bottom contour of the resonators as arranged on the substrate.
