Abstract
A substantially circular electrodeis arranged on a surfaceA of a dielectric substrateof a TM010-mode resonator. A coupling line, which extends along a diameter of the substantially circular electrode, is arranged on a back surfaceB of the dielectric substrate, and back-surface electrodesare arranged with the coupling lineinterposed therebetween in the width direction. Furthermore, signal linesand ground electrodesare arranged on a surface of an external substratein positions other than portions facing the coupling lineof the TM010-mode resonator. The signal linesare connected to the coupling lineof the TM010-mode resonatorand the ground electrodesis connected to the back-surface electrodes
