A dielectric filter

摘要

A dielectric filter comprises a plurality of coaxial resonators each having an outer peripheral conductor and an inner peripheral conductor formed by an outer peripheral surface and an inner peripheral surface of a dielectric member with a conductive member and having one end face short-circuited, wherein at least one of said plurality of coaxial resonators has a length different than that of the other coaxial resonators, and has the same basic resonance frequency as that of said other coaxial resonators by a resonance frequency correcting capacitance connected to the inner peripheral conductor.
