RESONATOR FILTER

摘要

PROBLEM TO BE SOLVED: To provide a resonator filter which can be made smaller and lighter and further improve productivity than a resonator filter having a general structure and composition.SOLUTION: A resonator filter includes: a metal case having a cavity inside; and a plurality of resonance bodies placed inside the case; and coupling means for electrically connecting the adjacent resonators respectively. The resonance filter also includes: a metal case having a cavity inside; and a conductor plate placed inside the case. The conductor plate includes: a support body electrically connected to the case; a plurality of resonators connected to the support body; and a coupling conductor for connecting the resonance bodies adjacent to one another at a point different from an end part where the plurality of resonators and the support body are connected.
