Title:
DIELECTRIC FILTER AND DIELECTRIC DUPLEXER
Document Type and Number:
Japanese Patent JP2004343281
Kind Code:
A
Abstract:
To provide a dielectric filter with high reliability the adjustment of a coupling amount of which is facilitated.
A part of a conductor layer at an outer circumferential edge of an upper face of a dielectric block above center axes of hollow holes is removed and the conductor layer of the outer circumferential edge is formed to be bridged over the conductor layers in the vicinity of resonator holes. Further, the conductor layer of the outer circumferential edge is formed to be interdigital and bridged over the conductor layers in the vicinity of the hollow holes and the capacitive coupling between the hollow holes is adjusted by adjusting the interdigital conductor layers through removal.
