DIELECTRIC FILTER AND DIELECTRIC DUPLEXER

Title:

DIELECTRIC FILTER AND DIELECTRIC DUPLEXER

Document Type and Number:

Japanese Patent JPH1075104

Kind Code:

A

Abstract:

To provide a dielectric filter in which parts are made common, manufacturing costs are reduced, and filter characteristics are good.

TM-double mode dielectric resonators 2, 3, 4, and 5 are arranged in one row, so that their openings can be faced to the same direction, and metallic panels 6 and 7 are attached with screws so as to cover the openings. An input loop 8 and an output loop 9 are arranged on the panel 6 to obliquely faced the crossing parts of dielectric poles 2xy and 5xy of the TM-double mode dielectric resonators 2 and 5, and almost V-shaped connecting loops 7a, 7b, and 7c are attached to it.
