Cylindrical waveguide resonator filter section having increased bandwidth.

摘要

A high Q microwave filter is disclosed. Coupling bar structures (16, 17) are included in a cylindrical resonator (10), extending substantially the entire length of the resonator (10) for coupling orthogonal modes (1, 2). Fine tuning may be provided by inserting tuning screws (12, 13) into the cylindrical resonator (10).
