A cavity filter comprises a housing which defines an internal cavity, first and second resonators in the internal cavity, and a metal coupling sheet. The first resonator has first and second spaced apart coupling panels, and the second resonator has third and fourth spaced apart coupling panels. The metal coupling sheet has a first coupling section positioned between the first coupling panel and the second coupling panel and a second coupling section positioned between the third coupling panel and the fourth coupling panel.
