description The utility model discloses a cavity filter belongs to radio frequency products technical field. The utility model discloses a cavity filter includes the casing, with the apron of casing lock and setup the tuning plug in the casing, the position that the apron corresponds the tuning plug is provided with the frequency modulation piece, has the clearance between apron and the tuning plug, the frequency modulation piece can be carried out power control with the distance that changes between frequency modulation piece and the tuning plug according to the compressive strain, the apron still is provided with transfers the coupling piece, transfers the coupling piece to set up between adjacent two frequency modulation pieces, transfers the coupling piece can be transferred coupling belt wide according to the compressive strain. The utility model discloses a cavity filter can reduce the requirement of lid plate thickness through cancellation tuning screw's setting to through direct with thefrequency modulation piece
