Abstract
A cavity filter and a RF communication device including the cavity filter are disclosed. The cavity filter includes a cavity body, a cover plate, a resonance rod, a tuning screw, and a supporting member. The cover plate caps the cavity body to form a resonance cavity. The resonance rod is a tube with an opening at one end, where the opening end is combined with the cover plate or the cavity body. The supporting member is mounted to the cover plate or the cavity body to further secure the tuning screw to the resonance rod, and pushes the tuning screw along an axial direction of the resonance rod against the bottom end of the resonance rod, so as to make the resonance rod undergo an elastic deformation and thus adjust the RF parameters of the cavity filter.
