Abstract
A cavity filter includes an enclosure, resonators secured inside the enclosure, a lid, a slider, and a driving device. The enclosure includes a bottom portion, sidewalls extending from edges of the bottom portion to define a cavity. Each sidewall defines a positioning portion at a top surface thereof. The lid covers the enclosure. The slider includes tuning cells each partially coated with metal and positioned opposite to one of the resonators. The slider is movably disposed between the lid and the resonators and slides on the positioning portions. The driving device is located inside the enclosure and drives the slider to move along the positioning portions to adjust a resonating frequency of the cavity filter.
