Abstract
A tunable filter for dynamically setting a filter center frequency includes a movable member, an upper casing, a lower casing, conductive gaskets, a cavity and a driving unit. The movable member includes a board and lugs. The upper casing includes upper openings corresponsive to the lugs respectively. The lower casing includes lower openings corresponsive to the upper openings respectively. The conductive gaskets are disposed between the upper and lower casings. The cavity is combined with the lower casing and has chambers, and the conductive gaskets are corresponsive to the upper and lower openings respectively. The driving unit is coupled to the movable member for moving the lugs in a first direction towards the chambers or in a second direction away from the chambers. The distance moved by the lugs in the first direction or the second direction is used for determining the filter center frequency.
