Abstract
A filter capable of adjusting frequency and bandwidth for dynamically setting at least one of the filter center frequency and bandwidth includes a first movable member, a second movable member, an upper casing, a lower casing, multiple conductive clamping members, a cavity and a driving module. The first and second movable members have multiple first and second lugs formed on the first and second boards respectively. The upper and lower casings have multiple upper and lower openings corresponsive to the first lugs and the second lugs respectively. The conductive clamping members are corresponsive to the upper openings and the lower openings. The cavity has multiple chambers and multiple connecting portions. The driving module changes the position of the first movable member to determine the filter center frequency and the position of the second movable member to determine the bandwidth.
