Abstract

Disclosed is a tunable filter using a sliding system. The disclosed filter comprises: a housing in which a plurality of cavities are defined by partitions; resonators accommodated within the respective cavities; a cover coupled to an upper portion of the housing; a sliding member which is slidably arranged on the cover, and to which a plurality of tuning elements are coupled; and a polymer actuator, the length of which is variable so as to provide the sliding member with driving force. The tuning elements are inserted into the sliding member via holes formed in the cover, and slide in correspondence to the sliding of the sliding member. According to the disclosed filter, the sliding operation can be controlled by a structure that is more compact when compared to a structure that uses a motor, and manufacturing costs can be reduced.
