Abstract
The present invention relates to a switchable filter comprising: a filter unit in which a first filter group for filtering the frequency of a first frequency band is provided on one surface thereof and a second filter group for filtering the frequency of a second frequency band is provided on the other surface thereof on the basis of a center partition wall; and a frequency band switching unit, which moves to be adjacent to or separated from the one surface or the other surface of the filter unit, and thus converts a frequency band into the first frequency band or the second frequency band. Therefore, the deterioration of RF characteristics is prevented and selective conversion between frequency bands is facilitated.
