Abstract
The present invention relates to a frequency cavity filter for improving data characteristics by reducing an assembly error, and a bolt used therefor. The frequency cavity filter comprises a housing where a plurality of cavities is defined by partition walls, a resonator that is accommodated in a specific cavity and a first bolt for fastening the resonator to the housing. Here, the resonator includes a specific hole into which the first bolt is inserted, and the hole is at least 3t (3mm) in length.
