DIELECTRIC CERAMIC FILTER

The present invention relates to a dielectric ceramic filter including a dielectric block filled with a ceramic material and having an outer surface surrounded by a metal component, a resonance part provided in the dielectric block, having a space having a circular horizontal cross-section, and separated from the dielectric block by a metal film, and a tuning cover coupled to the dielectric block, configured to cover one side of the resonance part, and positioned at a portion corresponding to the resonance part, the tuning cover being configured to tune a frequency of the resonance part by being deformed in shape corresponding to a space of the resonance part, thereby increasing a production yield and implementing a high Q value when the volume remains the same.
