Filter for communication device

The utility model relates to a filter for communication equipment, in particular to a filter for communication equipment, which structurally comprises a filter main body provided with a cavity serving as a dielectric filling space, and an opening at the bottom of the cavity; a lower cover plate made of a first material coupled to the filter main body so as to cover the bottom of the opening of the filter main body; and a resonator frame of a second material coupled to the lower cover plate and provided with a plurality of resonator bars extending a predetermined length toward the upper surface of the filter body, the resonator frame being formed on the lower cover plate so as to pass through the inside and outside of the cavity. After the lower end part is forcibly buckled and combined with more than two rows of buckling through holes arranged in the width direction in a manner of being separated along the length direction, the peripheries of the plurality of buckling through holes are fixed on the inner side
