The utility model relates to a single double-channel filter based on a dielectric resonator. The filter comprises a metal shell sealed by a metal cover plate, a dielectric resonator is arranged in themetal shell, connected with the bottom of the metal shell and located in the center of the metal shell, a front input end is arranged on the front side wall of the metal shell, a rear output end is arranged on the rear side wall of the metal shell, a left input end is arranged on the left side wall of the metal shell, and a right output end is arranged on the right side wall; the front input endand the right output end are positioned at the upper part of the metal shell and are positioned at the same height; and the rear output end and the left input end are positioned at the lower part of the metal shell and are positioned at the same height. According to the single double-path filter, two paths of input and output are improved, the dielectric resonator is directly fixed at the bottom of the metal shell, and flu
