Abstract:
A dielectric filter comprisinga dielectric block in a substantially rectangular parallelepiped shape, having a pair of opposite parallel end-faces and plural sides extending between the paired opposite end-faces, one of said plural sides being a mounting face; plural resonator holes elongating through the inside of the dielectric block across the paired opposite end-faces; inner conductors provided on inner walls of the plural resonator holes, respectively; an outer conductor provided on the sides and one of the end-faces of the dielectric block; a beveling portion provided in an edge portion between one of the paired opposite end-faces and the mounting face; and input-output electrodes provided to extend over the one of the paired opposite end-faces and the beveling portion, separated from the outer conductor, and capacitance-coupled to respective ones of the inner conductors.
