Summary:There is disclosed a dielectric filter with attenuation pole having sharp attenuation characteristic. The dielectric block employed in the present dielectric filter is composed of a uniform integral dielectric single-block including TiO2, BaO. The dielectric block of this type comprises a plurality of resonators extending from a top surface toward a bottom surface thereof, a plurality of adjusting patterns provided over the top surface thereof, an outer conductor formed by side surfaces and the bottom surface thereof and grounded, input and output electrodes, wherein the adjusting patterns, the outer conductor, input and output electrodes are plated, for example, by silver, and insulted cable having one end connected to the outer conductor and the other end connected to the output electrode though a plurality of resonators thereabove.
