Abstract
Provided are an integrated dielectric resonator filter and a clock extraction device using the integrated dielectric resonator filter. The integrated dielectric resonator filter includes: a microwave substrate; a disc type dielectric resonator installed on the microwave substrate and having predetermined diameter and height; an input and output transmission line installed on both sides of the disc type dielectric resonator to transmit input and output signals; and a metal cover enclosing the disc type dielectric resonator to form a predetermined volume, opened toward the input and output transmission line, and closed in an orthogonal direction to the input and output transmission line.
