Resonant circuit device

Abstract

Abstract PURPOSE:To perform resonance frequency adjustment without decreasing a Q value on an unloaded condition, by providing a dielectric resonator having a through hole, a dielectric rod to be inserted into said through hole, and a means of regulating the position relation between the dielectric resonator and dielectric rod. CONSTITUTION:A cylindrical dielectric resonator 1 having a columnar through hole 8 is fixed with an adhesive, etc., on the top surface of a dielectric substrate 2 fixed on an earth conductor 3, constituting a container, by an adequate method such as soldering, etc. In the dielectric substrate and container 3, a through hole 7 is made, and a dielectric rod 4 fixed to an adusting screw 5 at its one end with an adhesive, etc., is positioned in the through hole 7 and dielectric resonator through hole 8. Further, a screw with the same diameter with the adjusting screw 5 is formed in the container 3 and the adjusting screw 5 is turned up or down to adjust the vertical position relation between the dielectric rod 4 and dielectric resonator.
