PURPOSE:To provide a dielectric resonant parts and its production which can easily change the coupling degree and the coupling relation between both resonators adjacent to each other without changing the external shape and the size of a dielectric block nor deteriorating the Qo. CONSTITUTION:A dielectric block 1 includes three resonator holes 2a, 2b and 2c, and the center hole 2b tilts to both end faces 1a and 1b. Meanwhile other side holes 2a and 2c are set vertical to both faces 1a and 1b respectively. In such a constitution, the inductive coupling is secured between the resonators of one of both resonator holes adjacent to each other with the capacitive coupling secured between the resonators of the other of both reaonator holes respectively. These coupling degrees can be changed by changing the tilting degree of the hole 2b. This tilting hole 2b can be formed by the cutting process of an ultrasonic processing machine. |
