Abstract

PURPOSE: To improve the positioning accuracy of a resonant frequency tuning capacity and input-output coupling capacity against each other, by forming the two capacities in parallel plates united in one body.
CONSTITUTION: This parallel-plate capacities 106 made of ceramics, etc., have capacity forming electrodes 107, the section 104 of a resonant frequency tuning capacity, section 105 of an input-output coupling capacity, and no-electrode section 108 on the upper surface of the upper plate. By forming the no-electrode section 108 and separating the electrodes 107, from each other, the capacities 104 and 105 are formed in one parallel plate capacity, in other words, the capacities 104 and 105 are united in one body. Therefore, the number of parts of the capacities to be mounted on a ring-shaped resonator is reduced and the capacities are easily fixed by sticking. In addition, the positioning accuracy of the two capacities against each other can be improved.
