RF CAVITY FILTER FOR PREVENTING DETERIORATION BY PIMD AND TUNING STRUCTURE APPLIED TO THE FILTER

摘要

PURPOSE: By preventing the drops characteristic due to PIMD the RF cavity filter for preventing the drops characteristic by the PIMD and the tuning structure of being thus applied to prevent the dielectric breakdown phenomenon due to the high power. CONSTITUTION: A plurality of cavities(308) defined with partition walls inside the housing(300). A plurality of resonators(310) is accepted to cavity. The cover(302) is combined on the top of the housing. In a plurality of rotating members(304) is cover, it is inserted to the cavity inside. A plurality of tuning elements(306) is combined in the lower part of the rotating member. It is spaced on the top of resonator predetermined and tuning elements are arranged.
