Disclosed are a tuning bolt ground connection structure and an RF cavity filter including the same. The disclosed filter comprises: a housing in which at least one cavity is defined; a cover which is coupled to the upper part of the housing; at least one resonator which is received in at least one cavity; at least one hole which is formed on the cover; at least one ground bolt formed with a screw thread on a portion of its outer surface and having a central hole; and at least one tuning bolt inserted into the inside of the housing through the center hole along screw threads formed on the inner surface of the center hole, wherein a flange section in contact with the lower part of the cover and the tuning bolt is formed in the lower part of the ground bolt. According to the disclosed filter, the generation of PIMD can be minimized in the tuning bolt ground connection structure and sufficient ground area is obtained. Furthermore, there is less impact to the outside environment such as by vibrations. |
