An RF filter includes an insulating layer(506), an elastic body(504), a connection bar and a pressing plate. The insulating layer is coated in an inner wall of a groove of a resonator. The elastic body is connected to a tuning bolt(502) or the insulating layer and is fixed in one of the lower part of the tuning bolt and the insulating layer. The elastic body is contracted or released according to the movement of the tuning bolt and provides the repulsive power by the elasticity of the tuning bolt when completing the tuning of the tuning bolt. The insulating layer is made of the Teflon material. A connection bar is extended in the lower part of the tuning bolt. The pressing plate is combined in the connection bar. The elastic body is fixed in one of the pressing plate or the insulating layer and is contracted or released according to the movement of the pressing plate. |
