摘要： The adjustable resonator according to the invention has a casing, which is composed of walls, a lid and a bottom, a resonator cavity inside the casing and an internal conductor inside the resonator cavity, which internal conductor is in electric contact with the casing. The resonator further comprises a moveable adjustment piece, which comprises a conductive adjustment member, a conductive upper plate, and a dielectric support member. The adjustment member has a stem, which is vertical, and a cap as an expansion thereof. The adjustment member can be moved downwards so that its stem and the fixed internal conductor connected to the bottom of the resonator go within each other. The movement of the adjustment piece in the coaxial resonator first decreases the resonance frequency and then slowly increases it. Therefore the resonator provides a very wide adjustment area for the resonance frequency.

摘要： An improved microwave cavity filter used in cellular communication systems such as base stations is disclosed. The cavity filter has a conductive housing forming a cavity therein and a hollow conductive resonator configured in the cavity with a folded hat shaped upper portion. A tuning screw extends from the top cover of the housing into the top folded hat portion of the hollow resonator to fine tune the resonator. The resonator also may preferably include two different diameter sections providing a first high impedance section with smaller diameter and a second lower impedance section with a larger diameter configured at an upper end of the resonator. This configuration provides a significantly smaller cavity height for a given power handling capability. The resonator is preferably of constant thickness allowing low cost stamping or other forming techniques to be used in forming the resonator.

The base has a plurality of output terminal with metallic conductor extending into the inner side formed on the surface of the sidewall. The base has resonance space formed indented to receive the metallic conductor and extending to connect to the through groove. The lid has a plurality of threading holes formed corresponding to chambers and partitions received with adjusting elements for height adjustment. The adjusting elements has the resonance bars corresponding to every chamber and the suppressing bars corresponding to every partition. By adjusting suppressing bar and the partition to a predetermined distance, the space of the channel for transmitting the high-order harmonic wave can be reduced to suppress noise produced by high-order harmonic wave.
