摘要： The present disclosure provides a radio frequency filter having a cavity structure including a housing, a cover and a resonance element. The housing has a hollow interior for providing a cavity, and an open side. The cover shields the open side of the housing. The resonance element is positioned in the hollow interior of the housing, and has a planar portion and a support for supporting and fixing the planar portion to the housing. The planar portion of the resonance element has at least two through holes, and the support has a lower end portion formed with a male thread structure for screw fastening. The housing is formed with a female thread structure to be screw fastened with the male thread structure formed at the lower end portion of the support.
