A radio frequency filter is provided to improve operation reliability of the RF(Radio Frequency) filter by reducing a passive modulation distortion by minimizing contact non-linearity of the RF filter. A radio frequency filter includes a housing body(10), a resonance metal bar(12), a housing cover(20), and a housing seal layer(30). Containing spaces are defined by barrier ribs. The resonance metal bar is coupled with a center of the containing space. The housing cover includes a tuning screw at a position between the center of the containing space of the resonance metal bar and the barrier rib. The housing seal layer is arranged between the housing cover and the housing body. The housing seal layer has a first melting point and tightly couples the housing cover with the housing body, such that no contact non-linearity is generated between the contact areas. |
