Abstract
A cavity filter that uses cross-coupling is disclosed, which includes: a housing, in which multiple cavities are formed, with the cavities being open towards a first direction; multiple resonators held respectively in the multiple cavities; and a coupling member arranged to pass through an aperture between a first cavity and a second cavity, from among the multiple cavities, such that the coupling member is positioned between a first resonator and a second resonator. Here, the coupling member includes a first extending portion and a second extending portion, the first extending portion is positioned closer to the first resonator than to the second resonator and extends towards one side of the housing along the first direction, and the second extending portion is positioned closer to the second resonator than to the first resonator and extends towards the other side of the housing along the first direction.
