Abstract: Embodiments of the present invention provide a tunable filter and a tunable filtering device. The tunable filter includes: a cavity, a filtering component that is in the cavity and that is provided on a first surface thereof with at least one through hole, a drive mechanism, and at least one first adjustable component and at least one second adjustable component that are connected to the drive mechanism and that run through the first surface of the cavity; one end of one first adjustable component is disposed opposite to one of the at least one through hole; one end of one second adjustable component is disposed opposite to a position between two adjacent through holes in the at least one through hole; and the drive mechanism controls the at least one first adjustable component to synchronously move, and controls the at least one second adjustable component to synchronously move.

Abstract: A tunable filter includes a first waveguide body, a second waveguide body, a metal plate, a tuning piece, and a driving piece. A first cavity is disposed in the first waveguide body, and a second cavity is disposed in the second waveguide body. The metal plate is sandwiched between the first waveguide body and the second waveguide body, multiple windows are disposed on the metal plate, and the first cavity and the second cavity are in communication and are symmetrically distributed on both sides of the metal plate. The tuning piece includes a dielectric pull-rod and multiple metal sheets connected to the dielectric pull-rod, the dielectric pull-rod protrudes out of the first waveguide body and is connected to the driving piece, the multiple metal sheets are disposed inside the first cavity, and the multiple metal sheets are disposed corresponding to the multiple windows.
