Abstract

Embodiments of the present invention relate to the field of electronic communications technologies, and provide a tunable filter and a tunable filtering device, to resolve a problem that an existing tunable E-plane filter has a relatively poor filtering effect. 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.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of electronic communication, and in particular, to an adjustable filter and an adjustable filtering device. Background technique [0002] Tunable filters are an important part of microwave communication systems and are widely used in frequency hopping radio stations, electronic countermeasures, multifunctional receivers, and dynamic frequency allocation systems. [0003] At present, there is an E-plane tunable filter with simple structure and convenient frequency adjustment. Such as figure 1 As shown, the rectangular waveguide in the E-plane tunable filter is divided into a first waveguide part 11 and a second waveguide part 12 along the E-plane of the rectangular waveguide at the center of its H-plane, and they are arranged parallel to the E-plane The metal plate 13 is sandwiched by the first waveguide portion 11 and the second waveguide portion 12. Furthermore, at least one die...
