Title:
WAVEGUIDE FILTER HAVING ADJUSTABLE BANDWIDTH
Document Type and Number:
WIPO Patent Application WO/2019/109735
Kind Code:
A1
Abstract:
Disclosed is a waveguide filter having an adjustable bandwidth, comprising: a cavity; an input end and an output end arranged at the cavity; and at least three coupling windows. A first dielectric rod capable of bandwidth adjustment is provided in each coupling window. A distance to which the first dielectric rod is inserted into a resonant cavity is adjustable. At least three first dielectric rods are driven by the same driving device. The present invention employs a transmission mechanism to synchronously control bandwidth adjustment for multiple coupling windows, such that the number of required driving motors is reduced, thereby greatly reducing costs of a filter, simplifying the structure of the filter, increasing adjustment precision, and reducing size and weight of the filter.
