Document Type and Number:
WIPO Patent Application WO/2021/017574
Kind Code:
A1
Abstract:
An infrared filter, comprising an input end (1), an output end (2), a filter cavity (3), and a filter assembly (8), wherein an input end (1) and an output end (2) are both SMA connectors; an inner conductor (7), a filter assembly (8) and an attenuator (6) are arranged in the filter cavity (3). The infrared filter uses a highly matched infrared absorbing material with a suitable dielectric constant as the main body of the filter, which can effectively absorb mixed infrared waves in a microwave communication transmission path; by means of attenuator technology, the infrared filter has a very good standing wave index in the microwave frequency band, and it is easy to produce, assemble and debug; moreover, the device is small in size and stable in performance, which can easily meet the current related system requirements.
