Title:
CIRCULAR FILTER ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2022/199254
Kind Code:
A1
Abstract:
The present application relates to the field of wireless communications, and discloses a circular filter assembly. The circular filter assembly comprises: a dielectric filter; and a dielectric waveguide circulator, the dielectric waveguide circulator being provided with at least three end portions, one end of the dielectric filter being connected to one end portion among the three end portions, a cascade matching window being provided at the connection of the dielectric filter and the end portion, and the cascade matching window being used for adjusting the impedance of the circular filter assembly. The dielectric waveguide circulator and the dielectric filter are integrally formed. The dielectric waveguide circulator and the dielectric filter are integrally formed, such that connecting members between the dielectric waveguide circulator and the dielectric filter can be reduced; moreover, the cascade matching window is additionally provided to perform impedance adjustment, so as to obtain the same standing-wave indicator as that obtained by means of a conventional connection mode using a connector. Compared with the conventional connection mode using a connector, the present application can reduce the insertion loss and the power consumption is lower.
