MICROWAVE COMMUNICATION DEVICE AND MICROWAVE COMMUNICATION SYSTEM

摘要

The present invention discloses a microwave communications device and a microwave communications system. The microwave communications device includes: a first converting module and a second converting module, configured to perform mutual conversion between a baseband signal or an intermediate frequency signal and a microwave signal, where microwave signals received or output by the first converting module and the second converting module respectively have a first polarization direction and a second polarization direction, and the first polarization direction and the second polarization direction are the same or perpendicular to each other; and an orthomode transducer, configured to perform separation and synthesis of orthogonally polarized microwave signals, where the orthomode transducer includes a first waveguide port, a second waveguide port, and a third waveguide port, where polarization directions of microwave signals received or output by the first waveguide port and the second waveguide port are perpendicular to each other, and the first waveguide port and the second waveguide port are respectively connected to the first converting module and the second converting module. The microwave communications device and system in embodiments of the present invention can, by providing dual channels and integrating an orthomode transducer inside the microwave communications device, increase a transmission capacity while improving equipment application flexibility, reducing installation complexity, and lowering costs.
