Abstract:
1. A microwave communications device, comprising: an orthomode transducer, a first converter and a second converter, wherein the orthomode transducer comprises a first waveguide port connected to the first converter, a second waveguide port connected to the second converter and a third waveguide port connected to an antenna system; the orthomode transducer is configured to separate microwave signals received from the antenna system to first microwave signals to be transmitted to the first converter and second microwave signals to be transmitted to the second converter, and to synthesize third microwave signals received from the first converter and fourth microwave signals received from the second converter; the first converter is configured to receive the first microwave signals from the orthomode transducer through the first waveguide port, convert the first microwave signals into first baseband signals or first intermediate frequency signals to be sent to a microwave indoor unit or a base station, convert third baseband signals or third intermediate frequency signals transmitted from the microwave indoor unit or the base station into the third microwave signals and transmit the third microwave signals to the orthomode transducer through the first waveguide port; the second converter is configured to receive the second microwave signals from the orthomode transducer through the second waveguide port, convert the second microwave signals into second baseband signals or second intermediate frequency signals to be sent to the microwave indoor unit or the base station, convert fourth baseband signals or fourth intermediate frequency signals transmitted from the microwave indoor unit or the base station into the fourth microwave signals and transmit the fourth microwave signals to the orthomode transducer through the second waveguide port; wherein the first microwave signals have a first polarization direction, the second microwave signals have a second polarization direction, the first polarization direction and the second polarization direction are perpendicular to each other; and wherein the third microwave signals have a third polarization direction, the fourth microwave signals have a fourth polarization direction, the third polarization direction and the fourth polarization direction are perpendicular to each other.
