Disclosed is a transceiver device for a satellite ground station. The transceiver device comprises an antenna module and an integral radio frequency module. The antenna module comprises an antenna and a feed. The integral radio frequency module comprises a housing. The housing is provided with a connection portion connected to the feed. The housing is also provided with an intermediate-frequency reception signal N head, an intermediate-frequency transmit signal N head, and a power supply N head. An orthomode transducer, a reception filter, a transmit filter, a low-noise amplifier, a power amplifier, a first frequency-mixer and a second frequency-mixer are integrated in the housing. The first frequency-mixer is connected to the intermediate-frequency reception signal N head, and the second frequency-mixer is connected to the intermediate-frequency transmit signal N head. Also disclosed is a satellite communications system. Embodiments of the present invention improve convenience in upgrading and maintaining devices, reduce costs while devices are integrated, improve the reliability and scalability of a system, and achieve platformization. |
