1. A multi-band multi-path receiving and transmitting device capable of being coupled to a broadband antenna and a signal processing module, the multi-band multi-path receiving and transmitting device comprising:

  • at least two multi-frequency couplers; and

    a multi-band transceiver, whereinthe at least two multi-frequency couplers are configured to transceive, from the broadband antenna, at least a first frequency band signal and a second frequency band signal;

    the at least two multi-frequency couplers comprise a first multi-frequency coupler and a second multi-frequency coupler, the first multi-frequency coupler is configured to receive the first frequency band signal and the second frequency band signal sent by the broadband antenna, and send the first frequency band signal and the second frequency band signal to the multi-band transceiver, and the second multi-frequency coupler is configured to receive the first frequency band signal and the second frequency band signal sent by the broadband antenna, and send the first frequency band signal and the second frequency band signal to the multi-band transceiver;

    the multi-band transceiver comprises at least two first frequency band receiving branches and at least two second frequency band receiving branches, the at least two first frequency band receiving branches are configured to receive the first frequency band signal sent by the first multi-frequency coupler and the second multi-frequency coupler, and send the first frequency band signal to the signal processing module, and the at least two second frequency band receiving branches are configured to receive the second frequency band signal sent by the first multi-frequency coupler and the second multi-frequency coupler, and send the second frequency band signal to the signal processing module; and

    the signal processing module is configured to receive the first frequency band signal sent by the at least two first frequency band receiving branches, and process the first frequency band signal; and

    receive the second frequency band signal sent by the at least two second frequency band receiving branches, and process the second frequency band signal.
