1. A multi-band multi-path receiving and transmitting device, comprising:

  • a first multi-frequency coupler;

    a second multi-frequency coupler;

    a multi-band transceiver coupled with the first multi-frequency coupler and the second multi-frequency coupler, the multi-band transceiver comprising;

    at least two first frequency band receiving branches, at least two second frequency band receiving branches, and a first frequency band transmitting branch; and

    a signal processing module, coupled with the multi-band transceiver;

    wherein the first multi-frequency coupler is configured to receive a first frequency band signal and a second frequency band signal from an antenna, and to send the first frequency band signal and the second frequency band signal to the multi-band transceiver, and wherein the first multi-frequency coupler is further configured to receive another first frequency band signal from the multi-band transceiver, and to send the another first frequency band signal to the antenna;

    wherein the second multi-frequency coupler is configured to receive the first frequency band signal and the second frequency band signal from the antenna, and to send the first frequency band signal and the second frequency band signal to the multi-band transceiver;

    wherein the at least two first frequency band receiving branches are configured to receive the first frequency band signals from the first multi-frequency coupler and the second multi-frequency coupler, and to send the first frequency band signals to the signal processing module;

    wherein the at least two second frequency band receiving branches are configured to receive the second frequency band signals from the first multi-frequency coupler and the second multi-frequency coupler, and to send the second frequency band signals to the signal processing module;

    wherein the first frequency band transmitting branch is configured to receive the another first frequency band signal from the signal processing module, and to send the another first frequency band signal to the first multi-frequency coupler; and

    wherein the signal processing module is configured to receive the first frequency band signals from the at least two first frequency band receiving branches and process the first frequency band signals, and to receive the second frequency band signals from the at least two second frequency band receiving branches and process the second frequency band signals, and wherein the signal processing module is further configured to send the another first frequency band signal to the first frequency band transmitting branch.
