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 and at least two second frequency band receiving branches; 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,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, andwherein 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 also configured to receive the second frequency band signals from the at least two second frequency band receiving branches and process the second frequency band signals.
