摘要： The present invention provides a receiver, a transmitter, a transmitter feedback device, a transceiver, a method for transmitting a multi-frequency band signal, a method for receiving a multi-frequency band signal, and a method for processing a transmitter feedback signal. The feedback device includes: a multi-channel frequency selection band-pass circuit, configured to receive a multi-frequency band feedback signal, and output a feedback signal of each frequency band in a multi-frequency band feedback signal in a time-division manner; a feedback local oscillator, configured to provide feedback local oscillation corresponding to each frequency band in a time-division manner; a mixer, configured to mix the feedback signal of each frequency band from the multi-channel frequency selection band-pass circuit and the feedback local oscillation corresponding to each frequency band from the feedback local oscillator, and output an intermediate frequency signal of each frequency band in a time-division manner. In the present invention, for a solution in which only one set of signal processing channels is used to process the signals of multiple frequency bands in the uplink, the downlink or both the uplink and downlink, the volume, power consumption, and cost do not increase significantly, and compared with the current multi-channel processing solution, the cost is reduced.
