Embodiments of the present invention provide a multi-frequency band antenna feeder sharing method and a base station radio frequency unit. The present invention relates to the field of base station technologies. The method includes: when a first radio frequency module works in set-in combiner mode, receiving a signal of a frequency band 1 and a signal of a frequency band 2 through an antenna feeder, transmitting the signals to a band-pass filter and filtering the signals so as to obtain the signal of the frequency band 2, and transmitting the signal of the frequency band 2 to a third radio frequency port through a combiner port; and/or, when the first radio frequency module works in set-in combiner mode, sending the signal of the frequency band 2 to the combiner port through the third radio frequency port, transmitting the signal of the frequency band 2 that has passed through the band-pass filter to the port of the first radio frequency channel, and sending out the signal of the frequency band 2, together with the signal of the frequency band 1, through the antenna feeder. |
