Embodiment 1

[0035] A radio frequency module provided by an embodiment of the present invention includes:

[0036] A bandpass filter is set between the port of the first radio frequency channel and the port of the second radio frequency channel in the radio frequency module of the base station;

[0037] The bandpass filter is built in the radio frequency module of the base station.

[0038] In a radio frequency module provided by an embodiment of the present invention, a bandpass filter is provided between the port of the first radio frequency channel and the port of the second radio frequency channel in the radio frequency module of the base station, and the bandpass filter is built in In the radio frequency module of the base station, the port of the second radio frequency channel is used as a combiner port to connect to the port of the radio frequency channel in another radio frequency module of the base station, so as to realize antenna feeder sharing of two frequency bands. The embod...

Embodiment 2

[0062] A multi-band antenna feeder sharing method provided by an embodiment of the present invention, such as Figure 17 As shown, the first radio frequency module works in frequency band 1, and the second radio frequency module works in frequency band 2. The specific operation steps include:

[0063] 1701.

Abstract

The embodiment of the invention discloses a multi-band antenna feeder sharing method and a base station radio frequency unit, and the invention relates to the technical field of base stations. The method includes: when the first radio frequency module is working in the built-in combination mode, receiving the signals of frequency band 1 and frequency band 2 through the antenna feeder, and transmitting them to a band-pass filter for filtering processing to obtain the signal of frequency band 2, and The signal of frequency band 2 is transmitted to the third radio frequency port through the combiner port; and / or, when the first radio frequency module is working in the built-in combiner mode, the signal of frequency band 2 is sent to the combiner port through the third radio frequency port, and the frequency band The signal of the second frequency band is transmitted to the port of the first radio frequency channel through the band-pass filter, and sent out through the antenna feeder together with the signal of the frequency band one. The embodiment of the present invention is mainly applied in the processing process of multi-band antenna feeder sharing.

Description

technical field [0001] The present invention relates to the technical field of base stations, in particular to a multi-band antenna feeder sharing method and a base station radio frequency unit. Background technique [0002] With the development of wireless communication, wireless spectrum resources are becoming more and more scarce, and the situation of multi-band co-site is becoming more and more common, which requires an additional antenna feeder system. Therefore, various multi-band shared antenna feeder technologies have emerged as the times require. [0003] In the process of realizing the present invention, the inventor found that in the prior art, a built-in combiner is used to realize multi-band combination and antenna feeder sharing, such as figure 1 As shown, the radio frequency module (RFModule) of frequency band 2 realizes the combination of two frequency bands through the built-in combiner of the RF Module of frequency band 1, and the antenna feeder is shared, ...
