Problems solved by technology
[0005] However, in the method adopted in the prior art, RU modules of different frequency bands share the antenna port through the added combiner, and the increase of the combiner itself causes an increase in material cost, and the engineering connection is complicated. The use of the RU module increases the combined loss and the risk of passive intermodulation

Embodiments of the invention provide a broadband signal receiving method and a broadband signal receiving device, a radio frequency processing unit, and a broadband antenna, capable of reducing costsof a multi-frequency receiving solution, removing the combined insertion loss of an RU module, reducing the risk of passive inter-modulation, and further improving performance of receiving a signal bythe RU module. The device includes: a pre-configuring unit, filter units, and signal receiving and processing units, wherein the pre-configuring unit is configured to pre-configure predetermined operating frequency bands of the filter units and the signal receiving and processing units of each receive channel, wherein the predetermined operating frequency bands include at least one frequency band; the filter units are configured to perform filtering on radio frequency signals received from a broadband antenna by the receive channels in which the filter units are located, to obtain a filteredsignal of a predetermined operating frequency band; and the signal receiving and processing units are configured to receive and process the signals that are of the predetermined operating frequency bands and in the filtered signal obtained by the filter units of the receive channels in which the signal receiving and processing units are located. The embodiments of the invention are applicable to the technical field of communications.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for receiving broadband signals, a radio frequency processing unit and a broadband antenna. Background technique [0002] With the increasing demand for bandwidth for data services in the Mobile Broadband (MBB) era, the performance benefits of improving network uplink traffic through 4Way Receiver (4Rx for short) or multi-way receivers have been operational Approved by manufacturers and equipment manufacturers. [0003] In the prior art, the processing capability of the radio process unit (RU) module of the existing site, which can also be called the existing site, is mostly 1 transmit 2 receive (1 transmit 2 receiver, 1T2R) or 2 transmit 2 receive (2 transmit 2 receiver, 2T2R ) mainly. The receiving capacity of the existing antenna system is limited. In order to increase the network uplink traffic, it is necessary to add a combiner to share the anten...
