BROADBAND SIGNAL RECEIVING METHOD AND DEVICE, RADIO-FREQUENCY PROCESSING UNIT AND BROADBAND ANTENNA

摘要

Embodiments of the present invention provide a broadband signal receiving method and apparatus, a radio frequency processing unit, and a broadband antenna, which can reduce costs of a multi-frequency receiving solution, remove a combined insertion loss of an RU module, reduce a risk of passive intermodulation, and further improve performance of receiving a signal by the RU module. The apparatus includes: a preconfiguring unit, a filter unit, and a signal receiving and processing unit, where the preconfiguring unit is configured to preconfigure predetermined operating frequency bands of a filter unit and a signal receiving and processing unit of each receive channel, where the predetermined operating frequency band includes at least one frequency band; the filter unit is configured to perform filtering on a radio frequency signal received from a broadband antenna by a receive channel in which the filter unit is located, to obtain a filtered signal of a predetermined operating frequency band; and the signal receiving and processing unit is configured to receive and process a signal that is of the predetermined operating frequency band and in the filtered signal obtained by the filter unit of the receive channel in which the signal receiving and processing unit is located. The embodiments of the present invention are applicable to the field of communications technologies.
