An embodiment of the present invention provides a multi-beam forming apparatus, where the multi-beam forming apparatus includes at least one radio frequency channel submodule, a phased array submodule, and an interface module; the radio frequency channel submodule converts a baseband signal received by the interface module from the outside into a radio frequency signal and sends the radio frequency signal to the phased array submodule, and converts the radio frequency signal received by the phased array submodule into a baseband signal, where the baseband signal is output to the outside by using the interface module; the phased array submodule performs beam forming on the radio frequency signal sent by the radio frequency channel submodule and then sends, by using an antenna, the radio frequency signal obtained after the beam forming, and sends data received from the antenna to the radio frequency channel submodule; the interface module transmits the baseband signal between the radio frequency channel submodule and an external baseband data unit, and is configured for multi-module expansion connection to another apparatus. According to the present invention, joining of multi-beam forming apparatuses in a base station can be implemented by providing a modular multi-beam forming apparatus. |
