Abstract: The utility model provides a small-sized active antenna feeder system. The system comprises a casing, a control management module, an interface module, a radio-frequency signal processing module, an amplitude-phase control adjustable module and a radiating antenna module, wherein the interface module is in communication connection with the control management module; the radio-frequency signal processing module is in communication connection with the control management module and the interface module; the amplitude-phase control adjustable module is in communication connection with the control management module; and the radiating antenna module is in communication connection with the radio-frequency signal processing module and the amplitude-phase control adjustable module. According to the small-sized active antenna feeder system, a miniaturized radio-frequency signal processing module and a miniaturized base station antenna are directly designed in an integrative way, a fiber interface is also provided, or the fiber interface is directly connected with a baseband processing module, and the ideal targets of an integrative base station antenna system and a base station without a machine room are realized. The space is saved, the arrangement cost is also lowered, and the networking efficiency is enhanced. Meanwhile, connecting components and cables are reduced, so that the loss of the total system is little.
