Novel smart antenna coupling calibration network containing RCU (remote control unit) control circuit

The utility model discloses a novel smart antenna coupling calibration network containing an RCU (remote control unit) control circuit. The novel smart antenna coupling calibration network comprises a directional coupler, a power divider and the RCU control circuit; the novel smart antenna coupling calibration network also comprises an LC (Inductance and Capacitance) circuit; a capacitor end of the LC circuit is connected with the power divider, an inductor end is connected with the RCU control circuit, and a third end is connected with a radio frequency calibration end of a base station; therefore, the integration framework of the coupling calibration network and the RCU control circuit can be realized. With the adoption of the novel smart antenna coupling calibration network, the design method that the input end of the RCU control circuit is integrated with the calibration end of the coupling calibration network is adopted, so that the building cost of the base station can be effectively reduced; meanwhile, by additionally arranging a branching unit, the independent calibration in two communication systems can be supported; in addition, the novel smart antenna coupling calibration network also has the characteristics of reasonable structure and superior electric performance and the like, so that the application prospect is broad.
