An implementation example of the invention provides a phased array chip, a phased array beam scanning method and a device for shortening the time required for beam scanning alignment. The phased array chip includes a plurality of phase shifting channels, a plurality of switches and a control unit; each phase channel are respectively connected with an antenna, each switch is connected to at least one phase shift switch channel; each channel connected to the channel, phase shift at turn-on to transmit signals, and the phase shifting channels cannot transmit in shutdown when; the control unit for switching state of each switch change, spatial beamforming antenna direction signal so that the phased array chip connected with the change.
