Abstract

See full text

A phase control method in the present disclosure includes dividing, by a power divider, the high frequency current into at least two current branches, and separately feeding the at least two current branches into corresponding radio frequency input ports on a digital phase shifter, determining, by the switch controller according to the digital control flow, radio frequency paths that are in the digital phase shifter and for the at least two current branches fed into the digital phase shifter, and controlling the drive voltage to act on the digital phase shifter, and separately establishing, by the digital phase shifter according to the drive voltage and for the at least two current branches, radio frequency paths for currents to flow through, and controlling duration of phase delays for the at least two current branches by controlling lengths of the radio frequency paths through which the at least two current branches flow.
