The present invention relates to a digital phase shifter. The phase shifter of the present invention comprises: a signal distribution unit having a plurality of channels to distribute an input signal with a determined ratio and output the input signal after delaying for a preset locked phase; a variable phase unit for outputting a signal outputted from the signal distribution unit by linearly delaying a phase of the signal; and an output unit for amplifying and adjusting a signal outputted in the variable phase unit, and outputting the signal through an antenna. |
