Phase shifter having power dividing function

摘要

Disclosed is a phase shifter having a power dividing function. The phase shifter includes: an input port (10) for receiving a radio frequency (RF) signal; a power dividing unit (13) for dividing the RF signal into a first divided signal of which phase is to be varied and a second divided signal having a fixed phase value; a first output port (11) for outputting the second divided signal having the fixed phase value; a phase shift unit (15) for dividing the first divided signal into a third divided signal and a fourth divided signal wherein the third divided signal and the fourth divided signal move in opposite directions; a phase delay unit (17A,17B) for shifting phase of the third divided signal and the fourth divided signal based on a difference in a path length of the third divided signal and the fourth divided signal, to thereby generate phase-shifted signals; and at least two second output ports (12A,12B,12C,12D) connected to the phase delay unit, for outputting the phase-shifted signals.
