    摘要: There is provided a small size phase shifter which can shift a phase by 180 degrees wherein the accuracy of preset phase is less dependent on frequency. The phase shifter comprises first to fourth switches provided between a first line pair and a second line pair. By turning the first and second switches ON and the third and fourth switches OFF, a signal inputted to the first line pair is outputted from the second line pair in phase. By turning the first and second switches OFF and the third and fourth switches ON, a signal inputted to the first line pair is outputted from the second line pair out of phase. A small-size phase shifter which has the accuracy of preset phase less dependent on frequency can then be obtained.
