A phase shifter includes a first signal path in which a first unit is disposed to advance a phase of a signal; a second signal path in which a second unit with no shunt capacitor is disposed to change the phase of the signal such that the changed phase is delayed than the advanced phase by the first unit; and a switch section configured to switch between the first signal path and said second signal path. The first unit comprises a filter, and the second unit is a transmission line. |
