摘要
A variable phase shift circuit has a phase shifter including a first port and a second port; a through path including a first port and a second port; a first switch including a first common port and configured to select the first port of the phase shifter or the first port of the through path and to connect the first port or the first port to the first common port; and a second switch including a second common port and configured to select the second port of the phase shifter or the second port of the through path and to connect the second port or the second port to the second common port. Phase shift amounts between the first common port and the second common port are switched in accordance with selections made by the first switch and the second switch.
