Abstract
According to one embodiment of the present invention, there is provided a high-frequency switching circuit including a first differential line and third line. The differential line includes a first line configured to have one end and an other end, a second line configured to have one end and an other end and a first switch configured to switch electrical connection between the one ends of the first and second lines. The differential line receives or outputs differential signals by the other ends of the first and second lines. The third line is configured to be electromagnetically coupled with the first differential line when the first switch is turned on. The first switch is arranged at a position where an electrical length from the other end of the first line and an electrical length from the other end of the second line are approximately equal.
