1. An integrated circuit comprising:
a first switch;
a second switch; and
an amplifier electrically connected between the first switch and the second switch; wherein
an RF signal path passes through first switch, the amplifier, and the second switch in this order; and
the integrated circuit includes:
at least one input terminal and at least one output terminal that are to be connected to each other outside of the integrated circuit between the first switch and the amplifier with a component disposed outside of the integrated circuit and connected between the first switch and the amplifier, or
at least one input terminal and at least one output terminal that are to be connected to each other outside of the integrated circuit between the amplifier and the second switch with a component disposed outside of the integrated circuit and connected between the amplifier and the second switch; and
in a top view of the integrated circuit, a first region of the first switch, a second region of the amplifier, and a third region of the second switch are disposed on a straight line such that a virtual straight line connects any point of the first region, any point of the second region, and any point of the second region in this order.
