Abstract
A radio frequency circuit includes a switching circuit, an amplifying circuit, and a potential stabilizing circuit. The switching circuit includes a switch disposed on a path connecting a first terminal, to which a radio-frequency signal is input, to a second terminal, from which the radio-frequency signal is output, a first capacitor disposed between the first terminal and the switch, and a second capacitor disposed between the switch and the second terminal. The amplifying circuit includes an amplifier disposed between the switching circuit and the second terminal, a third capacitor disposed between the switching circuit and the amplifier, and a fourth capacitor disposed between the amplifier and the second terminal. The potential stabilizing circuit is connected to a first node which is located between the switching circuit and the amplifying circuit and which is located on a path connecting the second capacitor to the third capacitor.
