Abstract
An amplification circuit includes a first switching circuit that includes input terminals and first and second output terminals and that puts the second output terminal into an open state with respect to the input terminals while selectively putting the first output terminal into a state of being connected to any of the input terminals or selectively puts the second output terminal into a state of being connected to any of input terminals while putting the first output terminal into a state of being open with respect to the input terminals, a matching network that is connected to the first output terminal, an amplifier that is connected to an output side of the matching network, a second switching circuit that is connected to an output side of the amplifier, and a bypass path that electrically connects the second output terminal and an output terminal of the second switching circuit.
