Abstract
A first amplifier is connected between an input terminal and an output terminal. A first junction point is located between the input terminal and an input of the first amplifier. A second junction point is located between the output terminal and an output of the first amplifier. A second amplifier is connected in parallel with the first amplifier, between the first junction point and the second junction point. A third junction point is located between an output of the second amplifier and the second junction point. A first capacitor and a switch are connected in series between the third junction point and ground. The second junction point is the lowest impedance point along a power amplification path that includes the input terminal, the first amplifier, and the output terminal. The switch is turned off/on when the second/first amplifier is turned on.
