Original Abstract Submitted

An amplifier circuit includes a high frequency input terminal and a high frequency output terminal, amplifiers, an output transformer having an input-side coil and an output-side coil, inductors, and a bypass capacitor. An output end of the amplifier is connected to one end of the input-side coil and one end of the inductor. An output end of the amplifier is connected to the other end of the input-side coil and one end of the inductor. The other end of the inductor, the other end of the inductor, and one end of the bypass capacitor are connected to a midpoint of the input-side coil. One end of the output-side coil is connected to the high frequency output terminal.
