The bypass circuit includes a first port connected to the input terminal, a second port connected to the output port of the amplifier, a switch, a capacitor, and a second inductor. The switch is connected in series between the first and second ports. The capacitor is connected in series to the switch between the first and second ports. The second inductor is connected in series to the switch and the capacitor between the first and second ports. The amplifying circuit does not reduce power of a signal drastically even when the signal passes through the bypass circuit, as compared to passing through the amplifier, thus maintaining a profile of a propagation property unchanged and provide preferable transmission quality.
