Abstract

PURPOSE: To improve the leading edge characteristic at power save release by suppressing a deviation in a bias level of an output signal.
CONSTITUTION: The amplifier is provided with an output transistor(TR) 2 and an output terminal of the output TR 2 is connected to a load circuit 6 via a capacitive coupling circuit 4. Moreover, a semiconductor switch element 10 is provided in a circuit 8 energizing an operating DC current to the output TR 2. Then at the intermittent reception release, a power save control signal transferring an active region of the semiconductor switch 10 to the cut-off state is applied to the semiconductor switch element 10 in the circuit 8 energizing the output TR 2. The semiconductor switch 10 supplies a leakage current depending on the cut-off state to the output TR 2. Thus, even when the amplifier is set in the power save state, a signal average DC voltage level almost required for the load circuit 6 is generated at an output terminal of the output TR 2.
