Abstract: PURPOSE:To further elevate the S/N ratio by making the high frequency noise component in the output signal flow into the ground point through the variable impedance circuit in case when the level of the FM intermediate frequency input has been remarkably lowered, by use of the variable impedance circuit. CONSTITUTION:No.14 terminal and No.15 terminal of the semiconductor integrated circuit 200 are connected to No.4 terminal and No.3 terminal through the capacities C24, C25, and said No.3 terminal and No.4 terminal are connected to the first variable impedance circuit 61 and the second variable impedance circuit 62, respectively. And when the level of the FM intermediate frequency input signal has been remarkably lowered, a collector current of the transistor Q24 increases, and the base- emitter forward direction voltage VBE of the transistors Q25, Q26 connected to the  diode rises up. As a result, the transistors Q20, Q21 in the first variable impedance  circuit, and the transistors Q22, Q23 in the second variable impedance circuit 62  increase the continuity, and therefore the emitter input resistance of each transistor  is lowered.
