PURPOSE: An RF-signal-processing circuit is provided to control an amplified control operation of an amplifier which amplifies a middle frequency signal. CONSTITUTION: An IF(Intermediate Frequency) AGC(Automatic Gain Control) controller(26) transfers a control signal for controlling an amplification degree of an IF amplifier by using the information provided from a demodulator through a first node to an IF amplifier. One side of a first capacitor(C2) is connected to the first node. The other side of the first capacitor is connected to a second node.
