PURPOSE: An RF-signal-processing circuit is provided not to enable an analog demodulator and a digital demodulator to influence each other on operation. CONSTITUTION: An analog demodulator(46) receives an IF signal outputted from a signal selection unit. The analog demodulator demodulates the received IF signal. The analog demodulator outputs an analog signal. The analog demodulator generates an automatic gain control signal. A LPF(Low Pass Filter) is arranged on a route that the automatic gain control signal is transmitted from the analog demodulator to an RF amplifier.
