PURPOSE: An RF-signal processing circuit is provided to prevent operation characteristics from demoralizing due to a clock signal which is generated from a digital demodulator. CONSTITUTION: An RF signal processing circuit includes a signal selecting unit(200), a demodulator(400), and a trap filter unit(300). The signal selecting unit is for transmitting a signal of bandwidth which desires among an RF signals inputted through an antenna(ANT). The demodulator is for demodulating a signal which is provided from the signal selecting unit by using a clock signal generated from inside. The trap filter unit is for preventing a clock signal generated from inside of the demodulator from transmitted to the signal selecting unit.
