PURPOSE: An RF signal processing circuit is provided to prevent performance characteristic from demoralizing due to a click signal generated in a digital demodulator. CONSTITUTION: A signal selecting unit(200) transmits a signal of desired band among an RF signal inputted through an antenna. A demodulator(240) demodulates a signal provided in a signal selecting unit by using a clock signal generated inside. A trap filter unit(300) prevents electric wave of undesired frequency clock signal inside the signal selecting unit and inside the demodulator.
