CIRCUIT FOR ATTENUATING RECEIVING SIGNAL OF MOBILE COMMUNICATION TERMINAL

PURPOSE: A circuit for attenuating a receiving signal of a mobile communication terminal is provided for decreasing a receiving signal using a common amplification and attenuating operation of an electric field effect transistor and decreasing the level of a receiving signal. CONSTITUTION: When a receiving signal is inputted into a receiver of a mobile communication terminal, a first condenser(100) transmits an alternating current component from which a direct current component is removed. A second condenser(200) removes a noise of an attenuating control signal outputted from a controller. A first switching unit(300) is turned on when an attenuating control signal from the second condenser(200) is a high signal and is turned off when the attenuating control signal is a low signal. In addition, A second switching unit(500) is turned on when an attenuating control signal from the third condenser(400) is a high signal and is turned off when the attenuating control signal is a low signal.
