Abstract: PURPOSE: An apparatus for transmitting/receiving an RF signal in a wireless communication system is provided to extend a signal reach distance by using a high-gain transmission power output device and an external LNA(Low Noise Amplifier) at a long distance. CONSTITUTION: External amplifiers(111,117) amplify required power levels which request signals to be transmitted, and a transmission selector(116) outputs the amplified signals to an antenna. A mode selector(114) compares the power level of the reception signal provided from a reception device with a predetermined power level. The mode selector generates a mode signal for determining whether or not the external amplifiers are activated.

Abstract: An AGC(Automatic Gain Control) method having variable gain control intervals and a device thereof are provided to perform a rough gain control loop in a wireless communication system having multiple antennas, and additionally conduct a detailed gain control loop for receiving signals passing through a gain control process, thereby obtaining stable gains. RF(Radio Frequency) receivers(110) receive a plurality of the first signals through plural antennas, and perform gain control for the received first signals to output the first signals as a plurality of the second signals. A signal saturation sensor(400) outputs a saturated state determination value if the number of the second signals larger than a threshold value is more than a predetermined number. A gain controller(300) detects one power by comparing power of the second signals, and outputs the detected power and a gain determination value determined on the basis of the saturated state determination value to the RF receivers(110).
