a method and apparatus for controlling a sar in a mobile communication terminal . the sar is controlled by adjusting a transmission power of a mobile communication terminal . the method for controlling the sar in a mobile terminal includes the steps of checking a user - selected sar control mode of the mobile terminal , setting a code value corresponding to a transmission power of the rf signal to a gain of the amplifier , wherein the code value is set to a first code value when the sar control mode is a safe mode , or is set to a second code value when the sar control mode is a normal mode , and amplifying the rf signal according to the gain of the amplifier , such that it controls a transmission power of an rf signal by controlling a gain of an amplifier amplifying the rf signal .
