PURPOSE: An apparatus for compensating a temperature in a mobile communication terminal installing a Bluetooth module is provided to linearly guide a nonlinear power change by suitably adjusting power levels of a low noise amplifier and a power amplifier and reducing the change of a power according to the temperature. CONSTITUTION: A temperature compensating unit(200) reads a voltage change according to a temperature change sensed through a thermistor, and outputs a temperature compensating signal according to the read voltage change. A microcomputer(100) receives the temperature compensating signal of the temperature compensating unit(200), and controls gains of a power amplifier(1) and a low noise amplifier(2) using a gain control signal corresponding to the temperature compensating signal. |
