Abstract: PURPOSE: A method for eliminating mismatch in wireless communication system, a receiver thereof, and a LNA(Low Noise Amplifier) thereof are provided to offer a LNA to eliminate the mismatch in an input unit of the receiver. CONSTITUTION: If an input signal is wideband signal, a controller performs the common bias control for eliminating mismatch in LNA(703,705). If the input signal is narrowband signal, the controller performs independent bias control for improving the linearity in LNA(707). A receiver receives a signal of which the mismatch or adjacent channel interference is eliminated(709).
