The amplifier module, including multiple amplifier units with different gains, amplifies an input signal. The control unit enables at least one of the amplifier units according to a gain control signal, wherein the enabled at least one amplifier unit generates an output RF signal in response to the input signal. The mixer coupled with each amplifier unit in series down-converts the output RF signal into an IF signal according to a local oscillation frequency. The IF amplifier having a variable gain is coupled to the mixer for amplifying the IF signal to an output signal according to the gain control signal. The control unit obtains the gain control signal according to the output signal and a reference signal.
