Abstract
An apparatus and method for receiving RF signals in a RF communication system are provided. The apparatus for receiving RF signals comprises a pre-processing unit for bandpass-filtering a signal received through an external antenna with a predetermined bandwidth and extracting a RF input signal having a desired frequency; a mixing unit for mixing the RF input signal provided from the pre-processing unit with a local oscillation signal having the same frequency as the RF input signal and generating a desired baseband signal; a noise-free-signal amplifying unit for shifting the desired baseband signal to a band that is free of effects due to 1/f noise, amplifying the shifted baseband signal, and re-shifting the amplified signal to the baseband; and a baseband processing unit for selecting a desired channel signal from the amplified baseband signal to be provided from the noise-free-signal amplifying unit and amplifying the selected signal.
