Abstract: PURPOSE: An RF receiver and an interference wave removal method of RF signal for removing the interference wave are provided to reduce a size and a cost by removing a SAW filter added to the outside of the chip from the RF receiver. CONSTITUTION: An RF receiver includes a first low noise amplifier(120), a second low noise amplifier(130), a notch filter(140), and a combiner. The first low noise amplifier amplifies first received signal. The second low noise amplifier amplifies the second received signals. The notch filter removes the second amplified signals outputted from the second low noise amplifier. A combiner(150) authenticates the signal by combining the signal outputted from the first amplifier and outputs the signal.
