초록
A radio frequency receiver of the present invention removes out-of-band jamming signals and interference signals without SAW filters. The radio frequency receiver includes: a low noise amplifier amplifying a signal received through an antenna; a second order intermodulation cancellation unit removing second order intermodulation caused by an out-of-band jamming or interference signal included in the signal output from the low noise amplifier; a passive mixer unit converting a frequency of the signal output from the second order intermodulation cancellation unit; and a low pass filter unit removing an out-of-band jamming or interference signal included in the signal output from the passive mixer unit and delivering the signal with the out-of-band jamming or interference signal removed therefrom to a transimpedance amplifier.
