Abstract
A radio frequency (RF) receiver and a method of receiving an RF signal are provided. The RF receiver includes a low-noise amplifying unit which amplifies a received signal while restricting out-of-band interference of the received signal, a sampling unit which performs sampling to convert the amplified signal to a discrete time domain signal, a frequency translation unit which down-converts the discrete time domain signal into a frequency band that enables the discrete time domain signal to be converted into a digital signal and restricts interference from a frequency within an aliasing band according to a sampling frequency, an anti-aliasing filtering unit which prevents aliasing from the down-converted signal, a clock unit which provides the sampling unit, the frequency translation unit, and the anti-aliasing filtering unit with sampling frequencies, and an analog-digital-converter which converts the converted signal into the digital signal.
