Apparatus and method for receiving RF signal

The invention proposes an RF receiver implementation removes the SAW filter. Receiver of the present invention, the received signal of sikimyeo suppress the interference of the out-of-band low noise amplifier unit for amplifying the received signal; A sampling unit that performs sampling for converting the amplified received signal into a discrete time domain; The down-converting the sampled signal to convert a predetermined frequency band available to a digital signal, and the frequency converter to suppress the interference on the frequency of the aliasing band according to the sampling frequency; An anti-aliasing filter unit for removing aliasing to the converted signal; The sampling unit, the frequency converting unit and a clock unit to provide a sampling frequency for the anti-aliasing filtering unit; And including analog-to-digital converter for converting the converted signal into a digital signal, it is possible to provide a RF receiver, increase the degree of integration. SAW filter, a receiver, a low noise amplifier, FIR filters, a discrete-time domain,
