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,
