Abstract
An apparatus for receiving signals in a radio frequency system includes a low noise amplifier that amplifies and filters a signal received from an antenna; a first frequency mixer that mixes the signal output from the low noise amplifier and an oscillation signal supplied from a local oscillator to create a signal of an intermediate frequency; a second frequency mixer that mixes the signal of an intermediate frequency and one or more oscillation signals that have an offset added to have different frequency channels, which have a predetermined bandwidth, to create one or more signals of a baseband frequency; a channel selection filter that divides one or more signals generated in the second frequency mixer into one or more different frequency channels having a predetermined bandwidth using the offset; and an amplifier that amplifies the signals that have been filtered in the channel selection filter.
