Abstract: An apparatus and a method for receiving a signal by using an RF filter bank are provided to minimize the interference from the outside by using an RF filter bank placed at an RF front-end. An RF broadband filter(11) removes signals except the signals of the preset RF bandwidth among signals received at an antenna, and an RF filter bank(12) filters an RF signal, which passes through the RF wideband filter, by a frequency channel filter. A frequency down-converting unit(10) noise-amplifies the passing RF signal, and removes a harmonic signal which occurs during the amplification. The frequency down-converting unit mixes the RF signal with a local oscillating signal to convert the mixed signal into an IF signal.
