ABSTRACT:
A radio frequency (RF) filter is provided which includes a band pass filter unit and an amplifying unit. If a signal having a frequency in a first band is input, the RF filter performs band pass filtering, and if a signal having a frequency in a second band is input, the RF filter performs an amplifying process. The RF filter can be used for various RF signal processing devices, such as digital broadcast receiving tuners.
