Abstract
A double conversion RF tuner includes an up-conversion unit and a down-conversion unit. The up-conversion unit up converts a received radio frequency (RF) signal corresponding to a first frequency band to a first intermediate frequency (IF) signal and up-converts the received RF signal corresponding to a second frequency band higher than the first frequency band to a second IF frequency. The down conversion unit down converts one of the first and second IF signals outputted from the up-conversion unit to a final IF signal.
