ABSTRACT:
A multi-tuner system includes a first conversion tuner that converts a first RF signal among a plurality of RF signals received from an antenna into a first IF signal using a first conversion mode, the first RF signal corresponding to a first selected channel; and a second conversion tuner that converts a second RF signal among the RF signals into a second IF signal using a second conversion mode, the second RF signal corresponding to a second selected channel. Any IF interference between the tuners is eliminated, and the tuners can be fabricated into a single module.
