Cable receiver having in-band and out-of-band tuners

摘要

A cable television receiver includes in-band and out-of-band tuners integrated on a single IC. A mode controller determines whether an out-of-band signal is being received and powers the out-of-band tuner off when no out-of-band signal is present. A signal divider divides the signals between the in-band and out-of-band tuners and may be an asymmetric coupler in order to provide a higher power signal to the in-band tuner and a lower power signal to the out-of-band tuner.
