Integrated multiple tuner architectures and associated methods are disclosed that utilize frequency isolated local oscillators (LO). These architectures utilize dividers and multipliers within the signal paths for the local oscillator mixing signals to reduce interference among the multiple local oscillators...http://www.google.co.uk/patents/US7447491?utm_source=gb-gplus-sharePatent US7447491 - Multi-tuner integrated circuit architecture utilizing frequency isolated local oscillators and associated method
