ABSTRACT:
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 operating on a single integrated circuit. A multiple tuner direct-down-conversion (DDC) receiver and a multiple tuner intermediate frequency (IF) receiver are provided as example embodiments. And an example integrated multi-tuner satellite receiver is also described.
