Patent ID: 7383018

Claim:
An outdoor unit of a satellite television ground system comprising: converter circuitry operative to receive a first satellite television signal and a second satellite television signal and to block downconvert the first satellite television signal and the second satellite television signal; coarse tuning circuitry in communication with said converter circuitry and operative to coarse tune the first block downconverted satellite television signal and the second block downconverted television signal, wherein said coarse tuning circuitry comprises: a first frequency synthesizer in communication with said oscillator circuitry and operative to generate a first synthesized signal; a first signal combiner in communication with said first frequency synthesizer and said converter circuitry, said first signal combiner operative to receive said first block downconverted signal from said converter circuitry and said first synthesized signal from said first frequency synthesizer, and to produce a first combined signal; a filter in communication with said first signal combiner and operative to receive said first combined signal pass a first coarse tuned signal there from; a second frequency synthesizer in communication with said oscillator circuitry and operative to generate a second synthesized signal; a second signal combiner in communication with said second frequency synthesizer and said converter circuitry, said second signal combiner operative to receive said second block downconverted signal from said converter circuitry and said second synthesized signal from said second frequency synthesizer, and to produce a second combined signal; and a second filter in communication with said second signal combiner and operative to receive said second combined signal and pass a second coarse tuned signal there from; and oscillator circuitry in communication with said converter circuitry and said coarse tuning circuitry, and operative to generate and provide an oscillator signal to said converter circuitry for block downconverting the first satellite television signal, and to generate and provide the oscillator signal to said coarse tuning circuitry for coarse tuning the first downconverted satellite television signal.
