1. A device for processing satellite signals comprising:

  • a first amplifier chain that receives a first RF signal;

    a second amplifier chain that receives a second RF signal;

    a first bandpass filter coupled to the output of the first amplifier chain;

    a second bandpass filter coupled to the output of the second amplifier chain;

    a matrix switch coupled to the outputs of the first bandpass filter and the second bandpass filter;

    a frequency converter block coupled to the outputs of the matrix switch that outputs frequency converted signals;

    a combiner coupled to the output of matrix switch that combines the frequency converted signals and produces a frequency stacked IF output wherein a single frequency conversion is performed between the RF input signals and the frequency stacked IF output;

    a first output filter coupled to an output of the frequency converter block for selecting a first set of frequencies;

    a second output filter coupled to another output of the frequency converter block for selecting a second set of frequencies wherein the outputs of first output filter and the second output filter are coupled to the inputs of the combiner.
