Abstract
Systems and methods are provided for selecting data from intermediate frequency signals, corresponding to received signals (e.g., satellite signals) carrying modulated data, using digital channelizer switches. An example digital channelizer switch may comprise a plurality of high speed analog-to-digital converters configured to digitize the intermediate frequency signals; a plurality of digital channelizers configured to digitally tune data from the digitized intermediate frequency signals; a multiplexer configured to select one or more digitized intermediate frequency signal generated by the plurality of high speed analog-to-digital converters as inputs to the plurality of digital channelizers; and a high speed digital-to-analog converter configured to generate an analog output signal using digitally tuned data by the digital channelizer, from at least one digitized intermediate frequency signal.
