​

What to consider when selecting a digitizer for Satellite Communication applications

  • Wide analog bandwidth for flexibility in selecting the IF bandwidth

  • High speed sampling needed for signal bandwidth and low noise aliasing

  • High spurious free dynamic range to resolve low level signals

  • Digital down converter to reduce the sample frequency and increase signal to noise ratio

  • Decimation filtering for improved ENOB

  • Open FPGA for custom real-time digital signal processing

  • High data transfer rate is needed to support fast post-processing

  • Global Navigation Satellite System (GNSS) use L-band up to 1.6 GHz. This can be recorded by direct sampling and avoiding analog mixers.
