Satellite Communication

Overview

Satellite communication has allowed for advances in global navigation, weather, mobile phones, radio, and television.

The Up-Link and Down-Link segments of Satellite’s contain RF frequencies up to approximately 7 GHz (L, S, and C-Bands) and for the 5G mobile/base station configurations up to 6 GHz and in the milli-meter wave bands (24 to 86 GHz).

On the receive side a weak analog signal is amplified and down converted to an Intermediate Frequency (IF) which is then fed into a high-performance digitizer for efficient processing.

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.
