High Speed Signal Path

• Objective
• To enable significantly higher revenue per kg in
  orbit for satellite operators!
• Elimination of RF downconverters in L-Band
  payloads using ADCs with Ultra wide input
  bandwidth.
• Highest possible ENOB to minimize the ADC
  resolution to the minimum necessary nb of bits.
• Increased number of FDMA channels in Nyquist
  zone, thus increased revenue per kg for satellite
  operators.
• Advanced Space grade Package design to minimize
  lead inductance and resistance, matched impedance
  lines in signal path, planes on the supply rails
  to minimize noise induced by digital switching.
  Improved thermal characteristics.

digitised early in the signal path. 41 MUX and
serial output minimises ADC pin count and thus
nb of interconnects ADC addressing through
through CS and decoder minimises consumption No
