ROVER SATCOM - Ku RDC System 12-2020

MAIN BENEFITS

  • RF Switch protected against Mains Power Failure
  • Simultaneously Supply of: Low & High Band and Vert & Horiz Polarity via RF coax or opt. Optic Fiber TX
  • Fully redundant PSU and BDCs
  • Front panel functional Block diagram with related LED & RF monitor Port
  • Completely Hot swap, with minimum service interruption, thanks to front plug-in modules

MAIN FEATURES

  • All Sat Band supported: S, X, Ku, Ka on request
  • Very Low Phase noise and high frequency accuracy, high P1 dB and IP3
  • Raccomended for very low Symbol Rate carriers
  • Suggested for Professional applications, Teleports, Broadcast & Military
  • Display, SNMP, WEB Controller, with Alarms & Logger
  • The “Ku RDC System” is a compact and comprehensively Down Converter System, fully redundant, fully remote controllable, can supply simultaneously Low & High Band, Vertical & Horizontal (or Circular Left & Right) polarity via RF COAX or opt. Optic Fiber.
  • The RF Redundancy Switch are protected against power failure thanks to Ultracap Technology.
  • Thanks to 5 front plug-in module, all parts can be HOT SWAPPED with minimum services interruptions, each module has an indipendent Microcontroller and Memory to clone the New Module installed.
  • The “Ku RDC System” is controllable via Local display or remotely via WEB GUI & SNMP; through N. 2 Ethernet port and thanks to N. 2 SFP Slot can be connected/controlled also via fiber optic.
