Enigma L-band Matrix (Downlink) 32 x 32 with –5 dB to +5dB variable gain


  • Description

    NGM-101 Enigma is a distributive (full fan-out) L-band Matrix (850-2150MHz), with a module capacity of 32 inputs x 32  outputs in a 6U 19" rack enclosure.  It provides ultra resilience with single input and output cards, and can be part populated and expanded in single increments.

     –5 dB to +5dB variable gain is provided and settable per output. Minimal impact from failure with hot-swap single input and output RF cards, dual redundant power supplies, CPU’s and fans.

    The L-band matrix is used to provide flexibility in the routing of antennas to receivers or modems; to allow remote routing of satellite signals to receivers or modems; and to help optimise the use of receiving capacity. 

    Now in its 4th generation, the Enigma L-band Matrix has proved to have genuinely high performance with excellent flatness or frequency response, excellent isolation, and linearity - a truly leading edge L-band Router. The Enigma L-band Switch matrix can also be incorporated into an overall automatic redundancy Network Management System to enhance the resilience of the overall earth station equipment.

    With additional system security provided by SNMPv3, HTTPS, RCM TLS and NTP.

    A variety of impedances and connector types are available.

  • Benefits

    Key benefits

  • Applications

    Typical Applications

    • Live news & sport traffic
    • Satellite communications applications in teleport's and ground stations
    • Signal monitoring of satellite traffic
    • RF content acquisition for TVRO & IPTV head ends
    • Remote controlled unmanned satcoms sites
    • Test environment applications such as lab resource testing, net mobility testing & large scale wireless testing
  • Matrix Types

    Non blocking this means any input can be routed to any output

    Full fan-out matrix (or fully distributive or splitting matrix) any input can be routed to any output. One input can be routed to many outputs Each output can only have one input. Tends to be more RX.

    In general, our solid state (L-band) matrices are non-blocking.

  • Matrix sizes

    The Enigma Matrix has a full capacity of 32 inputs x 32 outputs, but can be supplied part-populated in single input / output increments - such as 15x25 or 32x16.  It can then be hot expanded to 32x32.  Larger systems can be made using multiple (Enigma) modules with system splitters and / or combiners – such as 32x64 or 32x128 up to a maximum of 512x512.

    We also have modules with other capacities - please see;

    Victor Matrix - Up to 16 input x 16 output (populated in increments of 4)

    Hurricane Matrix - up to 64 inputs x 64 outputs (populated by increments of 8)

    Vortex Matrix - Up to 64 inputs x 64 outputs (populated in increments of 16)

    Vulcan Matrix - Up to 128 inputs x 128 outputs (populated in increments of 8)
