Overview
NGMC-101 Enigma is a combining (full fan-in) Extended L-band Matrix (850-2450MHz), 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.
–5dB to +5dB variable gain is provided and settable per input. Minimal impact from failure with hot-swap single input and output RF cards, dual redundant power supplies, CPU’s and fans.
The new 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 optimize 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.
A variety of impedances and connector types are available.
