The NGM-21 Series are L-band Switch Matrices / Routers that operate from 850 MHz to 2150 MHz. It has 32 Inputs x 32 Outputs with 50 ohm SMA/BNC connectors or 75 ohm F Type/BNC connectors. This switching system has a compression point of 5 dBm, return loss under 16 dB and an isolation of 70 dB. The Matrix has been designed such that there is one card associated with each input and each output &ndash so failure of a card only affects one channel. For broadcasters, satellite operators and the defence sector, this provides exceptional resilience. The design offers rugged dual redundant power supplies with simple front access, enhanced CPU change-out, hot-swap fans and new card connectors. Web Browser Interface is standard on an NGM-21.
