Datum M7LT L-Band Satellite Terminal

Datum Systems M7LT L-Band Satellite Terminal

The Datum Systems M7LT is a high-efficiency L-Band satellite terminal designed for professional fixed, mobile, and on-the-move SATCOM applications. Operating from 950–2150 MHz, it integrates internal BUC and LNB power supplies with a high-stability 10 MHz OCXO reference. Supporting advanced FlexLDPC, ACM, and Smart Carrier Cancelling, the M7LT delivers ultra-low latency, fast acquisition, and data rates up to 59.04 Mbps in a compact 1RU rack-mount platform.
