Datum M7LT L-Band Mesh Sat-Terminal

Datum Systems M7LT Mesh L-Band Satellite Terminal

The Datum Systems M7LT Mesh is a compact, high-efficiency L-Band satellite terminal designed for SCPC Mesh, Point-to-Multipoint, and Hybrid Mesh/PtMP network architectures. Operating from 950–2150 MHz, it integrates internal BUC and LNB power supplies with a high-stability 10 MHz OCXO reference. Supporting one transmit carrier and up to 16 individual receive carriers in a single 1RU chassis, the M7LT Mesh delivers ultra-low latency, fast carrier acquisition, and flexible bandwidth allocation for enterprise, cellular backhaul, and on-the-move SATCOM networks.
