Digital IF for MILSATCOM Terminals
A compelling case has been made for transitioning MILitary SATellite COMmunications (MILSATCOM) terminal architectures from conventional analog IF (Intermediate Frequency) formats to newer more capable digital IF (Intermediate Format) systems. Digital IF has been shown to offer clear and substantial advantages in all aspects of MILSATCOM terminal activity and operations, from development to deployment, from signal quality to cost and footprint, from Control, Monitoring and Alarm (CMA) systems to Built-In Test (BIT) features. Significant performance, cost and footprint advantages can be realized in terminals of all sizes, large, medium and small. A Digital IF initiative can yield early and disproportionately high yields on a modest investment because no new technology is required to begin the migration to all-digital MILSATCOM terminals.
