Link 11/22 Multi Link Terminal MLT 2920.

Concurrent multi link operation
Supported frequency bands of operation are HF and UHF. The DTS 2020 supplies the modulation types Conventional Link Eleven Waveform (CLEW) and Single-tone Link Eleven Waveform (SLEW) (per SPAWAR-S-850). The MLT 2920 incorporates two functional Signal Processing Controller (SPC) entities, SPC #1 and SPC #2, providing concurrent dual-channel operation for Link 22. Each embedded SPC operates independent from the other one without any restrictions.

Optimized solution in size and life cycle
The Multi Link Terminal MLT 2920 is a 2U rackmount device offering solution for space restricted vessels. All operational connectors are located on the back side. Operator performs initial set to work by service interfaces located on the front side. Product care occurs in working order without dismounting. During life cycle user benefits from Link 22 growth potential by uploading new features to the MLT 2920.
