Extreme SWaP Software Defined Radio
SDR M OEM board

The SDR-M is an ultra-light, ultra-compact software defined IP mesh radio, composed of an enclosed single board.


Refining the success of DTC's small-form factor SDRs, the SDR-M is SDR-C small-form factor SDR, the SDR-M is employable both as an integrated component part of UxVs and larger systems, and as a standalone radio used in primarily body-worn concealment scenarios.

Weighing just 60g, consuming only 3W of input power but delivering 200mW of output power, the SDR-M is ideal for size and weight critical UxV applications, offering the SWaP of a bare-board solution but housed in a practical, robust enclosure.

The SDR-M is available in OEM (bare board) format for platform integration as the D196x OEM board.

  • MeshUltra™, MIMO and Standard IP Mesh capability
  • Interference Avoidance Scheme (IAS)
  • Transmitter / Receiver / Transceiver
  • Interlink connection across different bearers
  • AES128/256 COMSEC



High Tech Simplicity

The SDR-M combines DTC's most cutting-edge technology, including the MeshUltra-XTM waveform allowing 144 nodes to operate in just 1.25MHz of bandwidth, with the practicality of a simple board self-contained solution.

Feature Rich

The SDR-M contains DTC’s most advanced performance features including the MeshUltra-XTM high capacity in narrowband waveform and the cognitive IAS (Interference Avoidance Scheme).


Ultra Compact

Completely self-contained in dimensions of just 54mm x 50mm and weighing only 60g, the SDR-M has been designed for compatibility to even the most demanding of integration and installation requirements. High-strength horizontal mounting points with no external protrusions combined with top and bottom equidistant vertical connectors make installation of the SDR-M as space-efficient as possible.
