DMD2050E MIL-STD-188-165A Military Satellite Modem

The Comtech Radyne DMD2050E Satellite Modem is designed to comply with the widest possible range of U.S. Government and commercial standards and is compatible with the largest number of satellite modems in the industry. It is fully compliant with MIL-STD-188-165A (all terminal types), fully complies with STANAG 4486 Edition 3, the draft standard MIL-STD-188-165B, as well as the IESS‑308, IESS‑309, IESS‑310 & IESS-315 commercial standards.

Advanced Forward Error Correction

The DMD2050E provides highly advanced and bandwidth efficient forward error correction (FEC). Advanced FEC options include Low Density Parity Check (LDPC), Turbo Product Codes (TPCs) and 165B Turbo Codes. Legacy support for Viterbi, Trellis, Concatenated Viterbi Reed‑Solomon, and Sequential FEC are also included. A complete range of modulation types is supported including BPSK, QPSK, OQPSK, 8PSK, 8-QAM, 16-QAM and 16APSK.

Advanced FEC and modulation capabilities are integrated with the revolutionary DoubleTalk® Carrier-in-Carrier® bandwidth compression allowing for maximum state-of-the-art performance under all conditions. This combination of advanced technologies enables multi-dimensional optimization, allowing satellite communications users to:

  • Minimize required satellite bandwidth
  • Maximize throughput without using additional transponder resources
  • Maximize availability (margin) without using additional transponder resources
  • Enable use of a smaller BUC/HPA and/or antenna
  • Or, a combination of the above to meet specific mission needs

Adaptive Coding and Modulation (ACM)

The Radyne Comtech DMD2050E also supports Information Throughput Adaptation (ITA). Also referred to as Adaptive Coding and Modulation (ACM), ITA enables modems on each side of a point-to-point link to use the modulation and coding combination that maximizes throughput, and automatically adapts the optimum operating point as conditions (such as weather) change.

Data rates range from 2.4 kbps to 52 Mbps and symbol rates from 4.8 ksps to 30 Msps. The modem provides standard MIL‑STD‑188‑114 (EIA-530 / RS-422), and EIA-613 (HSSI) serial interfaces and 10/100/1000Base-T Gigabit Ethernet interfaces. A dual IF interface supports low IF (52‑88, 104-176 MHz), and L-Band
(950‑2000 MHz) frequency ranges.
