Comtech Radyne DMD50 Advanced Universal Satellite Modem

DMD50 Advanced Universal Satellite Modem

The Comtech Radyne DMD50 Advanced Universal Satellite Modem supports a multitude of modulation settings such as BPSK, QPSK, OQPSK, 8PSK and 16QAM Operation. The wide variety of options available for the Comtech Radyne DMD50 Advanced Universal Satellite Modem make this unit an excellent choice for government organizations and military forces that require open network topology operation. 

The DMD50 Universal Satellite Modem breaks new ground in flexibility, operation and cost. With standards including IESS-308, IESS-309, IESS-310, IESS–315 & DVB-S, and covering data rates up to 52 Mbps, this 1RU duplex modem covers many satellite IP, telecom, video and Internet applications.

The DMD50 provides highly advanced and bandwidth-efficient forward error correction (FEC). Advanced FEC options include Turbo Product Code (TPC) and Low Density Parity Check (LDPC). 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, and 16-QAM. 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

Data Rate Options 

Data rates range from 2.4 kbps to 52 Mbps and symbol rates range from 4.8 ksps to 30 Msps. The modem provides a standard EIA-530 / RS-422 serial interface. It can optionally be configured with EIA-613 (HSSI), G.703 (T1/E1/T2/E2 & T3/E3), DVB ASI/SPI and 10/100/1000Base-T Ethernet interfaces. Drop & insert functionality is supported on the G.703 interface. A dual IF interface supports low IF (50-90, 100-180 MHz), and L-Band (950-2050 MHz) frequency ranges. Cost-effective, ultra-high reliable systems are enabled in conjunction with the RCS-11 1:1 redundancy switch, and/or the RCS-20 M:N redundancy switch.
