The all-new CDM-650

26 August 2021


Comtech’s new CDM-650 Satellite Modem leverages the heritage and feature set by the company’s SLM- 5650B/C, CDM-625A and CDM-425 modems – the company says - which have been adopted and deployed globally to support government and commercial applications.

The CDM-650 was purpose-built for secure government and military networks, and is suited for fixed location, on-the-pause and communications on-the-move applications. Furthermore, the product features turbo product codes, three LDPC code families, VersaFEC-2 high performance LDPC short and long block forward error correction and a range of modulation, including BPSK, QPSK, OQPSK, 8PSK, 8-QAM and 16-QAM.

By employing the combination of what Comtech describes as “state-of-the-art forward error correction and modulation techniques”, the CDM-650 can optimise satellite transponder bandwidth usage.

“We are pleased to introduce the new CDM-650 Satellite Modem to address the needs of foreign govern¬ment and military entities,” says Fred Kornberg, chairman of the board and chief executive officer of Comtech. “The advanced feature set available in the CDM-650 provides the per¬formance, reliability and scalability needed for secure and mission-criti¬cal networks.”
