Germany-headquartered international electronics group Rohde & Schwarz (R&S) has achieved R&S M3SR software-defined radios (SDR) delivery milestone.

The company has delivered more than 10,000 R&S M3SR SDRs to date.

Most of the units delivered so far include the R&S M3SR Series 4400 VHF / UHF radios used for line of sight (LOS) communications.

The company’s SDR is highly modular and suitable for stationary and shipborne communications. They offer secure transmission of military voice and data and support LINK11 and LINK22 transmission methods.

Designed to comply with Nato standards, it provides various system interfaces and waveforms such as standard and proprietary frequency hopping waveforms.

To keep the existing LOS communication systems up to date, it comes with an enhanced successive software update. Additionally, updates can be carried out through new hardware modules.

Rohde & Schwarz Secure Communications Division executive vice-president Hartmut Jäschke said: “By making targeted technical adjustments and enhancements, we have been able to continuously meet our customers’ needs and improve our market position.

“Our professional production and manufacturing help ensure quality at the highest level. The high reliability and technical performance of the radio is a decisive reason why our customers choose our SDRs.”

The device is manufactured and assembled in a facility in Memmingen, Germany. It is currently in use with international navies, mobile military and civil air traffic control tower.

The Memmingen production plant has a calibrated laboratory and an antenna test chamber.
