Giga-tronics Announces Digital Radio Frequency Memory (DRFM) Jammer Development

Electromagnetic defense technology enhances capabilities of Gresham’s TEmS platform for advanced threat emulation in warfighter training and system testing

DRFM Jammer capability unveiled and demonstrated at 59th Annual AOC International Symposium and Convention, October 25-27, in Washington, DC

Scottsdale, AZ October 25, 2022 – Giga-tronics Incorporated (OTCQB Market: GIGA), the (“Company”) (“Giga”), unveiled an advanced Digital Radio Frequency Memory (DRFM) Real-Time Closed-Loop Radar Jammer Emulator as part of Gresham Worldwide’s (“Gresham”) portfolio of electromagnetic countermeasures, the market for which is estimated to be $865 Million and growing.

Designed using an RF System-on-a-Chip (RFSOC) architecture and an AXIe chassis enclosure, Giga-tronics’ novel DRFM Jammer solution offers best-in-class modularity, scalability, and flexibility for both lab and field-based use in open-air range testing of electromagnetic countermeasures. Coupled with its suite of advanced signal generator solutions, the Giga-tronics’ DRFM Jammer provides industry-leading emulation of enemy jammers for use in System Under Test evaluation in warfighter training, and by major defense contractors in developing robust, adaptive radar hardware and software more immune to ever-evolving electromagnetic attack. The Giga-tronics DRFM Jammer also provides a flexible testbed for evaluating the effectiveness of new jamming techniques against adversary systems.

Giga-tronics’ DRFM Jammer is part of the company’s comprehensive threat emulation system (TEmS) portfolio, pushing the boundaries of RF threat simulation and rapidly becoming the technology of choice among antenna, radar and jammer product developers. With Giga-tronics’ full suite of RF solutions, including real-time adaptive emulation, coherent multi-channel capture, analysis and playback, and PDW-to-RF generation, Giga’s DRFM Jammer allows for a complete set of tools for personnel training in labs, chambers, and on ranges as well as electromagnetic countermeasures product development and testing.

“The proliferation of advanced active electromagnetic countermeasures and defense industry needs for more advanced integrated solutions drove the development of our state-of-the-art DRFM Jammer,” offered Armand Pantalone, Chief Technology Officer of Giga-tronics. “The ability to offer an advanced ‘jammer out-of-the-box’ is novel and unique. Our use of RF System on a Chip (RFSOC) based open architecture hardware and embedded software designs enables customers to use this DRFM Jammer as a building block with their threat libraries and adds functionality to our TEmS product platform to emulate emerging threats in troop training and equipment testing.”

Jonathan Read, Chief Executive Officer of Giga-tronics, added, “Rising global tensions have prompted many governments to invest more in defense capabilities and electromagnetic countermeasures account for an increasing proportion of that investment. As we continually learn more about the electromagnetic spectrum capabilities of adversaries, Gresham remains committed to developing and delivering innovative solutions that enable our customers to better prepare warfighters and the equipment available to them that protect military forces and civilian lives from attack.”

Gresham introduced and demonstrated the DRFM Jammer capability in October at the 59th Annual AOC International Symposium and Convention, an industry-leading, three-day event which brought together nearly 2,000 professionals from 30+ countries spanning industry, military and government sectors.
