Reactive RF jamming systems

FPGA-based reactive jammers for counter-UAS and telecom denial

The Defender family is a line of FPGA-based reactive jammers that detect a threat transmission and respond within microseconds, concentrating power on the active frequency instead of broadcasting continuously across the whole band. Every system covers 20-8000 MHz and is configured per project for counter-UAS, telecom denial, or facility protection.

Choose a Defender system

Two platforms built on one FPGA-based reactive architecture: the scalable Modular series and the self-contained Manpack.

What makes Defender different

Reactive detection and jamming run as parallel pipelines in FPGA hardware, giving a response time of 18 µs (semi-reactive) / 36 µs (reactive) — fast enough to follow frequency-hopping drone links that defeat conventional VCO and DDS jammers. Active, semi-reactive and reactive modes can be mixed across different frequency ranges simultaneously, and every mission profile is software-defined and field-reprogrammable through Leo control software — no factory return required.

Applications

Counter-UAS / counter-drone — defeats FPV and frequency-hopping (FHSS) drone control and video links. Telecom denial — targeted denial of cellular and 5G links, from narrowband precision to wideband coverage. Facility and convoy protection — fixed-site, mobile and dismounted deployment.

Integration

Defender connects via REST API or the NATO SAPIENT protocol, acting as the defeat/engage layer alongside third-party radar, EO/IR and RF detection in a detect-track-classify-engage chain.
