30W L-Band Signal Disruption Module for 1550-1620MHz Applications

This 30W Analog Jammer Module provides focused, high-performance interference within the critical 1550-1620MHz L-band spectrum. This frequency range is essential for disrupting global navigation satellite system (GNSS) signals such as GPS L1 and GLONASS, as well as specialized data links used by advanced unmanned platforms. Engineered into an exceptionally compact and self-contained unit, it integrates a high-speed sweep source to deliver reliable wideband jamming, making it a vital component for precision electronic countermeasure (ECM) and force protection systems.

Ideal for low-SWaP-C (Size, Weight, Power, and Cost) deployments, this module balances substantial output power with remarkable efficiency. Its design prioritizes seamless integration into man-portable equipment, mobile platforms, and fixed-site defenses where neutralizing positioning, navigation, and timing (PNT) data is operationally decisive.

Product Highlights and Innovation

• Precision L-Band Targeting: Engineered specifically for the 1550-1620MHz band, a key spectrum for satellite-based navigation and high-reliability communication links, enabling precise denial of enemy PNT capabilities.

• High Power Density: Generates a potent 30W of RF output from a minimal footprint (115.5×46.5x21mm), offering one of the best power-to-size ratios in its class for tactical mobility.

• Fully Integrated Solution: Houses a built-in, high-speed analog sweep generator, providing a complete “jammer-on-a-board” that eliminates external signal source dependencies and simplifies system architecture.

• Superior Power Efficiency: Operates at ≥40% efficiency from a standard 24-29VDC supply, maximizing operational duration for battery-powered applications and minimizing thermal output.

• Simplified Control Scheme: Utilizes a straightforward TTL-compatible enable/disable pin (+5V/Open=ON, GND=OFF) for easy remote activation via system controllers or manual switches.

• Robust Mechanical Design: The shielded, lightweight aluminum enclosure ensures durability and electromagnetic compatibility (EMC) in demanding field environments.

Intended Operational Use Cases

This module is designed for scenarios requiring denial of L-band signals to degrade an adversary’s situational awareness and operational effectiveness.

• GNSS Denial for C-UAS: A core component in counter-unmanned aerial system (C-UAS) solutions to jam the navigation receivers of drones, causing loss of positioning and enabling capture or safe deflection.

• Tactical Force Protection: Protects convoys, forward operating bases, and personnel by creating a localized bubble of GNSS interference, countering threats reliant on precise coordinates (e.g., some guided munitions).

• Electronic Warfare (EW) Training: Serves as a realistic threat emitter in training environments to test and harden friendly forces’ equipment and tactics against GNSS-jamming scenarios.

• Critical Infrastructure Security: Deployed to safeguard sensitive locations from unauthorized aerial or ground-based surveillance systems that depend on L-band data links for operation.
