80W GaN Drone Jamming Module | 700-840MHz Sweep Source

Protecting airspace against unauthorized drones demands robust RF countermeasures. The 80W GaN drone jamming module delivers high-power disruption in the critical 700-840 MHz band. Designed for integrators building fixed, vehicle-mounted, or portable anti-drone systems, this module packs a GaN power amplifier, a built-in high-speed analog sweep source, and comprehensive protection circuits into a compact 168.5 x 84.5 x 23 mm form factor. Weighing only 0.55 kg, it replaces bulky discrete-component setups with a single ready-to-deploy solution. The 80W GaN drone jamming module operates from a standard 24-29 V DC supply, drawing under 10 A at full output, and delivers true 80 W RF power to the antenna port.

GaN Technology Edge

Gallium Nitride technology allows this 80W GaN drone jamming module to achieve an efficiency of ≥40%, significantly reducing heat dissipation compared to older LDMOS designs. The high power density of GaN enables the module to output a saturated 80 W while keeping the footprint minimal. Input voltage range is 24-29 V DC, with a maximum current draw of 10.0 A. Onboard regulation and filtering ensure stable operation even in electrically noisy vehicle environments. Because less energy is wasted as heat, the aluminum baseplate and internal thermal management keep the unit within safe operating limits from -20 °C to +65 °C without forced-air cooling in many installations. This makes the 80W GaN drone jamming module ideal for sustained jamming missions where size, weight, and power constraints are critical.

Built-in High-Speed Analog Sweep

One standout feature is the fully integrated sweep source. Unlike conventional designs that require an external DDS or VCO module, the 80W GaN drone jamming module generates its own fast analog chirp that sweeps across 700–840 MHz in under 2 milliseconds. The sweep speed is preset at the factory and can be customized for specific threat profiles. This analog modulation creates a dense jamming signal that disrupts drone control and video links without the gaps that slow digital stepping can leave. Users simply apply DC power and a TTL enable signal—no extra RF cabling or reference oscillators needed. The immediate benefit is a simpler bill of materials and faster system integration.

Protection and Reliability

Robustness is critical in fielded counter-UAS hardware. The module incorporates an absorptive VSWR protection device directly at the output. If an antenna becomes disconnected or damaged, reflected power is safely dissipated, preventing damage to the GaN output stage. An onboard red LED illuminates to indicate a high-VSWR condition, while a green LED confirms normal operation. The output VSWR under matched conditions is ≤2.0 across the band. The output connector is an SMA female, compatible with common wideband antennas. TTL on/off control is straightforward: apply +5 V or leave the pin floating to enable the 80W GaN drone jamming module, and connect to ground to disable it.

Integration and Deployment

The compact dimensions and light weight make this module easy to embed in a variety of platforms. Its 168.5 mm length, 84.5 mm width, and 23 mm height allow it to fit inside drone gun enclosures, fixed-site jamming boxes, or UAV payload bays. The base material is a nickel-plated aluminum alloy cavity with a high-thermal-conductivity PCB, ensuring excellent heat spreading and corrosion resistance. Integrators can mount the module using the four corner holes and connect the DC input, TTL control, and SMA antenna. Because the 80W GaN drone jamming module combines the amplifier, sweep source, and protection in one block, system development cycles shrink from months to weeks.

Applications

Typical use cases include fixed-site perimeter drone defense at airports, prisons, and critical infrastructure; vehicle-mounted convoy protection; and handheld jamming guns. The 80W output ensures effective range against consumer and commercial drones operating on 700-840 MHz bands. Paired with a detection system, the module can be triggered automatically to create a no-fly zone. The fast analog sweep guarantees that frequency-hopping drones cannot easily avoid the jamming signal. All these features are delivered without the complexity of external waveform generators, thanks to the fully self-contained design.
