80W GaN Drone Jammer Module | 4800–5000MHz Sweep Block

High-Power Jamming for the 5GHz Band

The 4800–5000MHz range is no longer a niche—it hosts an increasing number of UAV command links, video downlinks, and even some lightweight radar altimeters. This 80W GaN drone jammer module steps into that space with authority. Delivering a solid 80W of swept RF power, it addresses the growing need for effective countermeasures against drones that operate in this upper mid-band, where traditional lower-power modules often fall short.

This is not a scaled-up version of a lower-power design. The thermal and RF handling requirements at 80W demand a different approach—larger die, lower thermal resistance, and a more robust output stage. The module’s GaN-on-SiC HEMT technology provides the necessary power density while maintaining efficiency above 40%, ensuring that the extra watts translate into effective jamming range rather than excess heat.

Built-In Absorptive VSWR Protection – A Game Changer

One feature sets this module apart from typical jammers: an integrated absorptive VSWR protection device. When the antenna becomes mismatched—due to detuning, cable damage, or near-field obstructions—reflected power can overheat and destroy the output transistor. Most modules rely on simple reflection-based detection that just shuts down the unit. This one does more.

The internal protection circuitry absorbs reflected energy, keeping the amplifier safe while maintaining a controlled load impedance. This reduces stress on the GaN die and allows the module to continue operating (at reduced efficiency) until the mismatch is corrected. For field operators who cannot afford sudden system failures, this built-in safety net is a significant operational advantage.

Analog Sweep – Wide Coverage, No External Control

The onboard high-speed analog sweep source scans the entire 4800–5000MHz span automatically. There is no need for external modulation generators, digital pattern files, or synchronisation cables—just apply DC power and the module starts sweeping. The sweep rate is factory-tuned to outpace most drone frequency-hopping schemes, increasing the probability of link disruption even against spread-spectrum signals.

For applications that require custom sweep patterns, the drone jammer module accepts an external modulation input, giving you the flexibility to tailor the interference profile to specific threats. However, for 90% of deployments, the internal sweep performs admirably out of the box.

Thermal Management and Mechanical Integration

With 80W output and a maximum current draw of 10.0A at 24–29V DC, thermal design is critical. The enlarged housing—168.5mm long, 84.5mm wide, and 23mm high—provides a substantial surface area for conduction cooling. The aluminium baseplate acts as the primary heat path; we recommend bolting it directly to a metal chassis or an active heatsink for continuous operation.

The module weighs 0.55kg, which is remarkably light for an 80W amplifier. This weight reduction comes from the GaN technology and a carefully machined alloy enclosure that also serves as an EMI shield. Four mounting holes follow a standard pitch pattern, making retrofit into existing jammer frames straightforward.

Simple Enable Logic and Connector Compatibility

As with its lower-power siblings, the control interface is dead simple: +5V or floating turns the output on; grounding it turns it off. The SMA female output connector matches most standard antennas and test cables. For high-power handling, ensure your antenna and cabling are rated for at least 80W CW—a 50Ω termination with appropriate power capacity.

Real-World Deployment Scenarios

This 80W GaN drone jammer module shines in fixed installations where persistent airspace denial is required—military bases, government buildings, critical infrastructure perimeters. It also fits into vehicle-mounted systems for convoy protection and mobile C-UAS platforms. The 80W power level, combined with a directional antenna, can achieve effective disruption ranges well beyond what 20W or 30W modules can offer, especially in the 5GHz band where free-space path loss is steeper.

Durability and Environmental Tolerance

Rated for -20°C to +65°C ambient, this 80W GaN drone jammer module handles outdoor enclosures, rooftop deployments, and vehicle interiors without derating. The absorptive protection adds an extra layer of resilience against accidental open- or short-circuit conditions at the output port, reducing field failure rates.
