The 60W jamming module fills a critical niche for portable counter-UAS systems—powerful enough to overwhelm UHF drone control links yet compact enough for handheld jammers and small UAV payloads. Operating from 840 to 1000 MHz, this GaN-based analog jammer targets the popular 900 MHz ISM band used by many commercial drones. Unlike solutions that depend on external signal generators, it embeds a high-speed analog sweep source right on the board. Weighing only 0.22 kg and measuring 138×50.5×17 mm, the module enables integrators to build lighter counter-drone gear without sacrificing RF punch. As a result, system designers can significantly reduce the size and weight of their counter-drone payloads.

GaN Efficiency in the 60W Jamming Module

The compactness of the 60W jamming module is a direct result of Gallium Nitride technology. Traditional LDMOS amplifiers at this power level would require a much larger heatsink and still risk thermal throttling. The GaN-on-SiC design delivers over 40% power-added efficiency while maintaining a stable 60 W output across the entire 840–1000 MHz span. This efficiency minimizes waste heat, enabling a slim 138×50.5×17 mm chassis. An aluminum alloy baseplate with a gold-plated copper heat spreader rapidly pulls heat away, allowing continuous-duty operation from -20 to +65 °C. GaN also provides superior linearity and ruggedness under high VSWR conditions, further extending the module’s operational life. For integrators, the 0.22 kg weight makes the module ideal for drone-mounted jammers or rapid-deployment kits. (Learn more about GaN RF power at Wolfspeed.)

12V Power and TTL Control

The 60W jamming module runs on a convenient 12–14 V DC supply, perfectly matching automotive batteries, LiFePO4 packs, and common DC bus voltages. It draws up to 12 A when delivering full 60 W, so a 15 A rated supply is advised. The wide input voltage range absorbs dips common in battery-powered deployments, ensuring the jammer stays online without interruption. To activate the jammer, apply +5 V or simply leave the TTL control pin floating; pulling it to ground instantly stops transmission. This straightforward logic allows direct interfacing with drone detectors, radar triggers, or manual switches, without complex microcontrollers. The SMA female connector accepts a wide variety of UHF antennas; pairing the module with a high-gain 900 MHz yagi or panel antenna dramatically extends the jamming footprint. 

Agile Sweep Performance of the 60W Jamming Module

At the core of the 60W jamming module is an on-board high-speed analog sweep source. It rapidly scans the full 160 MHz bandwidth, from 840 to 1000 MHz, with a typical step rate of 500 kHz. This aggressive sweeping ensures that frequency-hopping drones cannot maintain a stable control or video link. The analog approach generates a noise-like jamming signal that simultaneously disrupts multiple narrowband channels, eliminating the need for complex digital modulation. Because the modulation engine is integrated, no external waveform generator or PC is needed—simply supply power and connect an antenna. Field tests show the jammer reliably severs command links of popular consumer UAVs at practical standoff ranges for perimeter security. The module’s -20 to +65 °C operating temperature guarantees performance in harsh outdoor environments.

Protection Features

To survive real-world antenna mismatch, the 60W jamming module integrates an absorptive VSWR protection circuit. Instead of reflecting dangerous reverse power into the GaN transistor, the circuit safely dissipates it, preventing catastrophic failure. Two LEDs give at-a-glance status: green for normal operation and red when VSWR exceeds safe thresholds. Even with a severely mismatched antenna, the module remains operational, minimizing downtime during critical missions. This built-in safeguard, together with the efficient GaN thermal design, makes the module exceptionally robust for 24/7 fixed installations, vehicle-mounted masts, or portable cases.
