100W UAV Jamming Module: GaN 3.4-3.6 GHz Countermeasure

In modern counter-UAS operations, a compact yet powerful RF jammer is no longer optional—it is essential. The 100W UAV Jamming Module answers that call with a full 100 watts of output blanketing the 3400–3600 MHz band, the sweet spot where most commercial drones communicate. Built on gallium nitride technology and housing a high-speed analog sweep source, this module delivers a ready-to-integrate jamming core for portable drone guns, fixed-site domes, or vehicle-mounted protection systems. With protections already baked in and a footprint smaller than a tablet, it drastically cuts engineering time for defense integrators.

Power Density Redefined

Despite its formidable output, the 100W UAV jamming module measures only 168.5 × 84.5 × 23 mm and tips the scale at 0.55 kg. That kind of power density is made possible by a GaN-on-SiC RF chain and a carefully optimized thermal path that dumps heat straight into the aluminum alloy base plate. Gold-plated contacts maintain low insertion loss and resist corrosion even in humid field conditions. An SMA female connector keeps RF routing clean, and the 50-ohm impedance matches virtually every standard antenna on the market. For system builders, this means the module slips effortlessly into pelican cases, pan-tilt platforms, or custom enclosures without hogging space.

Why Gallium Nitride Changes the Game

Inside the module, a GaN power amplifier stage pushes overall efficiency past 40%, which directly cuts current draw to no more than 12 A from a 24–29 V DC bus. GaN transistors switch fast, tolerate high junction temperatures, and maintain linearity at full 100W CW operation across the entire 3400–3600 MHz range. Compared to older LDMOS or GaAs designs, the GaN-based 100W UAV jamming module generates less waste heat under sustained key-down conditions, reducing the size and cost of external cooling. Whether you are running short bursts or continuous jamming loops, the thermal headroom keeps performance consistent from -20°C to +65°C.

Built-In Analog Sweep Source

No external signal generator is required. The module embeds a fast analog sweep source whose step rate is configurable—typically between 100 kHz and 1 MHz per hop—to create a wideband noise-like jamming waveform. That waveform is particularly effective against frequency-hopping spread spectrum (FHSS) protocols used by popular drone brands. Because the modulation engine is pre-integrated and impedance-matched, you simply supply DC power and a TTL command to activate the 100W UAV jamming module, eliminating the tuning headaches that often accompany discrete amplifier-signal-generator chains.

Protection and One-Wire Control

Field reliability is built around an absorptive VSWR protection circuit that shields the GaN output stage from antenna mismatch, open, or short conditions. Dual LED indicators give instant status feedback: one green for normal operation, one red for VSWR fault or over-temperature events. Control logic is equally simple—apply +5 V or leave the control pin floating to turn the module on, and pull it to ground to turn it off. With its aluminum alloy chassis and wide temperature rating, this 100W UAV jamming module holds up under real operational stress while its integrated protection features prevent the most common failure modes.

When the mission demands a high-power, single-box jamming solution that drops into existing systems with minimal fuss, this module stands out. It combines GaN efficiency, wideband analog sweep, and rugged protection inside a lightweight footprint, giving field engineers a trusted building block for drone defense.
