30W GaN Jamming Module – 1550-1620MHz Blocker

Lightweight Muscle for Targeted Interference

When your mission calls for jamming GPS or telemetry links in the 1550–1620MHz band, this 30W GaN jamming module offers a sweet spot between output power and portability. Weighing just 0.21kg and measuring smaller than a smartphone, it slides into backpacks, handheld units, or small UAV payloads without straining your power budget. The gallium nitride design delivers 30W of clean analog sweep power while drawing only 3.2A at 28V – a combination that keeps batteries happy and field operators moving.

Efficient Operation in a Tiny Enclosure

Despite its size, the module maintains ≥40% efficiency across the full supply range (24–29V DC). That means less wasted heat and more usable energy for actual jamming. The output VSWR stays ≤2.0, and the SMA female connector provides a solid 50‑ohm interface for any standard antenna. You do not need bulky heatsinks – the aluminium baseplate (115.5×46.5×21mm) handles moderate duty cycles on its own, and an optional fan extends continuous operation. For mobile teams, this 30W GaN jamming module becomes a go‑to tool for quick deployment.

Simple Control, Built‑In Sweep Source

Like its bigger siblings, this unit includes an internal high‑speed analog sweep oscillator – no external signal generator required. The sweep covers the entire 1550–1620MHz range in milliseconds, effectively disrupting frequency‑hopping and fixed‑channel receivers commonly found in commercial drones. Enable the module by leaving the control pin open or applying +5V; ground it to shut down. This straightforward logic works with any MCU or manual toggle, so integration takes minutes, not hours.

Thermal and Mounting Considerations

Rated for -20°C to +65°C ambient, the 30W GaN jamming module performs reliably in outdoor environments. The nickel‑plated aluminium alloy base acts as both a heatsink and a sturdy mounting surface – use thermal paste and four screws to attach it to a chassis or cold plate. At full power, case temperature rises gradually; we recommend staying below 70°C for continuous use. Without active cooling, limit duty cycle to 50% at 25°C room temperature. For airborne applications, the low mass (0.21kg) reduces payload strain, making this 30W GaN jamming module a favourite among drone‑based counter‑UAS systems.

Where This 30W GaN Jamming Module Excels

• Handheld jammer guns for security teams

• Vehicle‑mounted denial systems

• Laboratory receiver susceptibility tests

• Rapidly deployable perimeter protection

Its moderate power level avoids over‑kill while still blanking most consumer‑grade drone links within effective range. The built‑in sweep eliminates complex programming, and the low current draw allows operation from standard Li‑Po batteries. Field tests show consistent output across temperature extremes, thanks to GaN’s inherent ruggedness.

Integration Tips for Quick Setup

Connect a 28V supply capable of 4A continuous (3.2A typical). Attach a 50‑ohm load – never power without an antenna or dummy load. Use a heat‑conductive pad between the baseplate and your heatsink. For duty‑cycle control, add a simple timer to the enable pin. If you need lower output, insert an external attenuator. The module has no built‑in VSWR protection, so ensure your antenna match is good – a directional coupler with a reflected‑power monitor is advised for critical missions. Despite this caution, the 30W GaN jamming module remains one of the most cost‑effective solutions for its frequency and power class.

Final Verdict

This small‑form‑factor jammer punches well above its weight. It combines the advantages of GaN – efficiency, thermal tolerance, and power density – with a self‑contained sweep source, making it a plug‑and‑play RF weapon for both novice integrators and seasoned engineers. Whether you are defending a convoy or testing new receivers, the 30W GaN jamming module delivers reliable, repeatable interference in a package that fits everywhere.
