30W GaN UAV Jamming Module 4800-5000MHz: Reliable C-UAS Frontend

When dealing with unauthorised drones in sensitive zones, you need a jammer that combines muscle with smart engineering. The 30W GaN UAV jamming module is exactly that—a self-contained RF frontend built for the 4800–5000MHz band, often used by commercial and hobbyist UAVs.

This isn’t just another amplifier board. It includes an internal high-speed frequency sweep generator, so you don’t have to feed it an external modulation signal. You apply DC power, and the module immediately starts sweeping the entire 200MHz bandwidth. This makes integration into portable jammers, fixed sites, or vehicle-mounted systems far simpler.

Why GaN Matters for UAV Jamming

Gallium nitride (GaN) technology is the backbone of modern high-power RF design. Compared to older LDMOS or silicon-based transistors, GaN runs cooler, survives higher voltage stress, and delivers better linearity under mismatch.

For a 30W GaN UAV jamming module, this translates directly into field reliability. The unit can operate with a supply voltage between 24V and 29V, drawing a maximum of just 3.2A at full tilt. That means you don’t need a massive power supply—a standard 24V battery pack or compact AC/DC unit will do.

The efficiency rating of ≥40% is particularly useful in portable scenarios. Lower heat generation means smaller heatsinks and lighter enclosures, which is critical when you’re carrying the system in a backpack or mounting it on a gimbal.

Built-In Sweep Source Saves Space

One of the most valuable features is the integrated analogue modulation source. Many jamming modules require an external signal generator or a dedicated FPGA board to produce the sweeping waveform. Here, the sweep is already inside the housing. This simplifies the end-product BOM and reduces overall system size.

The internal source sweeps the 4800–5000MHz range continuously. The speed is factory-set to cover the entire band rapidly enough to disrupt drone control and telemetry links. The result is a blanket of interference across common C-band UAV channels.

Designed for Real-World Deployment

The mechanical layout is practical. With dimensions of 115.5×46.5×21mm and weighing only 0.21kg, the module fits into tight spaces—perfect for handheld disruptors or under-slung payloads.

The output port is an SMA female connector, making it easy to attach a suitable antenna. The enable control is straightforward: apply +5V or leave the pin floating to turn the unit on; ground it to shut it down. This simple TTL-style interface plays nicely with microcontrollers, manual switches, or safety interlock circuits.

Thermal performance is rated from -20°C to +65°C, covering most operational theatres. The aluminium housing and base material provide reasonable heat spreading, but you should still use an appropriate heatsink for continuous duty at 30W.

Typical Application Scenarios

• Portable counter-UAS rifles – Light weight and high efficiency keep the device manageable.

• Fixed-site perimeter security – Install several modules to cover different sectors.

• Vehicle-mounted response units – Withstand vibration and temperature swings.

• Test equipment – Use as a dedicated interference source for receiver testing.

The module outputs 30W of swept RF energy, which is sufficient to overwhelm most consumer drone receivers within line-of-sight ranges. Actual effective range depends on the antenna gain and environmental conditions, but the power level gives you a solid starting point.

What About Protection and Monitoring?

The unit includes onboard protection features. While specific LEDs are indicated in the table below, the general design accounts for over-voltage and high VSWR conditions. Operating into a severe mismatch (above 2.0:1) is not recommended, but the GaN transistor is more forgiving than older technologies.

For integrators looking for a drop-in RF solution, the 30W GaN UAV jamming module offers a sensible balance of power, efficiency, and built-in intelligence. It eliminates the external sweep generator, reduces cabling, and cuts development time. Whether you’re building a dedicated jammer or upgrading an existing system, this module handles the heavy lifting in a compact footprint.
