150W Jamming Module 5600-5900MHz: Serious RF Power for Modern Drone Threats

When you need to shut down unauthorised UAVs operating in the upper C‑band, a 150W jamming module delivers the kind of raw output that makes a real difference. This particular unit covers 5600–5900MHz – a frequency range increasingly used by advanced drones for video downlink and control. With 150W of swept RF energy, it can overwhelm receivers at considerable distances, even in cluttered environments.

What sets this module apart is not just the power, but the engineering behind it. Built around gallium nitride (GaN) technology, it achieves ≥40% efficiency while drawing 15A at 28V. The integrated sweep source means you don’t need external signal generators – just apply DC power and the module starts jamming immediately.

Why GaN Makes This 150W Jamming Module Stand Out

Gallium nitride is the enabler for high‑power, compact jammers. Compared to silicon or LDMOS, GaN handles higher junction temperatures and delivers better gain flatness across wide bandwidths. For a 150W jamming module, this translates into stable output even when the antenna load varies – a common headache in field deployments.

The efficiency figure of 40% is particularly important here. At 150W output, the module dissipates roughly 225W of heat (assuming 40% efficiency). That’s significant, but the GaN die can tolerate higher temperatures, allowing you to use a smaller heatsink than you’d need with older technologies. This keeps the overall package manageable at 168.5×84.5×23mm and 0.55kg.

Built‑in Absorptive VSWR Protection – A Game Changer

One of the most valuable features of this 150W jamming module is the integrated absorptive VSWR protection. Unlike simple reflective limiters that bounce mismatched power back into the amplifier, this device absorbs reflected energy, preventing overheating and potential transistor breakdown. It’s a safeguard that extends the module’s life, especially when you’re testing different antennas or operating near the edge of the VSWR ≤2.0 limit.

This protection works automatically – you don’t need to monitor it manually. The module also includes status LEDs for quick visual checks, though the absorptive circuit handles most fault conditions silently.

Integrated Sweep Source Saves Space and Integration Effort

Many jamming systems require an external waveform generator to produce the sweeping frequency that disrupts drone links. This 150W jamming module eliminates that extra box. The internal analogue sweep source covers the entire 5600–5900MHz band at a factory‑set speed, creating a continuous interference blanket. You simply control the on/off state via a +5V or floating input – ground to disable.

This design reduces BOM cost, cuts wiring complexity, and speeds up prototyping. Whether you’re building a handheld jammer, a fixed tower system, or a mobile unit, this drop‑in approach simplifies the RF chain.

Real‑World Deployment Considerations

Powering the module is straightforward: DC24–29V, with a maximum current draw of 15A at full tilt. A standard 24V or 28V power supply works fine, but ensure it can deliver at least 18A to provide headroom. The SMA female output connects to your antenna – choose a 50Ω type rated for 200W or more to handle the peak envelope power.

The operating temperature range of -20°C to +65°C covers most outdoor scenarios. However, continuous operation at 150W will generate substantial heat; a forced‑air heatsink or liquid cooling plate is recommended for permanent installations. The aluminium base provides good thermal spreading, but you’ll need to mate it with an appropriate cooling solution.

Typical Applications for This Jamming Module

• Counter‑UAS defence – Disrupt drone video feeds and command links at medium to long ranges.

• Test & measurement – Use as a high‑power interference source for receiver desensitisation tests.

• Electronic warfare training – Simulate realistic jamming scenarios for military or security drills.

• Perimeter security – Deploy multiple modules to cover large areas with overlapping coverage.

The 150W output level is enough to compete with most commercial drone transmitters, which typically range from 100mW to a few watts. With a directional antenna (e.g., panel or log‑periodic), effective range can exceed several kilometres under clear line‑of‑sight conditions.

Mechanical and Electrical Summary

The module’s compact footprint (168.5mm long) allows it to fit into standard 19″ rack enclosures or ruggedised portable cases. Weight is just 0.55kg, making it manageable for handheld designs. All critical specifications are listed in the table below.

For system integrators needing serious jamming capability, this 150W jamming module delivers the power, protection, and simplicity that field‑ready equipment demands. With built‑in sweep generation and absorptive VSWR safeguarding, it reduces design risk and accelerates deployment. Pair it with a suitable antenna and cooling, and you have a robust C‑UAS frontend that performs when it counts.
