20W Drone Jammer Module 3400-3600MHz

Sometimes you don’t need kilowatts. What you need is a tightly focused, lightweight module that punches exactly where mid-band drone links operate — and does it without draining a truck battery. This 20-watt LDMOS drone jammer module, covering 3400 to 3600 MHz, fills that gap. It ships with a built-in high-speed sweep generator, a simple TTL on/off interface, and a footprint that barely takes up more space than a business card. No external signal source, no complicated serial commands. Just feed it 24–29 V DC, toggle the control line, and the module starts painting dense sweeps across the whole 200 MHz band.

Where the 3.4–3.6 GHz Band Matters

A growing number of commercial and industrial drones rely on 3.5 GHz for control, telemetry, or video — especially in regions where this spectrum has been allocated for broadband wireless access. It sits above the crowded 2.4 GHz ISM band, so interference tends to be lower, but that also makes it a favorite for drones engineered for long-range operations. This module was purpose-built to deny that exact window without wasting energy on irrelevant frequencies. The integrated sweep source cycles fast enough to catch even frequency-hopping schemes, yet the whole thing weighs just 210 grams.

Simplicity That Speeds Up Integration

One of the first things you’ll notice is the dead-simple control logic. The module turns on when you apply +5 V to the control pin or leave it floating; ground that same pin and it shuts down. No SPI bus, no UART commands, no scripting. For integrators building drone detection-and-defeat boxes, this means you can wire the module straight to a relay, a manual toggle, or a detection system’s GPIO line and have it respond instantly.

The SMA female output makes antenna mating trivial. Whether you’re screwing on an omnidirectional sleeve dipole for wide coverage or a panel antenna for a directional beam, there’s no need for exotic adapters. At 20 watts, the module is especially well-matched to portable and man-worn jammers, where battery life and heat dissipation are the limiting factors. The ≥40% efficiency rating means less DC power wasted as heat and more converted into useful RF energy.

Thermal Behavior and Duty Cycle

With a maximum current draw of 2.5 amps at 28 V, the module generates roughly 35–40 watts of heat under worst-case conditions. The aluminum baseplate is designed to bolt directly to a heatsink, a metal enclosure wall, or even a small fan-cooled chassis. For short-duration jamming bursts — the most common real-world scenario — passive cooling is usually sufficient. If your operation requires continuous transmit, simply mount the module to a finned extrusion and provide modest airflow. The operating range of -20 to +65 °C gives you plenty of environmental leeway.

When to Choose This Drone Jammer Module Over Broader-Band Units

Broadband jammers have their place, but they also spread energy thin. This module concentrates all 20 watts into a specific 200 MHz slice that overlaps critical drone frequencies. The result is a higher power density right where you need it, without raising the total system weight or power budget. It’s an ideal building block for layered counter-UAS architectures — for example, pairing it with a 5.8 GHz unit to cover dual-band drones in a single enclosure.
