Powerful 100W Jamming Module – 500-600MHz GaN Counter-Drone

When you need reliable RF suppression across the 500–600 MHz band, the 100W jamming module delivers a powerful, all-in-one countermeasure. Built around advanced gallium nitride (GaN) transistors, this module combines a high-speed analog sweep source, solid-state amplification, and VSWR protection into a compact 168.5 × 84.5 × 23 mm package. Whether you’re developing a fixed-site drone defense system or a portable jamming backpack, this module simplifies your RF chain.

GaN Technology Powers This 100W Jamming Module

Why GaN? Traditional LDMOS-based designs often struggle with efficiency and thermal management at these power levels. Our 100W jamming module uses GaN HEMT technology to achieve ≥40% efficiency, meaning less waste heat and smaller heatsinks. That 100-watt output stays clean across the whole 500–600 MHz range, so you can jam multiple drone protocols without annoying dropouts. (Read more about GaN benefits on Everything RF.) The module runs off a single 24–29 V DC supply and draws no more than 12 A at peak—manageable even for battery-powered deployments.

Integrated Analog Sweep Source

One clever aspect of this design is the built-in analog sweep generator. Instead of piping in an external DDS or VCO, the 100W jamming module includes an internal high-speed sweep source that continuously shifts the carrier across the band. The sweep speed is configurable (typically >200 MHz/ms), letting you optimize for different drone frequency-hopping patterns. And because it’s an analog sweep, you avoid the spurs that sometimes plague digital synthesis. For developers, this means faster integration and fewer components to source. Simply apply +5 V or leave the control pin floating to activate, and ground it to turn off—dead simple.

Built-In Protection and Ruggedness

Nothing kills a power amplifier faster than a badly matched antenna. This module features absorptive VSWR protection that monitors reflected energy and safely dissipates it before the GaN transistor sees a dangerous level. A front-panel LED lights up when the VSWR crosses the threshold, giving you a clear visual warning. The output connector is SMA female with 50-ohm impedance, and the typical VSWR under normal operation stays ≤2.0:1. The aluminum alloy baseplate wicks heat away efficiently, and the whole unit weighs just 0.55 kg—sturdy yet light enough for airborne payloads if needed.

Compact Integration for Real-World Deployments

With dimensions of 168.5 × 84.5 × 23 mm, the 100W jamming module fits into tight enclosures. Whether you mount the 100W jamming module in a vehicle or a fixed installation, you’ll appreciate the straightforward mounting holes and single-connector RF interface. You can stack multiple units for multi-band systems or pair it with our high-power PA modules for wider coverage. The wide operating temperature range (-20 to +65 °C) means it handles desert heat and winter cold equally well. Just ensure you provide clean DC power and sufficient airflow; the module’s baseplate temperature should stay below 85 °C for maximum reliability.

Where This 100W Jamming Module Excels

This module is purpose-built for counter-unmanned aerial systems (C-UAS). The 500–600 MHz segment covers many commercial drone command links, telemetry channels, and even some video feeds. By saturating this entire chunk of spectrum with a fast-sweeping carrier, you can effectively disable DJI, Autel, and homebrew UAVs that rely on sub‑1 GHz ISM bands. It’s also useful for testing RF immunity of military radios or creating secure perimeters. Remember to check local regulations (FCC jammer rules) before transmitting—unauthorized jamming is illegal in most jurisdictions.
