50W Drone Jammer Module – 840‑1000MHz GaN Amplifier

Reliable Countermeasures Start with the RF Core

When you are building a drone interception system, the power stage decides the effective range and the jamming quality. This 50W drone jammer module operates across 840‑1000MHz – a sweet spot for many civilian and military communication links used by small UAVs. Designed around a GaN-on-SiC die, it delivers stable 47±1 dBm (50W) output while staying cool enough for sustained field operations. No exotic cooling loops, no fragile tuning – just a robust, drop‑in amplifier that does its job.

Why GaN Makes the Difference

Older LDMOS designs struggle with efficiency and heat at this power level. Our module uses gallium nitride on silicon carbide, mounted directly on a copper heat‑spreader. This combination cuts thermal resistance and allows the device to handle mismatched loads without degrading. The AB‑class topology balances linearity and power consumption, so you get clean spectral performance even when the input signal is a fast‑hopping noise source. Field data show that the mean time between failures comfortably exceeds 5,000 hours under typical jamming duty cycles.

Built‑In Modulation – No External Generator Needed

Many competing modules require an external VCO or DDS board to feed the RF input. This unit includes a high‑speed noise modulation source as standard – it generates a digitally‑shaped interfering waveform that effectively breaks both analog and digital control links. The scan rate is preset at 270 kHz, but we can tailor it between 100 and 500 kHz per your request. If you prefer an external synthesizer, we also offer variants with SMA input for VCO, DDS, or SDR front‑ends. That flexibility means you can use the same amplifier chassis across multiple projects without redesigning the driver stage.

Electrical and Mechanical Fit

The drone jammer module runs from a nominal 28V supply (tolerates 24‑28V) and draws 3.2‑4.5A depending on the modulation content and output level. That translates to roughly 90‑126W of DC input – a power efficiency around 40‑55%, which is excellent for a broadband AB‑class GaN amplifier. The RF ports are female SMA (50Ω impedance), and the internal matching network ensures VSWR below 1.8:1 across the entire band. You will appreciate the small footprint: 117 mm long, 58 mm wide, and only 18 mm tall. At 300 grams, it fits neatly into handheld disruptors, backpack units, or fixed tower enclosures.

Protecting Your Investment

Field equipment takes abuse – voltage transients, accidental over‑drive, or summer tarmac heat. The board integrates three LED indicators: power‑on, over‑voltage, and over‑temperature. When the heatsink temperature exceeds 85°C, the protection circuit reduces bias to prevent permanent damage, and the red LED lights up. The operating range is -20°C to +65°C for continuous duty, with derating above 55°C if you run full‑power CW. For intermittent jamming (e.g., 50% duty cycle), you can safely push to 70°C ambient.

Customization That Makes Sense

Every deployment environment differs. We support custom scan speeds (100‑500 kHz), alternative input sources (external VCO/DDS/SDR), and even mechanical dimensions for tight enclosures. The copper base can be drilled or tapped to your pattern, and we can change the SMA orientation from horizontal to vertical. Minimum order quantities for customization are modest – we understand that counter‑UAS developers often work in small batches. Just provide your required frequency subset, output connector type, and thermal budget, and we will propose a variant within two working days.

Real‑World Performance Snapshot

In our lab tests, the module achieved 47.2 dBm at 920 MHz with a 28V supply, consuming 4.1A. Harmonic suppression was better than -20 dBc, and the spur level stayed below -65 dBc. When we swept temperature from -20°C to +65°C, output power drifted less than ±0.5 dB – that is the GaN advantage. The built‑in noise source has a crest factor of 6‑8 dB, which effectively confuses both GPS‑aided and command‑link receivers. For customers who need frequency hopping jamming, we recommend pairing this module with our SDR interface board that updates the modulation every 10 ms.

Installation Tips

Use a low‑loss RF cable (e.g., RG‑316 or semi‑rigid) between the signal source and the module input. Ensure the heatsink surface is flat and apply a thermal grease of at least 3 W/m·K before mounting to your chassis. The ground plane should be continuous – we provide four M3 mounting holes on the corners. Never apply input power exceeding +10 dBm, otherwise the internal attenuator may saturate. For remote monitoring, the LED status lines can be read via opto‑isolators (not included) – contact us for the pinout.

Final Word

This 50W drone jammer module is not a toy – it is a professional tool for security forces, test ranges, and critical infrastructure protection. We have shipped hundreds of units to clients across Europe, Asia, and the Americas, with a return rate below 0.3% over two years. The combination of wideband performance, integrated modulation, and rugged packaging makes it a reliable choice. If you are still comparing specifications, order a sample unit – we offer a 30‑day performance guarantee. Your jamming system deserves a power amplifier that does not let you down when it matters most.
