Powerful 150W GaN Jamming Module for 840–1000 MHz

The 150W GaN jamming module delivers a full 150 watts of continuous RF output across 840–1000 MHz. Built on a gallium nitride (GaN) power stage, this module targets drone control and navigation links in the sub-1 GHz band. It combines a high-power amplifier with an internal high-speed analog sweep source, so you get immediate broadband jamming without external modulation hardware.

Key Hardware Features

This 150W GaN jamming module uses a single SMA female output connector and a compact aluminum housing that measures 168.5 × 84.5 × 23 mm. It weighs 0.55 kg, making it practical for vehicle-mounted, portable, or fixed mast installations. The module runs from a 24–29 V DC rail and draws a maximum of 15.0 A at full output. Efficiency is at least 40%, which means less wasted heat for the same RF power compared to older LDMOS designs in this frequency range. A 50-ohm load is required; output VSWR should stay below 2.0 for normal operation.

Why GaN Makes a Difference

Gallium nitride transistors provide higher power density, better thermal conductivity, and greater ruggedness than silicon LDMOS at these power levels. The 150W GaN jamming module exploits these advantages to produce 150 W from a compact footprint. GaN also tolerates short VSWR mismatches well, but the module goes further by including an internal absorptive VSWR protection device. This feature safely dissipates reflected power instead of letting it stress the output stage. For continuous-duty counter-drone work, GaN keeps the module reliable even during antenna changes or cable faults.

Built-in Sweep Source and VSWR Protection

The module contains a built-in high-speed sweeping source that generates an analog modulation pattern across the full 840–1000 MHz band. Because the source and the GaN amplifier share the same board, the 150W GaN jamming module begins transmitting broadband energy as soon as the control line enables the RF chain. You do not need a separate DDS or arbitrary waveform generator. The absorptive VSWR protection device sits after the output matching network. If the antenna is disconnected or poorly matched, the protection element absorbs reflected power and reduces the risk of permanent damage.

Power, Switching, and Indicators

Control logic is simple: apply +5 V or leave the control pin floating to turn the RF output on, and ground the pin to turn it off. This works with most drone detection triggers, PLCs, or manual toggle switches. The maximum current draw is 15.0 A, so select a DC supply with at least 20 A continuous rating for reliable operation. Three LED indicators show power status, over-voltage, and over-temperature. If an over-temperature LED lights up, remove DC power and check the heatsink interface. The module is specified for -20°C to +65°C, but at the high end you must use forced air or a large heatsink.

Applications for the 150W GaN Jamming Module

This 150W GaN jamming module is designed for counter-UAS systems that need to disrupt drone control, telemetry, or video links in the 840–1000 MHz range. Many commercial and hobby drones use this band for long-range command and telemetry. The fast analog sweep defeats simple frequency hopping and fixed-channel receivers. You can trigger the module from a radar or RF detection unit for burst-mode operation, reducing average power consumption. Multiple modules can be combined with directional antennas to create higher effective radiated power over a specific sector.

Integration Notes

Always connect a matched 50-ohm antenna or dummy load before enabling the module. The SMA female port must never be left open at 150 W output. Use low-loss coaxial cable rated for at least 1 GHz and keep cable runs short. Mount the module on a flat metal surface or heatsink with thermal paste. The aluminum housing provides basic shielding, but for sensitive nearby receivers, place the module inside an additional screened enclosure. DC leads should be twisted and as short as possible.

Summary

The 150W GaN jamming module offers a high-power, compact, and efficient solution for 840–1000 MHz counter-drone operations. Its integrated sweep source, absorptive VSWR protection, and simple logic control make it easy to integrate into fixed, vehicle, or portable jamming platforms. With proper cooling and a matched load, it delivers stable, continuous RF output for demanding anti-drone missions.
