150W GaN Anti-Drone Jammer Module for 720-1020 MHz

The 150W GaN anti-drone jammer module is a high-power analog interference source designed for counter-UAS operations in the 720–1020 MHz band. It integrates a broadband sweep generator, GaN driver stage, and final amplifier in a single metal-backed assembly. With a 24–29 VDC supply, the module delivers 150 W of continuous RF output while drawing up to 15 A. The design includes an absorptive VSWR protection device, overvoltage and overtemperature LEDs, and a TTL-compatible on/off control line. The SMA female output and compact 168.5 × 84.5 × 23 mm footprint make it suitable for vehicle, fixed-site, and portable jammer arrays.

GaN Technology for High Power Density

Unlike traditional LDMOS or bipolar modules, this 150W GaN anti-drone jammer module uses a gallium nitride final stage. GaN offers higher breakdown voltage, better thermal conductivity, and improved efficiency at elevated frequencies. With typical efficiency of at least 40%, the module converts less input power into waste heat. However, at 150 W output, roughly 225 W of heat must still be managed, so proper heatsinking is essential. The output VSWR of ≤2.0 means the amplifier remains stable even when the antenna is slightly detuned in field conditions.

Built-In Sweep Source and VSWR Protection

The internal analog sweep source covers 720–1020 MHz without requiring an external DDS or signal generator. Users can adjust the scan speed through control logic to generate a continuous noise-like waveform across the full band. A built-in absorptive VSWR protection device adds an extra layer of safety. If the antenna is accidentally disconnected or damaged, the protection network absorbs reflected power before it can damage the GaN transistor. This feature is especially useful for rapid deployment scenarios where antenna setup may be imperfect.

Electrical Interface and Control Logic

Supply voltage is 24–29 VDC with a maximum current draw of 15.0 A. The on/off control follows a simple logic: apply +5 V or leave the pin floating to enable RF output; ground the pin to turn the module off. The RF output connector is SMA female. Three LEDs indicate power, overvoltage, and overtemperature status. If the input voltage exceeds 29 V or the heatsink temperature rises too high, the corresponding LED lights up and the module may shut down to protect internal components.

Power Supply and Thermal Management

Because the 150W GaN anti-drone jammer module draws up to 15 A, the DC source must be capable of at least 18 A continuous to avoid voltage sag during modulation peaks. Use heavy-gauge wiring and place a low-ESR capacitor near the input terminals. Ripple should stay below 100 mV. For thermal management, mount the module on a large aluminum heatsink with thermal interface material. At 40% efficiency, about 225 W of heat is generated at full output, so forced-air cooling is recommended for continuous operation. The operating temperature range is -20°C to +65°C, but sustained high ambient temperatures require derating or additional airflow.

Applications and Deployment

This 150W GaN anti-drone jammer module is ideal for counter-UAS systems targeting lower-frequency drone control and video links. It can be paired with directional or omnidirectional antennas to create a denial zone in the 720–1020 MHz range. The analog architecture offers low latency and broad instantaneous bandwidth, which is useful against frequency-hopping threats. The module’s compact size and light weight (0.55 kg) allow integration into man-portable jammers, vehicle-mounted arrays, or fixed-site perimeter protection systems. Multiple modules can be combined to cover different frequency bands simultaneously.

Integration Summary

For integrators needing a robust high-power jammer block, the 150W GaN anti-drone jammer module reduces development time by combining the sweep source, GaN amplifier, VSWR protection, and control logic in one unit. A single 24 V supply, a TTL control line, and an SMA antenna are all that is required to bring up a basic jamming function. The module operates from -20°C to +65°C and includes overvoltage and overtemperature shutdown. Compared to multiple discrete components, this integrated design saves space, simplifies wiring, and improves reliability. The built-in VSWR protection further reduces the risk of field failures, making it a practical choice for demanding counter-UAS missions.
