150W Drone Jammer Module: 6900-7200MHz GaN Board

The 150W drone jammer module is a high-power GaN countermeasure board designed for the 6900–7200 MHz band. It combines a built-in high-speed analog sweep source with a gallium nitride final amplifier to produce 150W of RF output from a compact aluminum chassis. Because the source and amplifier are integrated, system builders do not need a separate signal generator or complex RF routing. This module suits fixed, vehicle-mounted, and portable anti-drone platforms. With an output VSWR of ≤2.0 and built-in absorptive VSWR protection, it is designed to survive antenna mismatch conditions that can damage unprotected amplifiers.

High-Power GaN Output Stage

The 150W drone jammer module uses a GaN device in the final stage. GaN offers high power density and stable thermal performance, which helps maintain output across 6900–7200 MHz. The amplifier delivers 150W typical output at 24–29V DC, with efficiency of ≥40%. That power level supports directional jamming at extended ranges when paired with a high-gain antenna. The RF output connector is SMA female, and system impedance is 50Ω. Use a short, low-loss cable between the module and antenna to reduce losses at these frequencies.

Frequency Coverage and Built-In Sweep Source

This 150W drone jammer module covers 6900–7200 MHz, a band used by some UAV communication and video links. The internal high-speed analog sweep source continuously sweeps the full operating band, producing dense interference without external modulation. The analog sweep creates a smooth noise-like envelope that can disrupt fixed-frequency and frequency-hopping signals. For integrators, that means fewer RF components and simpler control. Once DC power and a control signal are applied, the module is ready to transmit.

Built-In VSWR Protection

High-power amplifiers are often damaged by antenna mismatch. The 150W drone jammer module includes an absorptive VSWR protection device that absorbs reflected energy instead of sending it back into the GaN stage. This adds a safety margin in field installations where antenna placement or cable damage can cause high VSWR. It is not a substitute for a properly matched antenna, but the protection reduces the risk of immediate failure from open or shorted loads. Always check the antenna and cable before enabling RF.

Power and Switching

The module runs from DC24V–29V and draws up to 15.0A at full output. A regulated supply rated for at least 18A is recommended, with short and heavy-gauge power wires to limit voltage drop. On/off control is simple: +5V or a floating control pin enables RF output, while grounding the pin disables it. This logic works with microcontrollers, relays, and toggle switches. No serial commands are needed. The 150W drone jammer module does not require a separate bias sequence; connect the antenna first, then apply power and control in any order.

Thermal and Mechanical Design

At 150W output and ≥40% efficiency, the module dissipates roughly 225W of heat at maximum power. The base is aluminum and should be mounted to a large heatsink or metal enclosure with thermal compound. Dimensions are 168.5×84.5×23mm, and weight is 0.55kg, so the module fits into many rack-mount and portable enclosures. For bench testing, use a heatsink with forced air. In field installations, provide adequate airflow and monitor case temperature. Operating range is -20°C to +65°C; sustained high-temperature use requires derating or improved cooling.

Typical Applications

The 150W drone jammer module is intended for authorized counter-UAV and security applications, including perimeter defense, convoy protection, critical infrastructure security, and portable jamming systems. It works with directional antennas for focused energy or omnidirectional antennas for sector coverage. Directional antennas are generally more effective at long range because they concentrate the 150W output into a narrower beam. Multiple modules can cover other frequency bands, but RF isolation and thermal spacing should be planned carefully.

Operating Notes

Always connect a 50Ω antenna or load before enabling the module. RF exposure near the antenna is hazardous, so follow applicable safety regulations. Operation may be restricted by national spectrum laws. This 150W drone jammer module is for professional and authorized use only. After installation, check supply current, output VSWR, and output power to verify normal operation.
