100W 758-788MHz GaN Drone Jammer Module

Integrated Sweep Generator & Power Amplifier

The 758-788MHz 100W GaN Module is a complete jamming solution engineered for Counter-Unmanned Aerial Systems (C-UAS). This all-in-one module integrates a high-power GaN amplifier with a built-in high-speed sweep generator, delivering 100W of instantaneous jamming power across the entire 758-788MHz band.

Designed for reliability in demanding environments, it utilizes GaN-on-SiC technology mounted on a copper base for superior thermal management. The result is a compact, lightweight, and highly efficient jamming module ready for integration.

Frequently Asked Questions

Q1: Why is the 758-788MHz band important for drone jamming?

This frequency range is commonly used for drone command and control uplinks. By jamming 758-788MHz, you disrupt the communication between the drone and its operator, forcing the drone into fail-safe mode (return-to-launch or landing) or causing it to lose control entirely. It’s a critical band for neutralizing UAV threats.

Q2: Does this module include everything needed to start jamming?

Yes. The drone jammer module contains both the high-speed sweep generator and the 100W power amplifier in one housing. You only need to provide 24-29V DC power and a TTL control signal. It generates the sweeping jamming signal internally and amplifies it to 100W, ready for connection to an antenna.

Q3: How does the built-in VSWR protection work?

The module features absorptive VSWR protection. Unlike reflective designs that bounce excess power back into the amplifier (which can cause damage or frequency instability), this circuit absorbs reflected power from antenna mismatches. This ensures the GaN transistor remains safe even if the antenna is damaged, disconnected, or poorly matched.
