50W GaN Jamming Module – 600-700MHz Broadband Jammer

Overview

The 50W GaN Jamming Module is a purpose-built RF interference source covering 600-700MHz. It delivers 50W saturated output power within a compact 117×58×18mm enclosure, making it an ideal fit for drone countermeasure payloads, man-portable jammers, and fixed-site denial systems. Unlike conventional LDMOS designs, this module leverages gallium nitride on silicon carbide to achieve high efficiency and thermal stability.

Why GaN on SiC?

GaN-on-SiC technology provides superior power density and heat dissipation. The AB-class amplifier design ensures linearity while retaining efficiency. Mounted on a copper base, the module draws heat away from the active die, enabling continuous operation even at high ambient temperatures. This also reduces the need for bulky heatsinks, which is critical for weight-sensitive applications. The result is a rugged, long-life RF block that stands up to repeated use in the field.

Performance Highlights

This 50W GaN Jamming Module delivers 47±1 dBm output at 24-28V supply, drawing only 3.2-4.5A. The instantaneous bandwidth covers the entire 600-700MHz range without retuning, so you don’t need external filters or tuners. Input and output ports are 50 ohm impedance, compatible with standard SMA cables and antennas. The built-in high-speed noise modulation source offers an analog scan rate of 270kHz, which can be adjusted from 100 to 500kHz per request. For advanced users, external VCO, DDS, or SDR modulation can be integrated through a simple bypass option.

Compact and Tough

Weighing just 300g, the module fits into tight enclosures such as gimbaled turrets or backpack-style jammers. The operating temperature range -20°C to +65°C ensures reliable performance in outdoor or vehicle-mounted environments. SMA female connectors provide secure RF interfaces, and three LED indicators give real-time status for power-on, overvoltage, and overtemperature conditions. These features minimize troubleshooting time during field deployment and help prevent accidental damage.

Flexible Customization

Every deployment has unique requirements. This 50W GaN Jamming Module supports customization of scan speed, modulation type, mechanical dimensions, and even connector options. Whether you need a faster sweep for certain protocols or a specific form factor for integration, the design can be adapted. This reduces system-level modifications and speeds up project timelines. For example, if your system uses a different waveform generator, the internal source can be bypassed to accept external modulation without sacrificing output power.

Reliability and Protection

Overvoltage and thermal shutdown circuits protect the amplifier from supply surges or cooling failures. The rugged construction meets vibration and shock requirements typical for mobile platforms. With proper thermal management, the module maintains stable output across the whole frequency band, ensuring effective jamming without performance drift. This level of protection is especially valuable in unmanned systems where maintenance access is limited.

Typical Applications

Common uses include counter-UAS systems, spectrum denial, communication testing, and electronic warfare training. The 600-700MHz band covers many public safety and military communication channels, making this module versatile. For counter-UAS, the 50W GaN Jamming Module directly addresses drone command links and telemetry frequencies. Its low profile and low weight allow integration into gimbaled turrets or backpack systems without compromising platform agility.

Conclusion

In summary, the 50W GaN Jamming Module combines high power, wide instantaneous bandwidth, and robust construction in a small package. Backed by GaN-on-SiC and copper cooling, it offers a reliable solution for demanding RF jamming tasks. Customization options further enhance its adaptability, making it a future-proof choice for defense and security applications.
