Powerful 100W GaN Jamming Module 700-900MHz

The 100W GaN jamming module covering 700-900 MHz is not your average RF amplifier. It puts out a full 100 watts across the entire band without tuning, and it does it from a package that weighs just 800 grams. If you are building a drone jammer or a counter-UAS system, this module eliminates the need for bulky rack-mounted gear.

Why This 100W GaN Jamming Module Beats LDMOS

Gallium nitride on silicon carbide handles higher voltage and heat than LDMOS or GaAs. Here’s the thing: the AB-class design keeps efficiency high while preserving signal quality for noise modulation. And because it sits on a copper carrier, heat moves out fast. According to GaN-on-SiC RF device data, this material set supports higher power density with fewer thermal bottlenecks. No kidding—this is the same tech used in military radar.

Instantaneous Wideband Coverage

You do not need to retune or switch bands. The module covers 700-900 MHz in one continuous sweep. Output power is a steady 50±1 dBm, and the 50-ohm match is maintained on both N-female ports. With an analog scan speed of 270 KHz, it can hop across the band quickly enough to disrupt frequency-hopping drone links. That’s a big deal for counter-UAS work where targets change channels fast.

Built-In Noise Source in the 100W GaN Jamming Module

No external waveform generator? No problem. This unit ships with a high-speed noise source already on board. Feed it 28 V and a trigger, and you are jamming. If your mission calls for something else, the factory can swap in a VCO, DDS, or SDR source. Custom scan speeds from 100 to 500 KHz are also available. See our RF jamming amplifiers category for similar power levels and lower bands.

Thermal Design That Survives Field Use

At 100 W output, heat is always a concern. But the copper base and patented thermal vias spread the load so well that the module runs reliably from -20°C to +65°C without derating. The 150×80×22 mm housing acts as a secondary heatsink. In many fixed or vehicle-mounted setups, passive airflow is all you need. No liquid cooling, no fans.

Size, Weight, and Mounting

800 grams. That is the total weight. You can mount two modules back-to-back for dual polarization or higher ERP and still stay under two kilograms. The small size means it fits in portable cases, drone-defense trailers, or tower enclosures without redesigning your entire RF chain. Standard N-female connectors make swapping units quick.

Power Budget and System Integration

The module runs on 28-32 V DC and draws up to 9.2 A at full power. Use a regulated supply rated for at least 10 A, and keep cable runs short with thick wire. Status LEDs for power, over-voltage, and over-temperature give you instant feedback. No negative bias supply is needed—internal sequencing handles everything.

Reliability and Customization

Every unit goes through load-pull and thermal cycling before shipping. The AB-class bias network is protected against brief open or short conditions at the output, though a proper 50-ohm load is always recommended. Most custom orders—different scan speeds, modulation sources, or connector types—take five to seven business days. Field return rates sit below 0.3% over 18 months.

Why This Module Replaces Bulky Rack Units

From fixed-site drone defense to mobile counter-UAS kits, the 100W GaN jamming module in the 700-900 MHz band delivers serious RF power without the usual size and heat penalties. It is a clean drop-in solution for integrators who need broadband disruption now. Compare it to traveling-wave tube amplifiers or rack-mounted solid-state units, and the weight savings alone justify the switch.
