50W GaN UAV Jammer Module: Rugged 400-500 MHz Defense

Introduction to the 50W GaN UAV Jammer Module

The 50W GaN UAV jammer module is a compact RF countermeasure block built for the 400-500 MHz band. It delivers 47±1 dBm output from a 28V DC rail and uses a gallium nitride-on-silicon carbide design mounted on a copper heat spreader. The module targets system integrators who need a lightweight, wideband source for counter-UAS, test benches, or spectrum control. With an SMA female connector and 50-ohm matching, it drops into existing RF chains without extra tuning.

Why GaN-on-SiC Powers the 50W GaN UAV Jammer Module

Gallium nitride on silicon carbide provides higher power density and better thermal conductivity than older LDMOS or GaAs approaches. For the 50W GaN UAV jammer module, this means the RF stage can run at full output with less derating. The copper base pulls heat away from the die, so the module stays stable during long jamming sessions. The AB-class GaN design balances efficiency and linearity, which matters for wideband noise and swept signals.

Instant Wideband Coverage

This 50W GaN UAV jammer module covers the full 400-500 MHz range instantly. There is no need for band switching or narrowband tuning. The built-in high-speed noise modulation source generates a ready-to-use jamming signal. The analog scan speed is 270KHz by default and can be customized from 100KHz to 500KHz. For advanced waveforms, integrators can request VCO, DDS, or SDR sources instead.

Compact Thermal Management

The 50W GaN UAV jammer module measures 117x58x18mm and weighs only 300g, making it one of the lightest 50W GaN stages in this band. The copper heat spreader uses a patented method to move heat efficiently. Even with a current draw between 3.2A and 4.5A at 28V, the module runs continuously from -20°C to +65°C. LED indicators show power, over-voltage, and over-temperature status, so field operators can react quickly.

Key Specifications at a Glance

The main electrical parameters of the 50W GaN UAV jammer module include a 400-500 MHz frequency range, 47±1 dBm output, 28V supply (24-28V), ≤3.2-4.5A current draw, built-in noise source, and 117x58x18mm dimensions. The standard scan speed is 270KHz with customization from 100KHz to 500KHz. The RF interface is an SMA female connector with 50-ohm impedance. These values make the module suitable for vehicle, fixed-site, and portable counter-UAS payloads.

Deployment Use Cases

The 50W GaN UAV jammer module fits fixed-site drone defense racks, vehicle-mounted gimbals, and portable spectrum monitoring kits. Its 300g weight and 18mm height allow installation in tight spaces. The wide operating temperature range supports outdoor use. Because the output stage is matched to 50 ohms, standard coaxial cables and antennas can be connected directly.

Integration and Control

System integrators can drop this 50W GaN UAV jammer module into larger counter-UAS systems. The 24-28V supply window works with vehicle batteries and DC power buses. Since the module is instantaneously wideband, basic noise jamming requires no external tuning. For custom modulation, the source can be replaced with a VCO, DDS, or SDR board. 

Compliance Note

High-power RF countermeasure modules are regulated in many regions. Operators must confirm local spectrum authority approvals before transmitting. The 400-500 MHz band may overlap with licensed services. This module is for technical evaluation only. Learn more about gallium nitride on silicon carbide and check FCC rules for RF compliance.
