Powerful 150W Anti-Drone Jammer Module: 4.8-5GHz GaN

The 150W anti-drone jammer module is built for counter-UAS teams that need serious output power in the 5GHz band. Covering 4800 to 5000MHz, this unit delivers a full 150 watts of RF energy while keeping a footprint small enough for vehicle-mounted or fixed-site systems. With a built-in high-speed analog sweep source, the module can generate broadband interference without any external signal generator.

GaN Amplifier Core and Efficiency

This module uses a gallium nitride (GaN) power amplifier stage. GaN brings two major advantages: higher power density and better thermal performance compared to older LDMOS designs. Efficiency is rated at 40% or above, which means less wasted heat and smaller cooling requirements. The base material is GaN on silicon carbide (SiC), a substrate known for excellent heat spreading. That matters when you push 150W continuously in hot environments.

The output stage is protected by an internal absorptive VSWR protection device. If an antenna gets damaged or disconnected, the module won’t instantly destroy its output transistors. This is a common failure point in high-power jammers, and the built-in protection saves money and downtime.

Built-In Sweep Source and Signal Behavior

The 150W anti-drone jammer module includes an internal high-speed analog sweep source. This source rapidly sweeps across the 4800-5000MHz range, creating a moving interference pattern that is hard for frequency-hopping drones to avoid. There is no need for a separate DDS or signal generator, which simplifies system design. The output connector is a standard SMA female, rated for high power.

The module maintains an output VSWR of 2.0 or less under normal matched conditions. Input and output impedance are 50 ohms, so it integrates easily with common RF components like circulators, filters, and antennas.

Power, Control, and Integration

Supply voltage is DC 24V to 29V, with a maximum current draw of 15.0A at full output. The enable pin uses simple TTL logic: apply +5V or leave floating to turn the module on, ground it to shut down. Three LEDs indicate power enable, overvoltage, and overtemperature conditions. These indicators help field technicians diagnose problems quickly.

The module measures 168.5mm × 84.5mm × 23mm and weighs only 0.55kg. That is remarkably compact for a 150W GaN amplifier. Multiple modules can be stacked in a single enclosure to cover other drone bands, such as 2.4GHz or 900MHz. For lower-band coverage, see our 30W 1000-1300MHz anti-drone module. According to the Federal Aviation Administration, unauthorized drone activity near airports remains a growing concern. Academic research on RF jamming effectiveness provides additional background on countermeasure strategies.

Thermal Design and Field Deployment

Operating temperature range is -20°C to +65°C, which covers most outdoor deployment scenarios. The GaN-on-SiC baseplate pulls heat away from the active devices efficiently. The overtemperature LED and automatic shutdown protect the module if ambient temperatures exceed safe limits or if airflow is blocked.

For system integrators, this module offers a straightforward path to a high-power 5GHz jammer without building a custom RF chain from scratch. The combination of built-in sweep source, VSWR protection, and LED diagnostics reduces integration time and improves reliability in the field.
