80W GaN Drone Jammer Module 870–960MHz | Analog Sweep

Overview

This 80W GaN drone jammer module covers 870–960 MHz and combines a high-power amplifier with a built-in high-speed sweep source. It is an analog interference module for counter-drone, FPV link disruption, and RF testing. The compact housing measures 168.5 × 84.5 × 23 mm and weighs about 0.57 kg, so it fits into portable and rack-mounted systems. An SMA female output connects to standard 50 Ω antennas and cables.

GaN Power Stage

The RF power stage uses gallium nitride technology. It delivers 80 W typical output with output VSWR ≤2.0. Efficiency is ≥35%, which helps reduce heat compared with older amplifier designs. Even so, the module needs airflow or a heatsink during long transmissions. It runs from DC 24–29 V and draws up to 10.0 A. This makes it suitable for vehicle, backpack, or fixed installations where a stable 24 V bus is available.

Built-In Analog Sweep

A high-speed sweep source is built into the module. It creates analog interference across the 870–960 MHz band without an external signal generator. This is useful when the target uses frequency hopping or wideband links. The module covers common drone control and video frequencies in the 900 MHz region. System designers can pair it with filters or directional antennas to shape coverage and reduce unwanted radiation.

Control and Protection

On/off control is simple. Apply +5 V or leave the control line floating to turn the module on. Ground the control line to turn it off. Three LEDs show power, over-voltage, and over-temperature status. The output includes an absorption-type VSWR protection device, which helps protect the amplifier when the antenna match is poor. The operating temperature range is -20 to +65 °C.

Integration Notes

Keep RF cables short and use 50 Ω components. Mount the module on a metal surface for heat transfer. Do not run it without a suitable antenna or load. Use a power supply that can deliver 10.0 A continuously at 24–29 V. Because the module emits strong RF energy, check local rules before use and keep people away from live antennas. With proper cooling and filtering, it can serve in anti-drone systems, security setups, and RF jamming research.

Applications

This 80W GaN drone jammer module can be used in anti-drone systems, prison or border security, event protection, and RF immunity testing. It can also act as a high-power source for lab work in the 870–960 MHz range. The analog sweep mode is useful for blocking multiple narrowband links at once. For fixed sites, connect it to a sector or omni antenna. For mobile use, a directional panel antenna can increase effective range toward a known threat direction.

Thermal and Power Planning

Efficiency is at least 35%, so a large part of the input power becomes heat. At 24 V and 10 A, input power can reach 240 W. That means the cooling system must handle significant thermal load. Use a fan, cold plate, or large heatsink. Keep air paths clear. If the over-temperature LED turns on, reduce duty cycle or improve cooling. A clean 24–29 V supply with low ripple is also important for stable RF output.

Why Choose This Module

The main advantage is integration. Instead of buying a separate amplifier, sweep source, and protection board, you get one compact RF block. The GaN design gives high power density, while built-in VSWR protection lowers the risk of damage from bad loads. The SMA female output is common and easy to adapt. LED feedback makes troubleshooting faster during field tests.
