50W LoRa FPV Jammer Module: 700–900MHz GaN Power for Countermeasure Systems

The 50W LoRa FPV jammer module is a compact RF power module designed for 700–900MHz countermeasure work. It uses an AB-class GaN design and delivers 47±1dBm, or roughly 50W. The module runs from 28V, draws 3.2–4.5A, and uses 50-ohm input/output. It is built for system integrators who need a small, rugged RF block rather than a full enclosure. The module is not a consumer device. It should be used only where local law allows jamming or countermeasure transmission.

Why 700–900MHz?

This band covers many LoRa links, FPV video, telemetry, and remote-control channels. A 50W module gives extra link margin in difficult sites. It can support fixed installations, vehicle systems, or portable countermeasure units. The wideband design helps cover several sub-bands without swapping hardware. Custom tuning is available for narrower or shifted ranges.

GaN Design and RF Path

The RF stage uses GaN-on-SiC technology mounted on a copper heat sink. That combination helps handle high power in a small package. The AB-class layout supports instantaneous wideband operation. Input and output impedance is 50 ohms, so it matches common RF chains. An SMA female connector is standard. The module includes a built-in high-speed noise modulation source. Default analog scan speed is 270kHz. Customers can request 100–500kHz. For more advanced waveforms, the input source can be customized as VCO, DDS, or SDR.

Power, Control, and Protection

Nominal supply voltage is 28V, with a 24–28V range. Current draw is ≤3.2–4.5A at 50W output. Output power is 47±1dBm. LEDs show power, overvoltage, and over-temperature status. These indicators help protect the module during integration and field use. The control interface is kept simple for OEM designs. The module can be paired with external filters, antennas, or switches, depending on the system.

Mechanical and Thermal Notes

The standard size is 117×58×18mm, and weight is about 300g. Custom dimensions are possible. The copper base is intended for mounting to a larger heat sink or chassis. Operating temperature is -20 to +65°C. Good thermal contact, stable airflow, and a proper 50-ohm load are important. Avoid running the module without a suitable antenna or load. Check VSWR and reduce drive if the over-temperature LED turns on.

Customization Options

Because every countermeasure project is different, the module supports customization. Options include frequency range, scan speed, modulation source, connector type, dimensions, and mounting. This makes it useful for LoRa FPV jammer module developers, RF labs, and authorized defense or security integrators. The module is a building block, not a finished product. Users must add power conditioning, cooling, antennas, and legal safeguards.

Compliance and Safe Use

RF jamming can disrupt critical communications. It is illegal in many countries without government authorization. This module is intended for licensed engineers, approved test environments, and authorized countermeasure programs. Do not use it near hospitals, airports, emergency services, or public networks. The buyer is responsible for compliance with local regulations. Proper shielding, filtering, and power control reduce interference risk. Always document authorization before transmitting.

Final Thoughts

The 50W LoRa FPV jammer module packs 700–900MHz GaN power into a small 300g package. It offers 50W output, flexible modulation, and custom options for OEM integration. For authorized projects, it can be a practical RF building block. For everyone else, it is not a legal or safe tool.
