Full-Band RF Spectrum Detection Module with 3km Long-Range
This module is specifically designed for low-altitude safety, covering the entire frequency band from 70MHz to 6GHz. With an omnidirectional antenna, it achieves an effective detection radius of over 1.5 kilometers. It can detect almost all drones (DJI, Autel, Hubsan, FIMI, analog/LTE/Lora links) and provides real-time spectrum output. It is suitable for airport, prison, and major event security scenarios.
The Digital RF Source Module is a programmable wideband signal generation unit designed for multi band amming systems operating in complex electromagnetic environments. It is typicaly integrated with broadband RF power amplifier modules to form a complete UAV countermeasure and communication control solution.With dual RF outputs covering 7o MHz to 6000 MHz, the module supports fast frequency sweeping, adjustable bandwidth up to 400 MHz, and flexible waveform configuration. Software -based control enables precise frequency management, making it suitable for anti-drone systems, electronic warfare applications, and spectrum interference tasks.
Its core advantages lie in its wideband coverage and long-range sensing capabilities. It can accurately identify mainstream drone communication protocols such as DJI DID and Remote ID. Combined with an LNA low-noise amplifier, it improves weak signal reception sensitivity, ensuring stable operation in complex electromagnetic environments.
