Description
The Anti–Jamming Integrated Device performs the reception,amplification, down–conversion, filtering,and anti–jamming processing of 7-channel BDS_B1,GPS_L1,and GAL_E1 frequency signals. It operates with a power supply voltage range of +18V to +32V and consists of four components: an antenna array unit, an RF unit, an anti-jamming processing unit, and a receiver. The system provides anti-jamming capability against seven wideband interferences, enabling high-precision positioning and accurate timing even in strong interference environments.
Product Features and Applications
This anti-jamming integrated terminal features a highly integrated frequency signal processing module, characterized by low noise figure, high gain, excellent channel consistency, and low mutual coupling. The product is compact in size, low in power consumption, simple to deploy, and exhibits strong electromagnetic compatibility. It is suitable for widespread application in mobile vehicles, ships, aircraft, unmanned platforms, and other fields, significantly enhancing their anti-jamming performance.
