Description
Anti-Jamming Integrated Device accomplishes the reception, amplification, down-conversion, filtering, and anti-jamming processing of 4-channel BDS_B1, GPS_L1, and GAL_E1 frequency signals. It operates with a power supply voltage range of +12V 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 three wideband interferences, enabling high-precision positioning and accurate timing even in strong interference environments.
Product Features and Applications
This anti-jamming antenna features a highly integrated frequency signal processing module, offering low noise figure, high gain, excellent array element consistency, and low mutual coupling. With a compact size, low power consumption, and simple application, it is widely suited for use in mobile vehicles, ships, aircraft, unmanned platforms, and other fields, significantly enhancing anti-jamming performance.
