Description
The Anti-Jamming Integrated Device supports the reception, down-conversion, and amplification of 8 channels of BDS_B1, GPS_L1, and GAL_E1 frequency signals. It combines and forwards the interference-filtered RF signals to the receiver. With a compact size, low power consumption, and simple integration, it features advanced adaptive anti-jamming capabilities. This product is widely suitable for mobile vehicles, aircraft, unmanned platforms, and other applications, significantly enhancing anti-jamming performance.
Product Features and Applications
This anti-jamming integrated terminal features a highly integrated signal processing module for BDS_B1, GPS_L1, and GAL_E1 frequency bands, characterized by low noise figure, high gain, excellent array element consistency, and low mutual coupling. The antenna assembly and receiver offer independent interchangeability. Employing spatio-temporal adaptive anti-jamming technology, it can simultaneously counteract up to seven combined interference sources from different directions and of varying types.
