Eight-channel Satellite Navigation Anti-jamming Module DFGR-AR05

概要

The DFGR-AR05 eight-channel anti-jamming module adopts one anti-jamming processor and connects four two-channel ADs to complete digital down-conversion and anti-jamming signal processing respectively, and can output two channels of DAC digital intermediate frequency or I/Q zero intermediate frequency output. DFGR-AR05 eight-channel anti-jamming module can output information such as interference signal status detection and anti-jamming mode according to external control commands, and can be used in conjunction with dual-mode array RF front-end. With 2-channel X4 16bit large dynamic range ADC; High channel isolation and good consistency; With channel individual closing control function; Can monitor the number, strength, azimuth and other information of interference signals; With program online upgrade function; It can realize 8 anti-interference processing, which can be used for BD2 S+B3 anti-interference; Low cost and low power consumption. Suitable for carrier applications such as aerospace, UAV, special vehicles, ships, etc.; Suitable for satellite navigation applications in harsh electromagnetic environments.
