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

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.

     Application field
