KXAT834_8B1L1E1 Anti-jamming integrated machine
The KXAT834_8B1L1E1 anti-jamming integrated machine completes the reception, amplification, down-conversion, filtering and anti-jamming processing of 8 channels of BDS_B1, GPS_L1 and GAL_E1 frequency signals. It is powered by a voltage of +18~+32V and consists of four parts: an antenna array component, a radio frequency component, an anti-jamming processing component and a receiver. It can realize the function of anti-jamming against seven wide-band interferences and achieve high-precision positioning and accurate time service under strong interference conditions.
