Product Description:
The ultra-small four-element anti-jamming antenna measures only 65mm*65mm*19.5mm, supports the four-element broadband anti-jaming function of the Beidou-3 B1/L1 frequency point, and can reject various broadband and narrowband rejection jamming such as harmonics, sweep frequency, pulse, frequency modulation, phase modulation, etc. In the B1/L1 frequency band, the antenna integrates an active anti-jamming receiving antenna, which includes core components such as anti-jamming RF chip, intermediate frequency filter, ADC, anti-jamming digital baseband processing, and DAC.
Main Function:
1. Receive satellite signals from GPS-L1 and BDS-B1.
2. It can reject various types of broadband and narrowband jamming such as harmonics, sweep frequency, pulse, frequency modulation, amplitude modulation, phase modulation, etc. for GPS-L1 and BDS-B1 frequency bands.
3. With software online upgrade function.

Intergration Instruction
When integrating the ultra-small four-element anti-jamming antenna and connecting the corresponding interfaces of the ultra-small four-element anti-jamming antenna to the power interface module, please note the following:
1. The ultra-small four-element anti-jamming antenna module has high overall power consumption, so pay attention to the power supply current design during integration.
The ultra-small four-element anti-jamming antenna module has high overall power consumption, so pay attention to the heat dissipation design during integration.
