400-1100nm Si Avalanche Balanced Detector 2GHz

The Si Avalanche Balanced Detection Module integrates a low-noise APD detector, a low-noise broadband transimpedance amplifier, ultra-low noise isolated power supply, high-voltage power supply, and APD temperature compensation. The isolated power supply ensures that the output signal is not affected by external power supplies. APD temperature compensation enhances the stability of the detection module.

Product features：Low noise, High gain、 Built-in low-noise isolated power supply、 Built-in high-voltage power supply、 APD temperature compensation、 Compact structure

Application area：Fiber optic sensing、 Fiber optic communication、 Laser ranging、 Spectral measurement
