400-1100nm Silicon Photoelectric Balanced Detector 350MHz

The high-speed low-noise photoelectric balanced detection module integrates two matched ultra-low noise analog PIN detectors, a low-noise broadband transimpedance amplifier and an ultra-low noise power supply. It has the characteristics of high gain, high sensitivity, high bandwidth, low noise, high common mode rejection ratio, etc. It can effectively reduce the common mode noise of the signal and improve the signal-to-noise ratio of the system. Product model: BPD-Si-100M-B, BPD-Si-200M-B, BPD-Si-350M-B, BPD-Si-500M-B, BPD-Si-1G-B.

Product features：Low noise、 High gain、 High bandwidth、 Compact structure、 Built-in low-noise isolated power supply

Application area：Distributed fiber optic sensing、 Laser wind radar、 Optical coherence tomography、 Spectral measurement、 ns- level optical pulse detection
