300M InGaAs Balance Photodetector

300M InGaAs Balance Photodetector

The high-speed low-noise photonic balanced detector module integrates two matched low-noise analog PIN detectors, a low-noise broadband transimpedance amplifier, and an ultra-low-noise power supply. It features high gain, high sensitivity, high bandwidth, low noise, and a high common-mode rejection ratio (CMRR), effectively reducing common-mode noise in the signal and improving the system's signal-to-noise ratio (SNR).

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

Part Number：MP-BPD-M-I-300-F/S-D/A

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