Balanced Photodetector

they are widely used in coherent detection applications for distributed fiber optic sensing, and in scenarios such as wind measurement radar.

Balance Detector 10M-400MHz for OCT, Fiber Optic Sensing Systems, Wind Radar

The balanced photodetector contains two photodiodes and a low-noise transimpedance amplifier, in which the two photodiodes are matched to each other for excellent common mode rejection ratio
