Ф1.8mm 905nm Silicon avalanche photodiode     


Si avalanche Photodetector module integrates low-noise APD detector, low-noise broadband transimpedance amplifier, ultra-low noise isolation power supply, high-voltage power supply; isolation power supply ensures that the output signal is not affected by external power supply; APD temperature compensation improves the stability of detection module. Avalanche photodetectors are characterized by high gain, high sensitivity, high bandwidth and low noise.

Note :

C1 - filter capacitor, mainly to filter out the noise of the bias working voltage VR; 

C2 - bypass capacitor, mainly to provide a ground loop for the AC signal;

R1 - current limiting resistor, mainly to protect the detector from being damaged when the bias working voltage VR is too high;

Ri-sampling resistor, which converts the photocurrent into a voltage signal.
