Variable Gain Silicon Avalanche Photodetectors PD-SAF-400A

The LBTEK Avalanche Photodetector PD-SAF-400A combines a high-sensitivity Si avalanche photodiode, capable of detecting optical signals from DC to 385 MHz. The silicon avalanche photodetector features a photosensitive detection area with a diameter of 0.2 mm and achieves a peak spectral photoelectric conversion gain of up to 4.2×10e5 V/W. Additionally, the silicon avalanche photodetector allows continuous adjustment of the APD's M multiplication factor, enabling a gain adjustment range of 10-100 times to meet the vast majority of customer testing requirements. Furthermore, the silicon avalanche photodetector includes a special control circuit for temperature compensation of the M factor, ensuring gain temperature stability ≤1.5%. Note: The avalanche photodetector does not support hot-plugging; the detector must be connected to the power supply before powering on.
