PHOTODIODE
InGaAs APD
G8931-20
Large active area:
蠁0.2
mm, high-speed response: 0.9 GHz
G8931-20 is a large area InGaAs APD designed for distance measurement, spatial light transmission and low-light-level detection, etc. Despite its
large active area of
蠁0.2
mm, G8931-20 provides high-speed response (typical cut-off frequency 0.9 GHz at M=10).
