80 & 200μm InGaAs
Avalanche Photodiode
Preamplifier Module
Description
CMC Electronics’ 264-339757-VAR are using a
low noise InGaAs APD with an ionization ratio of
0.2 with a GaAs FET input transimpedance
amplifier in a 12-lead TO-8 package. The
amplifier internal feedback resistor is listed in
the following characteristics table. Each
amplifier has an overload input protection
circuit for fast recovery. The output can be AC
or DC coupled to a 100 ohm load.

Saturation level vs Background/Backscattering.
The 264-339757-001 will allow operation in presence of high backscattering power normally observed
in the first few kilometers with high power lasers. In the presence of high backscattering, the front end
transimpedance (Zt) is reduced to prevent saturation; however, within nanoseconds it returns to its
original, higher value as the backscattering fades away.
