PRODUCT DESCRIPTION
The ANADIGICS AMT121302, packaged in a TO46
flat window or lens can, is a 5V integrated
photodetector and transimpedance amplifier (TIA)
used to convert a long wavelength (1270-1560nm)
input optical signal into a differential output voltage,
and is manufactured in ANADIGICS 6 GaAs wafer
fabrication facility. The TIA maximizes the
receiver performance by providing a negative voltage
to reverse bias the photodetector which allows the
device to achieve high sensitivity and wide bandwidth.
These products are readily designed into receivers
and transceivers for Gigabit Ethernet and Fibre
Channel applications.
