PRODUCT DESCRIPTION
The ANADIGICS AMT128503 is a 3.3V monolithically
integrated Metal-Semiconductor-Metal (MSM)
photodetector and transimpedance amplifier (TIA)
used to convert an 850nm input optical signal into a
differential output voltage, and is manufactured in
ANADIGICS 6 GaAs wafer fabrication facility. The
integrated MSM and TIA receiver maximizes the
receiver performance by minimizing the
photodetector input parasitics to the TIA and

internally biasing the photodetector to achieve high
sensitivity, bandwidth and overload performance. As
an integrated product the reliability is inherently
better than a discrete solution, and both the MSM-TIA
integrated circuit and TO46 flat window, TO46 lens
and TO56 flat window packaged receiver pass
stringent reliability requirements. These products
are readily designed into receivers and transceivers
for Gigabit Ethernet and Fibre Channel applications.
