Product Description
The ANADIGICS AMT8302 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 TO56 flat window packaged
receiver pass stringent reliability requirements.
These products are readily designed into
receiversand transceivers for 2X Fibre Channel
applications.
