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.
