Product Description

The ANADIGICS AMT8301 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 and TO46

lens packaged receiver pass stringent reliability

requirements. These products are readily designed

into receivers and transceivers for 2X Fibre Channel

applications.
