064 Gb/s) 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 T46F TO-46 Ultra Flat Window Package T46L TO-46 Lens Package 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.
