Functional Description

The F0100504B is stable GaAs integrated transimpedance amplifier. Typical Applications are for 2.5Gb/s

optical receiver circuit, for example, OC-48/STM-16, instrumentation, and measurement applications. The

integrated feedback loop design provides broad bandwidth and stable operation. The F0100504B typically

specifies a high transimpedance of 2.2k

Ω (RL=50Ω) at a typical 1900MHz O/E bandwidth (-3dB-cutoff

frequency) with a dynamic range of over 26dB. It also provides a large optical input overload of more than

+1dBm. Furthermore, it can operate with a low supply voltage of single +3.3V. It features a typical dissipation

current of 50mA.

Only chip-shipment is available for all product lineups of GaAs transimpedance amplifiers, because the

packaged preamplifier cannot operate with the maximum performance owing to parasitic element of the package
