Functional Description
The F0100208B is a stable GaAs integrated transimpedance amplifier capable of 27 dB
gain at a typical 320 MHz 3 dB-cutoff-frequency, making it ideally suited for a 622 Mb/s
optical receiver circuit, for example, OC-12/STM-4, instrumentation, and measurement ap-
plications. The integrated feedback loop design provides broad bandwidth and stable opera-
tion. The F0100208B typically specifies a high transimpedance of 6.5 kΩ(Rs=RL=50Ω) with
a wide dynamic range of over 30 dB. It also provides a large optical input overload of more
than 0 dBm. Furthermore, it can operate with a low supply voltage of single +3.3 V. It features
a typical dissipation current of 25 mA.
Only chip-shipment is available for all product lineups of GaAs transimpedance amplifi-
ers, because the packaged preamplifier can not operate with the maximum performance
owing to parasitic capacitance of the package.
