Functional Description
The F0100109B is a stable GaAs integrated transimpedance amplifier capable of 32 dB
gain at a typical 130 MHz 3 dB-cutoff-frequency, making it ideally suited for a 156 Mb/s
optical receiver circuit, for example, OC-3/STM-1, instrumentation, and measurement appli-
cations. The integrated feedback loop design provides broad bandwidth and stable opera-
tion. The F0100109B typically specifies a high transimpedance of 27 kΩ(Rs=RL=50
Ω)
with
a wide dynamic range of over 40 dB. It also provides a large optical input overload of more
than 3 dBm. Furthermore, it can operate with a low supply voltage of single +3.3 V. It features
a typical dissipation current of 27 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.
