Features
Low voltage of +3.3 V single power supply
15.5 k
high transimpedance
Typical 250 MHz broad bandwidth
31.5 dB high gain
0 dBm large optical input
Over 35 dB wide dynamic range
Differential output
Applications
Preamplifier of an optical receiver circuit for
OC-3/STM-1 (156 Mb/s)
Functional Description
The F0100106B is a stable GaAs integrated transimpedance amplifier capable of 31.5
dB gain at a typical 250 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 F0100106B typically specifies a high transimpedance of 15.5 k
(Rs=RL=50
)
with a wide dynamic range of over 35 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 24 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.
