Applications
Preamplifier of an optical receiver circuit for OC-48/STM-16 (2.7 Gb/s (FEC available))
Functional Description
The F0100505B is stable GaAs integrated transimpedance amplifier. Typical Applica-
tions are for 2.7 Gb/s (FEC avaiable) optical receiver circuit, for example, OC-48/STM-16,
instrumentation, and measurement applications. The integrated feedback loop design pro-
vides broad bandwidth and stable operation. The F0100505B typically specifies a high
transimpedance of 1.5 k
(RL=50
) at a typical 2400 MHz O/E bandwidth (-3 dB-cutoff
frequency) with a dynamic range of over 25 dB. It also provides a large optical input overload
of more than +1 dBm. Furthermore, it can operate with a low supply voltage of single +3.3 V.
It features a typical dissipation current of 45 mA.
Only chip-shipment is available for all product lineups of GaAs transimpedance amplifi-
ers, because the packaged preamplifier cannot operate with the maximum performance
owing to parasitic element of the package.
