Applications
Preamplifier of an optical receiver circuit for OC-192/STM-64(10Gb/
s)
Functional Description
The F0100612B is a stable GaAs integrated transimpedance amplifier capable of 27dB
gain at a typical 9GHz 3dB-cutoff-frequency, making it ideally suited for a 10Gb/s optical
receiver circuit, for example, OC-192/STM-64, instrumentation, and measurement applica-
tions. The integrated feedback loop design provides broad bandwidth and stable operation.
The F0100612B typically specifies a high transimpedance of 1.5k
(RL=50
) with a wide
dynamic range of over 20dB. Furthermore, it can operate with a supply voltage of single
+3.3V.
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 capacitance of the package.
