Applications
Preamplifier of an optical receiver circuit for OC-192/STM-64(10Gb/
s)
Functional Description
The F0100613B is a stable GaAs integrated transimpedance amplifier capable of 29dB
gain at a typical 7.5GHz 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 F0100613B 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
+5.0V.
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.
The F0100613B and F0100614B are various in pad assignment.
