iT3042D

iT3042D 40 Gb/s High-Sensitivity Limiting Amplifier Description The iT3042D is a MMIC limiter amplifier for use in 40-Gb/s optical communications systems. Signals at levels as low as +/-25 mVpp differential can be amplified up to 1.0 Vpp differentially. The design allows an offset correction function, output voltage control, and output power monitoring. The inputs are AC and DC coupled and the output is DC coupled.
