Dual Input EML 43Gb/s Broadband RF 4.5V LN Modulator Driver Amplifier OA4SMM4

Description

The OA4SMM4 is a dual input high performance broadband 43 Gb/s Electro-Absorption

optical modulator driver amplifier with very low jitter, 4.5 V amplitude, with excellent 

gain and group delay flatness, matched to 45GHz. 

It is designed for electro-optical test equipment and SONET OC-768 / STM-256 optical 

modulator driver applications.

Applications

The OA4SMM4 is offered in a small modularized package with superb performance, and 

is intended for lab use or transponder integration. The OA4SMM4 has gain and power 

levels that are ideally suited for driving either 40G electro-absorption modulators. 

The dual driver is well matched so it can be used for differential modulators or with other 

complex modulation schemes. It has low power dissipation, ample drive signal, very low 

added jitter, fast rise/fall times, and is easy to use with simple bias voltages.
