25GHz LiNbO3 Modulator Driver, Dual Channel Wide Band Amplifier

25GHz LiNbO3 Modulator Driver, Dual Channel Wide Band Amplifier,

The driver amplifier is a general-purpose broadband amplifier designed especially for  Mach-Zehnder optical modulator driver applications. Its exceptional performance and small size make it an easy addition to your Intermediate Reach, Long Haul, or Ultra Long Haul network infrastructure design. It provides a complete driver module package with a wide frequency range of 30 kHz to 25 GHz, low power dissipation, ample drive signal, very low added-jitter, fast rise time, and external control.
