Linear Modulator Driver Is In For The Long Haul

Integrated Device Technology’s 46 Gb/s, SMT quad-channel linear modulator driver supports 200G and 400G long haul and metro applications. The driver integrates four linear driver channels in a high-performance surface mount package for direct connection to an OIF-compliant LiNb2O3 modulator.

 

Differentiated by wide bandwidth, low power dissipation, and linearity characteristics, the GX74470 measures 14 mm x 9.1 mm and integrates high frequency chokes and DC blocks for RF inputs and outputs and an individual peak detector for each channel. It provides 35 GHz of 3 dB bandwidth and a 4.5-Vp-p linear output voltage with a power consumption of 1.3W per channel. Linearity is approximately 3%, even for input signals of 700 mVp-p.
