Abstract
In this paper, we present the design, fabrication and measurements of an ultra broad band amplifier with 92 GHz cut-off frequency intended for ETDM transmission applications over 40 Gbit/s. The circuit is based on InP double channel HEMT technology developed in OPTO+ to get high frequeny-breakdown voltage product. We will discuss the use of coplanar wave-guide lines and low impedance bias micro-strip transmission lines in such a design. We will also highlight the need of largest bandwidths for 40 Gbit/s eye diagram quality and the needed gain bandwidth for 80 Gbit/s ETDM communications.
