40 Gb/s, 3 volt InP HBT ICs for a fiber optic demonstrator system

Abstract

We have designed and fabricated an InP HBT chip set intended for a 40 Gb/s fiber optic demonstrator system. The chip set consists of 14 different digital- and analog-ICs, and the project is a joint-venture between Ericsson Microwave Systems AB and Hughes Research Laboratories. The project goal is to demonstrate 40 Gb/s fiber optical operation, to learn how to design very high speed/high frequency integrated circuits, and to expand our knowledge on circuit behaviour prediction.
