Abstract

An equalizer using cascode MESFETs in a distributed structure has been designed for pulse shaping data in high speed lightwave systems. Pulse shaping is accomplished by controlling the gain of each individual cascode stage separately in the distributed circuit. The circuit was fabricated in a microwave monolithic integrated circuit (MMIC) implementation using Nortel´s 0.8 /spl mu/m GaAs MESFET technology. Frequency response measurements demonstrate that the bandwidth can be controlled up to 8 GHz. Eye pattern measurements demonstrate the ability to control the pulse shape at 5 Gb/s.
