  • Abstract
    A nine-tap transversal preamplifier using cascode MESFETs in a distributed structure has been designed for pulse shaping data, AGC and group delay control in high speed lightwave systems. The circuit was fabricated in a microwave monolithic integrated circuit (MMIC) implementation using 0.8 μm GaAs MESFET technology. The AGC capability was demonstrated. The best noise measured for this preamplifier was 15 pA//spl radic/(Hz).
