A 10 Gb/s AlGaAs/GaAs HBT high power fully-differential limiting distributed amplifier for III-V Mach-Zehnder modulator

High power, high frequency linear distributed amplifiers are available commercially which provide single-ended drive capability from a single-ended source. The purpose of this paper is to present an AlGaAs/GaAs HBT high power fully-differential limiting distributed amplifier operating at 10 Gb/s. The amplifier is designed to drive a III-V Mach-Zehnder modulator also developed at Bell-Northern Research.
