Wide-band monolithic modulator in GaAs/AIGaAs-technology

Abstract

GaAs-MMICs are of increasing importance for telecommunications equipment, consumer electronics, and traffic management systems. We have had previously developed, a number of different basic GaAs-IC-modules; many of them operating from almost DC up to 65 GHz. Based on these modules, we have designed, and built a relative complex modulator - MMIC, which operates from 35 GHz up to 65 GHz. Both, simulated and experimental results of some basic modules, and of the successfully operating, wide-band monolithic integrated modulator are given.
