cently reported, which is the most complex GaAs integrated circuit reported to date.

GaAs IС technology is being developed to meet important system needs. Advanced systems are faced with challenges which require signifi­cant advances in the rate of real-time signal. At attractive objective is to convert analog microwave signals to digital format in a high-speed A/D converter as close as possible to the microwave receiver front, and then to process the data digitally The bandwidth which can be achieved in GaAs should be capable of permitting digital processing of microwave signals including A/D conversion to become a reality.
