Digital gallium arsenide upgrades for military systems

Digital gallium arsenide (GaAs) integrated circuits (ICs) are manufacturable with sufficiently high integration level, yield, and performance to be of great value to a variety of electronic systems. But, as with every new technology, there are substantial barriers to getting systems designers to use digital GaAs. To address this problem, DARPA has begun a program to demonstrate digital-GaAs-based subsystems that meet the needs of specific fielded military systems. Background information is presented on DARPA's efforts in digital GaAs, the insertion demonstration projects are described, and trends and conclusions from these projects are summarized.<<ETX>>
