Aeroflex Inc. in Colorado Springs, Colo., is offering radiation-hardened application-specific integrated circuits (ASICs) in 0.25-micron technology for satellite applications. The company completed qualification for the U.S. government Qualified Manufacturing List (QML) class Q and class V production for the devices, called RadHard-by-Design. These ASICs can withstand total-ionizing-dose radiation levels from 100 kilorads to more than one megarad, and have as many as 3 million usable gates, company officials say. Aeroflex officials say they plan to develop 150-nanometer and 90-nanometer radiation-hardened digital technologies, and to introduce analog building blocks for radiation-hardened ASICS with 10-, 5-, and 3.3-volt capabilities.
