High Power Developments Emphasize Semiconductor Materials

Microwave and RF power device news has been dominated recently by advances in semiconduc -tor materials. Each new material has perfor-mance capabilities that give it advantages in one or more areas such as frequency, efficiency, linearity, reliability or thermal performance. In this report, we present the descriptions of several materials from the companies that are manufacturing and marketing devices that use those materials. While these comments are marketing-driven, taken together, they provide a picture of these various areas of technolo-gy, and identify key performance features of each. This information was obtained from Web sites and other infor-mation that the companies have made public.
