KYOCERA Delivers Brazed, Lower Cost LDMOS With Improved Theta JC Using AuSi Die Attach Process

San Diego, CA -- June 21, 2004 -- Kyocera America Inc., the world's leading provider of ceramic RF power transistor packages, today introduced a new line of brazed copper laminate LDMOS packages. These new designs not only offer a lower cost, but also allow users to achieve a 16-18% improvement in Theta Jc when compared to traditional CuW heatsinks. The new package design provides the industry's highest "flange thermal dissipation" utilizing the robust brazed assembly process. The brazed configuration does not require a change from the preferred AuSi die attach process.

Ceramic RF power transistor packages are utilized in the 500 MHz to 3.5 GHz frequency range, and are typically found in cellular / digital base stations, HDTV transmitters, and numerous communication and avionic applications.
