This paper summarizes and reviews the work and design approach of many groups in the development of the Intel® Centrino® Duo mobile technology Intel® PRO/Wireless 3945ABG Network Connection card for the Intel Centrino Duo mobile technology platform. The combination of taking a top-down approach to the system design, the application of self-calibration schemes, the modularity approach taken in the RFIC design, the use of custom board and FE elements to reduce part count, and the significant improvement of production testing time, has resulted in a reduction of platform integration from 6 to 4 quarters with product yields better than 98.5% with lower product cost and a smaller FF. The same approach is now being applied to our next-generation wireless products.
