The original design was a simple board with a wire bond package and several peripherals. Competitive pressures required a significant reduction in size and thickness. On top of that, they had to add RF matching to simplify the adoption of the module. Toshiba used Zuken’s CR-8000 Design Force with ANSYS analysis tools to accomplish the project.
