Design and Industrialisation of Solidly-Mounted BAW filters


This paper discusses the design of high-Q bulk-acoustic-wave filters that are optimised for integration in to front-end-modules (FEM) for 2G/3G cellular applications. In addition, the industrialisation aspects of BAW filters are presented. A novel low-cost process was developed based on standard IC processing which uses a solidly mounted reflector stack of… (More)
