The demand for bandwidth in cellphones is driving the industry toward complex RF front-ends that rely heavily on acoustic filters. The main purpose of this talk is to give an overview of filter technologies (SAW, BAW, temperature-compensated SAW), some basic acoustic design techniques (ladder filter, duplexers and multiplexers) and a sense of what to look for when working with filters. We will try to shed some light on the key specifications and trade-offs for RF filters and how they affect the RF front-end of a phone.

Speaker Bio:
Pierre-Alexandre Girard graduated from the Ecole Centralle de Lille (MS, Physics) and the Université de Valenciennes (MSEE) in 2000 and has been designing acoustic RF filters and modules since then. He started his career in Thomson Microsonics, then worked for Thales, Temex, Sawtek, Triquint, TDK and is now a Director of Engineering for Qualcomm, based in Maitland Florida.
