Upcoming IEEE SCV EDS Evening Meeting:

Tuesday, July 22, 2008 IEEE SCV EDS Meeting:

"FBAR Filters and Resonators for Frequency and Time Applications"

Speaker: Dr. Rich Ruby, Avago Tech.
Subject: "FBAR Filters and Resonators for Frequency and Time Applications"
Location: National Semiconductor, Building E1, Conference Center,
2900 Semiconductor Drive, Santa Clara, CA 95051.
See the NSC Campus driving directions
and the NSC Building E location map
Time: 6:00 PM - Pizza , 6:15 PM - Lecture
Speaker Contact: Sandeep Bahl

Abstract:

This talk will be in 3 parts; part one will be a quick overview of a novel and general method of measuring Q for any kind of resonator. Comparisons between FBAR, SAW/SMR-BAW, AlN Contour Mode or Rayleigh-Lamb resonators, and electrostatic MEM “whispering gallery” mode resonators will be made and four “Figure-of-Merit” values will be presented.

Next section will cover FBAR filter technology (background and current status) at Avago. In late 2000 Agilent’s Wireless Semiconductor division (now Avago) sold its first PCS duplexer that enabled the Sanyo Slim phone the first “non-brick” sized CDMA cell phone on the market. Since then, Avago’s Wireless Semiconductor Division has sold approximately one billion filters and FBAR is finding more and more applications within the filtering community.

Last section will cover the next market for FBAR: The Temperature Compensated FBAR. This device uses a mechanical layer integrated into the acoustic stack to give temperature stability comparable to quartz resonators. This section will cover both resonator and oscillator measurements for a variety of resonators over a range of frequencies.

Biography:

Rich Ruby started FBAR in HP Labs in 1993 and has driven it to commercial success in the highly visible cell phone market. Rich has over 50 patents issued and another 20 or so patents pending. He is currently Director of Technology and Fellow at Avago’s Wireless Semiconductor Division. He has won numerous awards including the Barney Oliver Award and the Bill Hewlett Award. FBAR has also received much recognition and won Best Product of the Year from such institutes as EDN, Frost&Sullivan, AnalogZone and others. In his spare time, Rich plays violin (his only credential in acoustic technology when he started FBAR) and is married with 3 children.
