A High Plains Section Sponsored Event
Although FBAR has a large success in the area of filters, both enabling and leading the aggressive mobile phone applications for 4G and 5G LTE; FBAR the resonator, could enable other non-Filter applications.
The first area is low power radios. FBAR enabled radios can reduce the amount of power relative to more traditional radios by eliminating the PLL and using direct modulation at high frequencies. A niche where this is most useful would be the ISM band at 2400 to 2480 MHz. Along with low power radios are the applications of extremely low noise oscillators with jitter measured in the single digit femtoseconds. Beyond radios, there are the possibility of circulators, and wake up receivers.
The second broad area is sensors. Here, the 'jury' is still out. As a mass sensor or, temperature sensor or, pressure sensor or particle detector, etc.. the FBAR is quite attractive. The issue is that the FBAR is very much sensitive to all environmental variables and the challenge will be to 'tease out' the one environmental parameter of interest and ignore all other environmental parameters. This Author has worked with many Universities over the years and has built up multiple examples of promising non-Filter technologies.

Biography:
Rich Ruby (IEEE Fellow) obtained his B.S., MS., and PhD at the University of California, Berkeley in ’77, ’81, ’84 respectively. After his graduate work, he joined HP Labs (later to become Agilent Labs, Avago Technologies, and now Broadcom). In 1993, he started work on Free Standing Bulk Acoustic Wave Resonator devices (FBAR) and has stayed with that technology since. He has made many contributions to the development with innovations centered on the acoustic properties, manufacturability and the packaging of FBAR filters and duplexers. Rich commercialized the first FBAR duplexers HPMD7901 and the 7904 back in 2001 to 2003. The first all-silicon, chip-scale packaged FBAR duplexer was introduced in 2004. He was made Avago Fellow in 2002 and holds that title as well as Director of Technology at Avago/Broadcom. Rich was also awarded Barney Oliver Prize, the Bill Hewlett Award, and the CB Sawyer Award for his work on FBAR technology and was made IEEE Fellow in 2010. Rich was awarded the IAP Prize for 'Industrial Applications of Physics‘ in 2015. In 2018, Rich was recognized as Distinguished Alumni by U. C. Berkeley. Rich has over 90 patents in the area of FBAR devices and has given numerous invited papers. FBAR has since won several industrial awards. Today, Broadcom now ships many Billions of FBAR filters per year.
