Dr. Richard RubyAbstract:
Introduced in 2001, Avago (then Agilent) sold over one million filters by 2002. However, this accomplishment is over-shadowed by the more recent observation that Avago stands to sell 3 Billion filters by the end of 2010. To understand this phenomenon and by extension what else can one do with these small AlN piezoelectric resonators, I will cover the mBVD model for mechanical resonators, method of extracting Q and coupling coefficient from mechanical resonators. This leads to an 'apple to apple' Figure of Merit (FOM) comparison between various kinds of mechanical resonators either in commercial production or studied in Academic research programs. This leads to a short discourse on filter design and the FOMs needed to meet customer requirements of steep skirts, low insertion loss and excellent rejection and isolation. Next, I will cover two recent research topics within Avago: Zero Drift Resonators (ZDR) and Coupled Resonator Filters (CRF). The former device is useful for both temperature stable filters and oscillators (I will also cover scaling laws for ZDR --as well as for any mechanical resonator). CRF devices are of interest because a CRF device is intrinsically both a filter and a balun (allowing one to match single-ended to differential). Also, CRF is notable in that it is a serious reduction in die size compared to traditional FBAR filters (which are smaller than their SAW filter counter parts). This talk will start with an overview of FBAR technology.Biography: Rich Ruby started FBAR research at HP Labs in 1993 and has seen it go from Academic curiosity to high volume commercial applications. Rich was made Fellow of IEEE this year and will be awarded the C.B. Sawyer Award at the International Frequency Control Symposium this year as well for his work on FBAR. Rich worked on all aspects of FBAR and the original design and platform has remained the same since 1997. Rich has over 70 patents in the area of FBAR and has been awarded the Hewlett Prize the Barney Oliver Prize and the Samuel Silver Award during his career.
