We see from your search that you're looking for information on the term "FBAR",
and we have a large number of manufacturers' news releases and technical articles here on Electronicstalk which will be of interest.
Let me be your guide.
Start with
the news release Quintplexer keeps handset signals distinct from
Avago Technologies, which we summarised at the time by saying "FBAR-based quintplexer module helps designers create ultrasmall high-performance mobile phones that deliver simultaneous GPS functionality".
A few weeks before,
we featured the news release Filtered amp improves GPS reception from
Avago Technologies: "GPS low noise amplifier with integrated filter provides superior reception sensitivity and is ideal for use in handsets, in-vehicle navigation GPS receivers and GPS antennas".
In February 2007, we covered the news from Avago Technologies
concerning its AFEM-7780
- take a look at RF front-end module saves space in handsets
which says: "Module integrates FBAR-based duplexer with advanced power amplifier technology to create the industry's smallest integrated RF front-end module for UMTS Band 1 handsets".
Take a look also at the news release from Avago Technologies, Master Scientist to become IEEE Fellow,
as well as Filter module has five for multifunction handsets from Avago Technologies,
and Duplexers are made for US frequency bands from Avago Technologies.
