‘Fbar’
An Electronicstalk guide
Start with the news release FBAR-based bandpass filters for 4G Wimax handsets from Avago Technologies, which we summarised at the time by saying "Avago Technologies has launched two advanced Film Bulk Acoustic Resonator (FBAR) technology-based bandpass filters for next-generation 4G Wimax/LTE handsets, data cards and access points. ". Several months prior to that, we featured the news release FBAR duplexers for mobile handsets and terminals from Avago Technologies: "Avago Technologies has launched a 4G/LTE Band 7 duplexer to its line of high-isolation, 2 x 2.5mm film bulk acoustic resonator (FBAR) duplexers for mobile handsets and data terminals.".
In September 2009, we covered the news from Avago Technologies - take a look at Avago announces highly integrated GPS LNA which says: "Avago Technologies has introduced a highly integrated miniature GPS low noise amplifier (LNA). ".
Take a look also at the news release from Avago Technologies, Avago designs duplexer for UMTS Band 2 handsets, as well as Avago replaces ACMD-7402 with greener version from Avago Technologies, and Front-end modules extend mobile talk time from Avago Technologies.
