We see from your search that you're looking for information on the term "Duplexer",
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 Mobile duplexer cuts size and losses from
Avago Technologies, which we summarised at the time by saying "Boasts best in class transmitter insertion loss to minimise power consumption and superior receiver insertion loss for excellent receiver sensitivity".
Several months prior to that,
we featured the news release Switch makes sense of handset signals from
Peregrine Semiconductor: "Device combines four independent high performance RF switches on a monolithic flip-chip IC controlled by a single onboard CMOS controller".
In June 2007, we covered the news from Avago Technologies
concerning its ACFM-7102
- take a look at Quintplexer keeps handset signals distinct
which says: "FBAR-based quintplexer module helps designers create ultrasmall high-performance mobile phones that deliver simultaneous GPS functionality".
Take a look also at the news release from Zoran Corporation - Imaging Division, Driver-development kit in all-in-one printers,
as well as Modules help streamline 3G designs from Anadigics,
and SAW duplexers shrink to chip-size packages from Kyocera Corp.
