We see from your search that you're looking for information on the term "Duplexers", 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 SAW duplexers shrink to chip-size packages from Kyocera Corp, which we summarised at the time by saying "Small, lightweight surface acoustic wave (SAW) duplexer has a built-in matching circuit featuring improved attenuation and isolation characteristics". A few weeks before, we featured the news release Chinese microwave devices come to the UK from Gigahertz Marketing Solutions: "Eleading Technologies is now represented in the UK and Republic of Ireland by Gigahertz Marketing Solutions".
In September 2006, we covered the news from Euroquartz concerning its Caiqin Electronics dielectric microwave filters - take a look at Dielectric microwave filters range up to 3.5GHz which says: "Euroquartz has extended the capabilities of its filter product line with the introduction of a new range of dielectric microwave filters".
Take a look also at the news release from Avago Technologies, Duplexers are made for US frequency bands, as well as Filter shipments top 200 million from Avago Technologies, and Handheld analysers promise benchtop accuracy from Anritsu (UK).
