Executive Summary

• This full reverse costing study has been conducted to provide insight on technology data, manufacturing cost andselling price of the Taiyo Yuden Band 7 Duplexer.

• Located in a SiP (Sytem In Package), the filter is packaged along with a power amplifier, SPxT switch and a RF IC. Thedevice is a custom version of a Taiyo Yuden’s commercial device. The duplexer features a SAW filter using sapphireand LiTaO3 substrate, a BAW filter with an original FBAR design using air gap cavity on a silicon substrate and a metalsealing packaging.

• In this report, the complete duplexer is analyzed from the filters to the packaging developed by Fujitsu Media Limitedwho was bought by Taiyo Yuden. The report includes a complete analysis of the package, the SAW filter and the BAWfilter featuring a cost analysis and price estimation for the device. Schematic of the BAW filter is also provided tounderstand the difference between shunt and series cells.

• Finally, it also comprises a complete performances and technology comparison with former generation of the band 7duplexer from Taiyo Yuden and a technology comparison with Qorvo and Broadcom BAW filters and packagingsolutions.
