3 Executive Summary o Executive Summary o Reverse Costing Methodology This full reverse costing study has been conducted to provide insight on technology data, manufacturing cost and selling 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. The device is a custom version of a Taiyo Yuden s commercial device. The duplexer features a SAW filter using sapphire and LiTaO3 substrate, a BAW filter with an original FBAR design using air gap cavity on a silicon substrate and a metal sealing packaging. In this report, the complete duplexer is analyzed from the filters to the packaging developed by Fujitsu Media Limited who was bought by Taiyo Yuden. The report includes a complete analysis of the package, the SAW filter and the BAW filter featuring a cost analysis and price estimation for the device. Schematic of the BAW filter is also provided to understand the difference between shunt and series cells. Finally, it also comprises a complete performances and technology comparison with former generation of the band 7 duplexer from Taiyo Yuden and a technology comparison with Qorvo and Broadcom BAW filters and packaging solutions by System Plus Consulting Taiyo Yuden Duplexer Technology : SAW & BAW Filter 3
