BAW filter

Qorvo started as a supplier for Apple’siPhone with the first iPhone 3G. Since thenApple has been integrating Qorvo’s Modulein its flagship. In iPhone 6s series, Appleintegrates Qorvo’s LTE High Band Front-EndModule.The merge of Triquint and RFMD in Qorvoformed a top competitor in wirelesscommunication specially in SMR BAW filter.

Title: Qorvo TQF6405 – SMR BAW High Band FilterPages: 86Date: March 2016Format: pdf + xls

PRICE: Full report: EUR 2,990

Apple integrates in its smartphonethe innovative Solid Mounted Resonators developed by Qorvo

Located on the main board of the Apple iPhone 6s Plus smartphone, theQorvo TQF6405 is a complete Front-End Module for high band LTEapplication. The component is made with several filter dies, assembled on acoreless PCB substrate. It integrates many technology like copper pillar, SMR-BAW filter, proprietary of Qorvo.

All dies present in the component uses TriQuint's proven front-side Cu/Snpillar technology (Cu-Flip™) for simplified assembly and low interconnectinductance, allowing the assembly of all components of the Front-EndModule on the same chip with an area of less than 35 mm².

Specific air cavities are made around each resonator before copper pillarfabrication to preserve any losses.

Thanks to its design and manufacturing process, Qorvo device is notsensitive to temperature and is cost effective in respect to its competitors.

The report includes comparisons with the BAW filter from Avago, also foundin the Apple iPhone 6s Plus.
