• This full reverse costing study has been conducted to provide insight on technology data,

manufacturing cost and selling price of the Avago AFEM-8030.

• Avago AFEM-8030 is a front-end module LTE band device aimed at use in Apple iPhone 6s Plus.

• The AFEM-8030 features power amplifier and filtering in different LTE band manufactured with Avago

proprietary film bulk acoustic resonator (FBAR) process and microcap technology.

• The analysis is focused on FBAR BAW filter.

• Microcap corresponds to the wafer level packaging of the FBAR filters. The Microcap process uses

gold plated Through Silicon Vias (TSV) in the cap to report electrical contacts and gold-gold thermo-

compression wafer bonding to ensure an hermetic sealing.

• Based on complete physical analysis of the AFEM-8030 component, this report provides the

manufacturing cost of the BAW filter die. It will be compared to the Qorvo TQF-6405.

• The TQF-6405 have been found also in the Apple iPhone 6s Plus. The analysis of the TQF-6405 is

available in a separate report.

Reverse costing analysis represents the best cost/price evaluation given the publically available data, and estimatescompleted by industry experts.

Given the hypothesis presented in this analysis, the major sources of correction would lead to a +/- 10% correction on themanufacturing cost (if all parameters are cumulated).

These results are open for discussion. We can reevaluate this circuit with your information. Please contact us:
