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

manufacturing cost and selling price of the Cavendish Kinetics 32CK417R Antenna Tuner MEMS.

• It is the first Antenna Tuner MEMS manufactured by Cavendish Kinetics for consumer applications.

It combines a tunable MEMS capacitor with a controller ASIC in a WLCSP package.

• The 32CK417R component integrates an RF antenna tuner MEMS with a high voltage IC die from

Tower Jazz.

• The RF antenna tuner die comes in a WLCSP from STATS ChipPAC.

• The 32CK417R applications: LTE Smartphones,

Tablets,

Wearable Devices.

It covers the entire set of frequency bands and provides consistently high antenna efficiency,

something impossible with other antenna structures or tuning methods. (Cavendish Kinetics)

The reverse costing analysis is conducted in 3 phases:

Teardown analysis

• Package is analyzed and measured• The dies are extracted in order to get overall data: dimensions, main blocks, pad number and pin out, die marking• Setup of the manufacturing process.

Costing analysis

• Setup of the manufacturing environment• Cost simulation of the process steps

Selling price analysis

• Supply chain analysis• Analysis of the selling price

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

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

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