Cavendish Kinetics promises to transform the RF stage in mobile phone with its MEMS tunable capacitors. Today the 32CKxxx family is optimized for the antenna tuning function. And Cavendish Kinetics wants to use its SmarTune technology in RF filters and Tx antenna switch.

The Cavendish Kinetics components are integrated in Nubia Smartphones.

With a very small footprint, less than to 2mm², the 32CK417R is the smallest antenna tuner on the market. Moreover, the specific SmarTune technology offers a fine capability to tune the capacitor value, 32 steps between the min and max value to have a seamless tuning. The report provides all details on the structure of the component and the supply chain to produce this astonishing MEMS.

The 32CK417R integrates an ASIC to drive the variable capacitor and thanks to a SPI or MIPI bus communication facilitating the integration for phone manufacturers.

The Wafer Level Packaging, from STATS ChipPAC, reduces the insertion loss, 5x lower than RF SOI solution.

All the wafer manufacturing process, ASIC part and MEMS part, are performed by Tower Jazz.

The report includes a detailed technology and cost analysis describing the innovations of Cavendish Kinetics and TowerJazz of this unique Antenna Tuner.
