Cavendish RF MEMS released to manufacturing
Additionally, the parts have passed standard JEDEC and SEMI qualification and select Mil-Std 883D and IEC tests.
The CK301 RF MEMS tuner is being manufactured for Cavendish by specialist foundry Tower Semiconductor Ltd. (Migdal Haemek, Israel) using a high voltage CMOS process with RF interconnect and the part has now been released for volume production.
The CK301 is an RF tuner IC that uses MEMS switches to tune capacitance and inductance on the device. The CK301 is used to tune a generic antenna to the multiple frequency bands and operating modes required of 4G/3G smartphones. Antenna tuning is one of the most promising solutions to enable multiband antenna performance, but existing tuning solutions do not provide the characteristics required to make it work efficiently.
Cavendish’s RF tuners provide an industry-leading ‘Q-Factor’ of greater than 200, while only requiring a package of 2 square millimeters area.
Cavendish’s upcoming MEMS products will address the performance needs of LTE-advanced RF front-end components such as power amplifiers, filters and switches, to enable demanding next generation LTE carrier-aggregation and WiFi co-existence solutions.
"We have dedicated ourselves to build RF MEMS products that are optimizing smartphone radio platforms, and can be mass produced using basic CMOS processes," said Dennis Yost, CEO of Cavendish Kinetics, in a statement. He added that Cavendish is now in a position to supply many tens of millions of devices per month to support the LTE mobile device market.
