TowerJazz and Cavendish Kinetics Collaborate to Deliver High Volume Tunable RF MEMS Products for Fast Growing 4G Mobile Market
Industry analyst forecasts MEMS market to reach
Cavendish is shipping antenna frequency tuning products to strategic partners for sampling to end customers. These products address challenges with 4G/LTE in achieving its theoretical data throughput. Historically, performance has been limited for several reasons. The increasing number of features in phones and increasing number of frequencies supported require more components and antennas. The increasing size of displays creates a ground plane that blocks the antenna signal and limits performance. To address these trends which lead to further RF performance degradation, the Cavendish components are used to dynamically tune antennas. Because the Cavendish components have an Equivalent Series Resistance (ESR) comparable to a passive component without needing a lossy RF switch, designers can incorporate the components to perform Antenna Frequency Tuning (AFT) in mobile devices. AFT changes the resonant frequency of the antenna and enables much higher antenna efficiency. RF switches, both discrete and solid state, can reduce efficiency by up to 50% when used for AFT. Eliminating the switch, and instead implementing the tunable solutions, dramatically improves overall RF system performance.
Higher demands on LTE mobile devices for better reception of wireless broadband signals is driving the need for this next generation solution. The Cavendish device improves the quality of RF signal by using a large array of bi-state MEMS capacitors on a CMOS chip to provide a variable capacitance to the RF circuit. This class of components addresses needs for: antenna frequency tuning, antenna impedance matching, tunable power amplifiers, and tunable filters.
Fabrication of these tunable solutions, as done at TowerJazz, includes standard CMOS processing steps, but uses a novel and differentiating technique that encapsulates the MEMS elements inside tiny micro-cavities to isolate the moving parts from the outside world. The encapsulation is performed within the semiconductor wafer fab process, not at packaging assembly facilities.
“We have aligned with a strong manufacturing partner with an established
track record and known capabilities to deliver robust and reliable
products in a high volume manufacturing environment,” said
"We are excited to bring the Cavendish Kinetics NanoMech™ MEMS devices
into volume manufacturing," said
