and Cavendish Kinetics today announced their collaboration to bring MEMS
tunable RF solutions to the consumer mobile wireless market. The process
technology combines the Cavendish NanoMech? MEMS technology with the
TowerJazz power CMOS process and custom RF interconnect in a single chip
solution. Designed specifically for radio frequency (RF) applications,
the Cavendish NanoMech? MEMS technology has passed rigorous reliability
testing and enables products boasting advantages in size and performance
compared to other technologies. NanoMech? MEMS technology can be
combined with other TowerJazz technologies such as SOI CMOS, SiGe BiCMOS
and Through-Silicon Vias (TSVs) to service a wide variety of emerging
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 Dennis Yost,
President and CEO of Cavendish Kinetics. "TowerJazz has proven its
ability to quickly transfer process technologies and we are now in a
position to supply tens of millions of devices per month to support the
large and rapidly growing 4G/LTE mobile device market," Yost added.
"We are excited to bring the Cavendish Kinetics NanoMech? MEMS devices
into volume manufacturing," said Russell Ellwanger, CEO of TowerJazz.
"The integrated RF MEMS process is strategic for TowerJazz and broadens
our specialty fab leadership position. TowerJazz is a large supplier to
the consumer RF market and the Cavendish relationship expands our market
participation. By combining the TowerJazz high volume manufacturing
capability with the innovative NanoMech? MEMS process from Cavendish, a
highly reliable CMOS-MEMS solution is helping to solve some very
difficult 4G/LTE issues."
