					 According to the market research firm iSuppli Corp.,
 help may be on the way for iPhone 4 users frustrated
 by dropped calls with the arrival of Radio Frequency
    Microelectromechanical Systems (RF MEMS),
 semiconductors that can improve the performance of
               antennas in cell phones

 Long plagued by technological hurdles and other disappointing setbacks, RF
MEMS are finally ready for the big time, with revenue projected to double in
2010 and more than triple in 2011 From slightly less than $4 million in 2006,
global RF MEMS revenue is anticipated to climb to $8 1 million this year-and
then surge to $27 9 million in 2011, according to iSuppli
 By 2014, revenue will reach a whopping $223 2 million-a far cry from the
industry's extremely modest beginnings "More than 50 percent of cell
phones shipped in 2014 will feature some form of front-end-module tuning
using RF MEMS technology," said Jeremie Bouchaud, Director &
Principal Analyst (MEMS & Sensors) at iSuppli "The implementation of
RF MEMS switches and varactors in mobile phones could help boost the
performance of smart phones like the iPhone 4, which made news headlines
recently because of a problematic antenna that resulted in dropped signal
strength
 RF MEMS are also ideal for impedance matching of the Power Amplifier "
Although other technologies will address antenna issues, including SoS FETs
and BST varactors, MEMS deliver the best performance in terms of insertion
loss RF MEMS switches have been used in small volumes in instrumentation
applications because of their small form factor and excellent RF performance
However, despite initial promise, they failed to take off on a large scale
because of myriad commercialization and technological obstacles
 All that is about to change as RF MEMS technology begins to realize its
potential because of strong product offerings from a number of major suppliers
 Seven firms are sampling RF MEMS products California-based WiSpry Inc
and Japan's TDK-Epcos are offering RF MEMS for high-volume cell
phone applications
On another front, U S firms Analog Devices Inc antenna , Radant
Technologies Inc
 and XCOM Wireless Inc -in cooperation with relay manufacturer Teledyne
Technologies Inc -as well as Japanese supplier Omron Corp are targeting
high-end applications for testing and instrumentation such as ATE and RF test
 U S startups Radant MEMS and MEMtronics focus on defense applications
In particular, interest is growing among mobile handset manufacturers on how
RF MEMS can be used for the front-end tuning of cell phones to improve
antenna performance, given the advent of new wireless standards like LTE for
4G technology
 WiSpry-which has garnered several design wins for its MEMS varactors-is
expected to commence volume production by the fourth quarter last year
Outside of cell phone antennas and instrumentation, a pair of smaller-but still
untapped-opportunities also exists for RF MEMS switches and varactors in the
foreseeable future One of these areas is in wireless infrastructure gear-e g
, for femto cells-and cellular base stations, where the current switches being
used could be supplanted by cheaper and higher-performing RF MEMS
devices Another area is in defense and aerospace applications, including
radio systems and phased array antennas, especially after 2014 This
represents a high-volume opportunity for RF MEMS numbering in the millions
of units
