Abstract
Mobile handsets constitute the largest single opportunity for component
suppliers outside the personal computer market. MEMS devices have been
shipping in mobile handsets since 2002, and in addition to the microphones and
bulk acoustic resonators that have dominated the market to date, there are
emerging opportunities for inertial sensors (principally accelerometers) and
several types of RF components including band/mode switches, matching elements
(such as digital varactors), and oscillators.
This report looks at the intersection of mobile handsets and MEMS. How will
the current MEMS applications grow? Where and why can MEMS devices replace
other types of components? What new features can MEMS enable? What are MEMS'
limitations?
