Expectations of the use of RF MEMS devices for mobile phone applications have gone through many cycles of hope and disappointment. We may now be finally entering in the mass adoption phase with the first high-volume application, WiSpry’s MEMS based tunable impedance matching device, incorporated in one of Samsung's new phones.
RF MEMS devices promise to bring significant benefits to both consumers and cell phone network operators. These benefits include fewer dropped calls, faster data transmission rates, improved reception and enhanced power efficiency. Use in mobile phones and tablets is projected to expand the RF MEMS market by a factor of 200 by 2015, according to IHS iSuppli. Sales of RF MEMS devices are expected to increase from $720,000 in 2011 to a projected $150 million in 2015.
DelfMEMS, an RF MEMS switch developer based in France, is expected to be among the players in this rush to commercialize RF MEMS devices for handset and tablet applications. MEMS Journal recently interviewed Olivier Millet, founder and CEO of DelfMEMS. We discussed the challenges involved in integrating RF MEMS devices into handsets, viable insertions points, product roadmaps, and competition from MEMS and non-MEMS technology providers.
