January 11, 2012 – BUSINESS WIRE — WiSpry Inc., tunable radio frequency (RF) semiconductor maker, confirmed that its RF micro electro mechanical system (MEMS) technology is used in the first mass-produced RF-MEMS-enabled handset. WiSpry’s antenna tuner extends usable bandwidth for small form-factor antennas, dynamically compensates for user interference such as hand placement that touches the antenna, and lowers the energy required for a given radiated signal.
The design win was first reported in an IHS iSuppli teardown, detailed in RF MEMS tuned for growth, shows smartphone win. IHS expects this component to kick off a slew of RF MEMS integration, supplied from established companies (Sony) to start-ups (DelfMEMS).
WiSpry’s WS2017 tunable impedance match (TIM) circuit comprises a network of low-loss inductors combined with WiSpry’s digitally tunable, low-loss MEMS capacitors. In this application, the resulting impedance-transforming network can dynamically compensate for VSWR up to 20:1 or greater. The setting for the network is controlled via a serial bus and continuously updated in sync with the radio signal.
Jeffrey Hilbert, president and founder of WiSpry, sees RF-MEMS as "an indispensable component in the larger toolkit" for 4G devices.
WiSpry will demo the device all week as part of the MEMS Techzone at International CES 2012 in Las Vegas, Las Vegas Convention Center South Hall 2, booth #25218.
