WiSpry to demo first-to-market single-chip antenna tuning solution

Mobile World Congress 2012, IRVINE, USA: WiSpry Inc. will demonstrate its first-to-market, single-chip CMOS RF MEMS mobile handset solution at the 2012 GSMA Mobile World Congress (MWC). WiSpry will exhibit alongside other MIPI Alliance members at Hall 7, Stand 7G11.

“WiSpry’s dynamically responsive multiband antenna tuner is a powerful tool for OEMs to avoid notorious performance issues stemming from how end users hold or position their devices during use—ultimately making handsets faster and more adaptable,” said Jeff Hilbert, president and founder of WiSpry. “Our product also supports low-volume antennas for ultrathin handsets and reduced energy consumption for radiated signals. In all, WiSpry gives OEMS an extraordinary amount of headroom to deliver faster, thinner and more energy-efficient smartphones and other devices well into the future.”

WiSpry recently announced its technology is at the core of the first mass-produced RF-MEMS-enabled handset from a tier-one OEM. The technology in question, WiSpry’s WS2018 Tunable Impedance Match (TIM) circuit, is a network of digitally-tunable, low-loss RF-MEMS capacitors combined with low-loss inductors. 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 MIPI Alliance RFFE serial bus and continuously updated in sync with the radio signal to achieve an optimum signal at all times.

MIPI Alliance, an industry-leading mobile interface standards organization, will feature 18 member companies in its MWC stand, all of which represent the mobile device ecosystem. In addition to WiSpry, other participating companies include Agilent Technologies, Analogix, Cadence, HDL Design House, Infineon Technologies AG, LeCroy, Mixel, Inc., Nujira Ltd., Quantance, Inc., Renesas Electronics Corp., Sequans Communications, Silicon Line GmbH, ST-Ericsson, Synopsys Inc., Texas Instruments, Toshiba and VLSI Plus.
