WiSpry, a company specializing in tunable RF semiconductor products, has declared that its dynamically tunable antenna technology is the basis of the first bulk-produced RF-MEMS-enabled handset.
A leading manufacturer has selected WiSpry’s novel antenna tuner and has started its production. The antenna tuner widens usable bandwidth for small footprint antennas and is capable of compensating dynamically for interference from finger and hand placement even if the antenna is touched physically by users.
WS2017 Tunable Impedance Match circuit of WiSpry includes a low-loss inductor network and the company’s low-loss, digitally-tunable MEMS capacitors. The follow-on impedance-transforming network is capable of compensating dynamically for VSWR up to 20:1 or more in this application. The network set up is managed through a serial bus and constantly updated corresponding to the radio signal.
Mobile-phone OEMS can now design low-volume antennas that can meet the demand of consumers for ultrathin smart phones, thanks to WiSpry’s technology. With the help of an antenna tuner, the amount of energy required for a specific radiated signal can be reduced, which in turn extends the usage time of handsets between charging. Major carriers now offer mobile phone models featuring this technology in many major markets.
According to the Founder and President of WiSpry, Jeffrey Hilbert, the company’s WS2017 helps OEMs to deliver unprecedented benefits in terms of efficiency and performance. Hilbert added that RF-MEMS will turn out to be a key element for OEMs and operators due to the ever-increasing pressure to offer the advanced 4G experience.
