Analysts Sniff Out First Use of RF MEMS Part
IHS iSuppli Teardown Service has identified a radio frequency microelectromechanical-systems (RF MEMS) device, which many experts believe will be the next big thing in cell-phone radios, in a Samsung cell phone. Deemed the first known use of such a part in a mass-market product, the finding sets the stage for RF MEMS growth by a factor of 200 by 2015. According to IHS iSuppli Teardown Service, the Samsung Focus Flash Windows smart phone employs a MEMS-based antenna tuning module labeled A2101 in a die-on-LGA (low-gain antenna) package near the antenna connectors. The tunable impedance match device, as WiSpry dubs it, is a network of inductors combined with CMOS-based, digitally tunable low-loss MEMS capacitors. The WiSpry single-chip design integrates logic circuits/serial interface for control, a high-voltage charge pump, and high-voltage MEMS drivers.
