May 4, 2011 — DelfMEMS, RF MEMS player, has delivered custom samples to telecom operator NTT DOCOMO Inc. DelfMEMS provided arrays of custom micro electromechanical system (MEMS) ohmic switches to enable tunability into radio frequency (RF) frontend modules (FEM) for mobile applications. Voltage, size, losses, isolation, ultra-fast switching time and power handling will be evaluated by NTT DOCOMO according to the 6GHz requested specifications.

DelfMEMS is setting up an open technology platform to propose a new integrated micro-mechanical building block based on a new IP portfolio that solves RF MEMS ohmic switch issues. MEMS switching can reduce power consumption and bill of materials (BOM) by minimizing losses between the antenna and active devices of a FEM.

"We are working on a very basic approach" for RF MEMS, said Olivier Millet, CEO. NTT DOCOMO’s validation of these custom MEMS arrays should increase data transfer and decrease power consumption from handsets to base stations. Current insertion losses of DelfMEMS’ MEMS switches are better than advanced SOI or SoS technologies, added Millet, saying that the company is continually looking to decrease them, lower costs, and shrink sizes.

DelfMEMS develops and markets radio frequency switches based on MEMS technology. Learn more at www.delfmems.com.
