Researchers are using microelectromechanical system (MEMS) technology to develop a single-chip RF circuit that integrates discrete functions to reduce weight and cost, according to a Frost & Sullivan report.

"Over time, this integration can lead to the replacement of all passive RF chips with added functions including Internet connectivity chip devices, reducing form factors. The goal in applying RF MEMS is to propagate the device-level benefits up to the system level," said Frost & Sullivan technical analyst Rajesh Kannan.

MEMS-based components deliver superior RF performance and tunability, over broader operating frequencies. An RF MEMS switch, for instance, provides improved insertion loss, isolation and linearity.

RF MEMS technology is best suited for wireless appliances operating in the home/ground, as well as mobile and space applications such as handsets, base stations and satellites. The technology's low power consumption and reconfigurability makes ubiquitous wireless connectivity possible, Kannan added.
