Abstract
Content

NASA’s Glenn Research Center has developed nanoionic-based radio frequency (RF) switches for use in devices that rely on low-power RF transmissions, such as automotive systems, RFID technology, and smartphones. These groundbreaking nanoionic switches operate at speeds of semiconductor switches, and are more reliable than microelectromechanical systems (MEMS) switches while retaining the superior RF performance and low power consumption found in MEMS, all without the need for higher electrical voltages. In this new process, metals are photo-dissolved into a chalcogenide glass and packaged with electrodes and a substrate to form a switch. Since the nanoionic-based switch is electrochemical in nature, it has certain advantages over switches that are mechanically based, including nonvolatility, lack of moving parts that can fail, ease and efficiency of activation, and ease of fabrication. This innovative device has the potential to replace MEMS and semiconductors in a wide range of switching systems, including rectifying antennas (rectennas) and other RF antenna arrays.
