HRL Scientists Demonstrate World's First Millimeter-Wave Flexible Electronics Technology

MALIBU, Calif., July 31, 2013—HRL scientists have demonstrated the world’s first InP-based millimeter-wave flexible electronics technology. “Flexible and printable electronics have received a great deal of attention in the past decade mainly at frequencies below 1 GHz for consumer electronics and RFID (Radio-frequency identification) products. The main attributes for the technology include low-cost manufacturing through roll-to-roll processes, lightweight, mechanical reliability, and bendable for irregular surfaces. High frequency flexible/printable electronics technology is a key enabler for many demanding electronic systems such as conformal phased array radars. In order to address the paradigm shift specifically for microwave and millimeter-wave frequencies and to get similar circuit performance as a bulk semiconductor material, HRL has developed the novel technique to fabricate flexible/printable circuitry,” noted HRL Senior Research Staff Scientist Hasan Sharifi.

InP HEMT technology was utilized to demonstrate the first W-band completely flexible low-noise amplifier (LNA) with 10dB gain per stage. The researchers’ finding was presented at the IEEE International Microwave Symposium (IMS2013) in June 2013 in Seattle, WA titled “First Demonstration of W-band Millimeter-Wave Flexible Electronics”.
