Researchers Unveil Nanotechnology Circuits for Wireless Devices

Today, IBM (NYSE: IBM) Research scientists announced that they have achieved a milestone in creating a building block for the future of wireless devices. In a paper published yesterday in the magazine Science, IBM researchers announced the first integrated circuit fabricated from wafer-size graphene, and demonstrated a broadband frequency mixer operating at frequencies up to 10 gigahertz (10 billion cycles/second).

Designed for wireless communications, this graphene-based analog integrated circuit could improve today's wireless devices and points to the potential for a new set of applications. At today's conventional frequencies, cell phone and transceiver signals could be improved, potentially allowing phones to work where they can't today while, at much higher frequencies, military and medical personnel could see concealed weapons or conduct medical imaging without the same radiation dangers of X-rays.
