Made in IBM Labs: IBM Scientists Unveil Highly Integrated Millimeter-Wave Transceiver for Mobile Communications and Radar Imaging applications

Researchers invent solution that seamlessly brings together 4 integrated chips and 64 antennas in a single package for mobile and transportation solutions
Proven SiGe BiCMOS prototype takes advantage of under-utilized short-wavelength frequency

SEATTLE, WA – 04 Jun 2013: Scientists from IBM have achieved a milestone in creating a phased-array transceiver that contains all of the millimeter-wave components necessary for both high data-rate communications and advanced-resolution radar imaging applications.  The newly demonstrated integrated circuits (ICs) tackle data bottleneck issues for mobile communications applications and allow radar-imaging technology to be scaled down to the size of a computer laptop.

Advanced radio frequency integration has been a key driver in the explosive growth of mobile device capability and sophistication.  Millimeter-wave bandwidth has the ability to support Gb/s wireless communications, dramatically expanding opportunities for mobile backhaul, small cell infrastructure, and data center overlay network deployment.

NASA Releases Radar Movie of Asteroid 2012 DA14

An initial sequence of radar images of asteroid 2012 DA14 was obtained on the night of Feb. 15/16, 2013, by NASA scientists using the 230-foot (70-meter) Deep Space Network antenna at Goldstone, Calif. Each of the 72 frames required 320 seconds of data collection by the Goldstone radar.

The observations were made as the asteroid was moving away from Earth. The asteroid’s distance from the radar dish increased from 74,000 miles (120,000 kilometers) to 195,000 miles (314,000 kilometers). The resolution is 13 feet (four meters) per pixel. The images span close to eight hours and clearly show an elongated object undergoing roughly one full rotation. The images suggest that the asteroid has a long axis of about 130 feet (40 meters). The radar observations were led by scientists Lance Benner and Marina Brozovic of NASA’s Jet Propulsion Laboratory, Pasadena, Calif. Additional Goldstone radar observations are scheduled on February 18, 19 and 20. (more…)
