Guinness World Records(tm) has notified the company that its ultra-fast,
one-terahertz transistor set a new world record for transistor speed. The
device, announced in 2007, provides much higher frequency and bandwidth
capabilities.

"Guinness World Records(tm) is synonymous with accomplishment, inspiration and
success," said Tom Romesser, chief technology officer for Northrop Grumman
Aerospace Systems. "We have many record-breaking 'firsts' in Microelectronics
and the recognition by Guinness is extremely gratifying."

The company produced and demonstrated an indium phosphide-based high electron
mobility transistor (InP HEMT) with a maximum operating frequency of more than
1,000 gigahertz, or greater than one terahertz. Researchers led by Aerospace
Systems' Richard Lai detailed how they developed the terahertz-speed transistor
in a technical paper delivered at the International Electron Devices Meeting in
Washington, D.C., sponsored by the Electron Devices Society of the Institute of
Electrical & Electronic Engineers.

The terahertz transistor is the latest generation in a long line of compound
semiconductor products that Northrop Grumman has produced by the millions for
government and commercial uses. Tests conducted by NASA's Jet Propulsion
Laboratory in Pasadena, Calif., validated the ultra-fast transistor by measuring
a three-stage millimeter wave integrated circuit amplifier at 340 gigahertz with
greater than 15-decibel gain. Recent tests conducted at Northrop Grumman
confirmed an even more impressive 18-decibel gain at 340 gigahertz.

Development of the terahertz-speed InP HEMT was supported by the Defense
Advanced Research Projects Agency, the U.S. Army Research Laboratory and
internal company funds. Northrop Grumman has more than 30 years of experience
developing advanced semiconductor technologies for space applications.

Northrop Grumman Corporation is a leading global security company whose 120,000
employees provide innovative systems, products and solutions in aerospace,
electronics, information systems, shipbuilding and technical services to
government and commercial customers worldwide.
