Raytheon Demonstrates Gallium Nitride Advantages in Radar Components

TEWKSBURY, Mass., April 16, 2008 PRNewswire — Raytheon Company (NYSE: RTN) is developing transmit-receive modules based on the advanced semiconductor gallium nitride (GaN) for use in future radar upgrades.

"This transmit-receive module demonstration and parallel reliability testing show that GaN will soon be ready to take over where increased power and advanced capabilities are needed," said Mark Russell, vice president of Engineering at Raytheon Integrated Defense Systems (IDS).

The development is part of an on-going 42-month, $11.5 million Next Generation Transmit Receive Integrated Microwave Module (NGT) contract funded by the Missile Defense Agency's Advanced Technology Directorate. Raytheon is demonstrating that transmit-receive modules using GaN-powered monolithic microwave integrated circuit amplifiers have a significant performance advantage in that they provide significantly higher radio frequency power with greater efficiency than current modules.

The NGT program leverages GaN technology being developed under the Defense Advanced Research Projects Agency's Wide Bandgap Semiconductor program as well as company-funded efforts.

Russell said that GaN technology significantly extends the warfighter's reach into the battlespace by increasing radar ranges, sensitivity and search capabilities. Alternatively, the technology enables reduction in the size of the antenna, which improves transportability and reduces acquisition and lifecycle costs without sacrificing performance.

"The NGT program is important because it is the first significant government-funded contract to address the use of the more capable GaN semiconductors in a relevant environment," said Steve Bernstein, IDS' program manager on NGT. "This recent demonstration shows that GaN technology performs better in transmit-receive modules representative of those used in modern radars."

Integrated Defense Systems is Raytheon's leader in Joint Battlespace Integration providing affordable, integrated solutions to a broad international and domestic customer base, including the U.S. Missile Defense Agency, the U.S. Armed Forces and the Department of Homeland Security.

Raytheon Company, with 2007 sales of $21.3 billion, is a technology leader specializing in defense, homeland security and other government markets throughout the world. With a history of innovation spanning 86 years, Raytheon provides state-of-the-art electronics, mission systems integration and other capabilities in the areas of sensing; effects; and command, control, communications and intelligence systems, as well as a broad range of mission support services. With headquarters in Waltham, Mass., Raytheon employs 72,000 people worldwide.
