REDONDO BEACH, Calif., June 3, 2014 /PRNewswire/ -- A pioneer in the design and fabrication of advanced semiconductors, Northrop Grumman Corporation (NYSE: NOC) has introduced two new high power gallium nitride (GaN) monolithic microwave integrated circuit (MMIC) power amplifiers for Ka-band satellite communication terminals and point-to-point digital communication links.
The APN228 and APN229 power amplifiers were developed with the company's proprietary GaN high-electron mobility transistor (HEMT) power process and provide unmatched saturated output power of 13 and 8 watts, respectively. These second-generation power amplifiers offer the highest power density of any existing Ka-band GaN product on the market.
The broadband, two-stage amplifiers operate from 27 to 31 GHz, and, when integrated in high efficiency solid-state power amplifiers (SSPAs), allow for higher data rate in communication systems.
"GaN-based SSPAs are a far more desirable solution to costly traveling-wave tubes which require more complex, higher voltage power supplies and a lengthier production time," said Frank Kropschot, general manager, Microelectronics Products and Services, Northrop Grumman Aerospace Systems.
"APN228 and APN229 will allow our customers to reduce the cost and complexity of power-combining, and offer a significant cost advantage compared to the current generation of Ka-band products," he added.
Samples of these MMIC power amplifiers will be available by mid-July, and packaged versions will be available for sampling later this year. Information and data sheets on the Ka-band and other GaN power amplifiers are available online at: www.northropgrumman.com/mps
Northrop Grumman manufactures the power amplifiers at its state-of-the-art microelectronics wafer fabrication facility in Manhattan Beach. A Department of Defense Trusted Foundry, the facility uses advanced gallium nitride, gallium arsenide and indium phosphide semiconductor manufacturing processes.
Northrop Grumman is a leading global security company providing innovative systems, products and solutions in unmanned systems, cyber, C4ISR, and logistics and modernization to government and commercial customers worldwide. Please visit www.northropgrumman.com for more information.
