Northrop Grumman Sets T/R Module Standard

Northrop Grumman said it has set a new standard for its gallium nitride-based high-power transmit/receive (T/R) modules, reliably operating them for more than 180 days during continuous high-power testing.

The tests prove that the next generation of active electronically scanned arrays (AESA) is capable of reliable operation while producing much greater radar sensitivity, at higher efficiency and lower cost, Northrop Grumman said April 12.

In an evaluation conducted by the company's Advanced Concepts and Technology Division, the T/R modules were tested by using high-stressing operational long-pulse waveforms, which operated on the modules nonstop for more than six months. The waveforms were designed to simulate the electronic activities of actual radar functions, in a relevant environment.

“By successfully employing the latest advances in high-power semiconductor technology in a functioning T/R module, we have demonstrated the great performance and reliability of our design approach,” stated Steve McCoy, vice president of the Advanced Concepts business unit.

“This new level of maturity also supports technology readiness for the next generation of Northrop Grumman's high performance, low cost AESA radars, and opportunities for cost reduction and performance upgrades to our current AESA product line.”
