AN/TPY-2 radars set to transition to GaN
Raytheon will develop a transition to production process to incorporate Gallium Nitride (GaN) components into existing and future AN/TPY-2 radars under a contract modification awarded by the US Missile Defense Agency. The modification was announced on 30 September.
Currently fielded AN/TPY-2 radars use Gallium Arsenide (GaAs) based transmit/receive modules to emit high power radiation.
Transitioning from GaAs to GaN technology will address system obsolescence in the ballistic missile defence radar, while enhancing range, and increasing detection and discrimination performance.
The AN/TPY-2 is a transportable X-band radar designed to counter the ballistic missile threat.
Dave Gulla, vice president of integrated defense systems mission systems and sensors, Raytheon, said: ‘GaN components have significant, proven advantages when compared to the previous generation GaAs technology.
‘Through this effort, Raytheon will develop a clear modernisation upgrade path for the AN/TPY-2 radar, enabling the system to better defend people and critical assets against ballistic missile threats at home and abroad.’
