Russian manufacturers are seeking avenues to address requirements for airborne radar systems.
Airborne radar capabilities have become a progressively larger factor in the competition for fighter aircraft export sales, as most advanced air forces now require a fighter that includes an active electronically scanned array (AESA) radar set.
The AESA radar in the latest model of Saab’s JAS-39 Gripen E/F models, for example, will feature an antenna array fitted with gallium nitride (GaN)-based transmit/receive (T/R) modules. GaN technology is the next step in the evolution of AESA, offering higher efficiency and generating less heat than the gallium arsenide (GaAs) modules used in most other competitors’ models of AESA.
