بحسب ديفنس نيوز , تقوم ساب السويدية بالتحضير لتركيب رادارات مصنوعة من موديولات الجاليوم نايتريد (GaN ) الاكثر قوة وكفاءة من المستخدمة حاليا في رادارات الايسا وهي الجاليوم ارسينايد ( GaaS ) .
بسبب كلفته العالية , كان هذا عائق امام التوسع في انتاج رادارات بموديولات الجاليوم نايتريد ولكن النتائج المشجعة لادائها شجّعت المضي قدما في تبني هذه المادة في الرادارات القادمة اضافة لاجهزة التشويش ( Jammers ) وانظمة التحذير السلبية ( Passive Warning Systems ) .
الجاليوم نايتريد بحسب المصدر , يرفع من الكفاءة بنسبة 25% من الجيل الحالي ويمكنها ان توفر تغطية 360 درجة ..

Gallium Nitride (GaN), probably the most important semiconductor material since silicon, will be used by Saab on the Gripen E aircraft, reports Defense News.
Gallium Nitride has long been seen as a powerful alternative to gallium arsenide which is currently popular for making modules for AESA radars.
The cost of Gallium Nitride has been a deterrent in its use in ground radars. However, with the demonstration of successful prototyping of Active Electronically Scanned Array (AESA) and Gallium Nitride (GaN) technologies by US firms like Raytheon, things are changing.
“The substance will be used in jammers and passive warning systems, boosting efficiency by 25 percent,” said Ulf Nilsson, the head of the Gripen program.
In addition to enabling future 360 sensor coverage, GaN technologies will also increase the defended area and decrease the time to detect, discriminate and engage threats.
According to Lennart Sindahl, Saab’s deputy CEO, Saab is now ahead of the curve on GaN.
“Our worst competitor said ‘you are now six years ahead of us,’” Sindahl said.
