Kusintha kuchokera ku silicon kupita ku semiconductors okhala ndi bandgap yayikulu (gallium nitride, silicon carbide ndi ena) kumatha kukulitsa ma frequency ogwiritsira ntchito ndikuwongolera magwiridwe antchito. Chifukwa chake, amodzi mwamagawo odalirika ogwiritsira ntchito tchipisi tambiri-gap ndi ma transistors ndi kulumikizana ndi ma radar. Zipangizo zamagetsi zochokera ku GaN zothetsera "kunja kwa buluu" zimapereka kuwonjezeka kwa mphamvu ndi kuwonjezereka kwa ma radar osiyanasiyana, omwe asilikali adagwiritsa ntchito nthawi yomweyo.
Kampani ya Lockheed Martin kuti zida zoyambira zam'manja za radar (ma radar) ozikidwa pamagetsi okhala ndi zinthu za gallium nitride zidaperekedwa kwa asitikali aku US. Kampaniyo sinabwere ndi chilichonse chatsopano. Ma radar a batri a AN/TPQ-2010, omwe adatengedwa kuyambira 53, adasamutsidwa ku gawo la gawo la GaN. Iyi ndi radar yoyamba komanso mpaka pano yokhayo padziko lonse lapansi.
Pogwiritsa ntchito zida za GaN zomwe zimagwira ntchito, radar ya AN/TPQ-53 idakulitsa kuchuluka kwa zida zankhondo zotsekedwa ndipo idakwanitsa kutsata zolinga zamlengalenga nthawi imodzi. Makamaka, radar ya AN/TPQ-53 idayamba kugwiritsidwa ntchito motsutsana ndi ma drones, kuphatikiza magalimoto ang'onoang'ono. Kuzindikiritsa malo omenyera zida zankhondo kutha kuchitidwa mu gawo la 90-degree komanso ndikuwona ma degree 360 ββmozungulira.
Lockheed Martin ndiye yekhayo amene amapereka ma radar okhazikika (gawo limodzi) kwa asitikali aku US. Kusintha kwa zinthu za GaN kumapangitsa kuti izidalira utsogoleri wanthawi yayitali pakuchita bwino komanso kupanga ma radar.
