Phetoho ea ho tloha silicon ho ea ho li-semiconductors tse nang le bandgap e pharaletseng (gallium nitride, silicon carbide le tse ling) e ka eketsa maqhubu a ts'ebetso le ho ntlafatsa katleho ea tharollo. Ka hona, e 'ngoe ea libaka tse tšepisang bakeng sa ho sebelisa li-chips le li-transistors tse pharalletseng ke likhokahano le radar. Lisebelisoa tsa elektronike tse thehiloeng ho litharollo tsa GaN "ka ntle ho putsoa" li fana ka keketseho ea matla le katoloso ea mefuta e mengata ea li-radar, tseo sesole se ileng sa li sebelisa hang-hang.
Khamphani ea Lockheed Martin hore lisebelisoa tsa pele tsa radar (li-radar) tse thehiloeng ho lisebelisoa tsa elektronike tse nang le likarolo tsa gallium nitride li ile tsa isoa ho masole a US. Khampani ha ea ka ea hlahisa letho le lecha. Li-radar tsa li-counter-betri tsa AN/TPQ-2010, tse amohetsoeng ho tloha 53, li fetiselitsoe motheong oa likarolo tsa GaN. Ena ke radar ea pele le ho fihlela hajoale e le 'ngoe feela ea semiconductor e pharalletseng lefatšeng.
Ka ho fetohela ho likarolo tse sebetsang tsa GaN, radar ea AN/TPQ-53 e ile ea eketsa sebaka sa ho lemoha libaka tse koetsoeng tsa libetsa 'me ea fumana bokhoni ba ho latela sepheo sa moea ka nako e le ngoe. Ka ho khetheha, radar ea AN/TPQ-53 e ile ea qala ho sebelisoa khahlanong le li-drones, ho akarelletsa le likoloi tse nyenyane. Ho tsebahatsa libaka tsa lithunya tse koahetsoeng ho ka etsoa ka bobeli karolong ea 90-degree le ka pono ea 360-degree hohle.
Lockheed Martin ke eena feela mofani oa thepa ea li-radar tse sebetsang ka mekhahlelo (li-fased array) ho sesole sa US. Phetoho ho setsi sa likarolo tsa GaN se e lumella ho itšetleha ka boetapele ba nako e telele lefapheng la ntlafatso le tlhahiso ea lits'ebetso tsa radar.
