Siirdumine, mis h\u00f5lmab laia keeluga pooljuhtide kasutamist (nitraat, r\u00e4ni karbiid ja muud), v\u00f5imaldab oluliselt t\u00f5sta t\u00f6\u00f6 sagedusi ja t\u00f5sta lahenduste efektiivsust. Seet\u00f5ttu on laia keeluga kiipide ja transistorite \u00fcheks perspektiivikaks rakendusalaks side ja radarid. GaN-lahendustel p\u00f5hinev elektroonika pakub \"jaotamata pinnalt\" v\u00f5imsuse suurenemist ja radarite ulatuse laiendamist, mille eest on kohe kinni haaranud s\u00f5jav\u00e4gi.<\/p>\n

\"Ameerika<\/p>\n

Lockheed Martin teatas<\/a><\/noindex>, et USA v\u00e4gedesse on tarnitud esimesed mobiilsed radariseadmed (RLS), mis p\u00f5hinevad galliumnitriidist elektronikal. Ettev\u00f5ttes ei ole midagi uut v\u00e4lja m\u00f5eldud. GaN-elementide baasile on viidud \u00fcle alates 2010. aastast relvastusse v\u00f5etud kontrabattari radarid AN\/TPQ-53. See on esimene ja seni ainus radar laiap\u00f6\u00f6rdpooljuhtide peal.<\/p>\n

Aktiivsete GaN-komponentide \u00fclemineku t\u00f5ttu on radar AN\/TPQ-53 suurendanud peidetud suurt\u00fckipositsioonide tuvastamise vahemaa ning saanud v\u00f5imaluse samaaegseks j\u00e4lgimiseks \u00f5hutegevuste \u00fcle. Konkreetsemalt, radar AN\/TPQ-53 on hakanud kasutama droonide vastu, sealhulgas v\u00e4ikeste seadmete vastu. Peidetud suurt\u00fckipositsioonide tuvastamine saab toimuda nii 90-kraadises sektoris kui ka 360-kraadise ringvaatena.<\/p>\n

Lockheed Martin on ainu\u00fcksi aktiivse FARe (faasitud antennigrupi) radarite tarnija USA v\u00e4gedes. \u00dcleminek GaN-elementide baasile v\u00f5imaldab tal loota pikale ja kestvale juhtpositsioonile radariseadmete arenduse ja tootmise vallas.<\/p>\n
