Jungtin\u0117se Valstijose pradedamas naujas bandym\u0173 etapas, kuriame mikroprocesori\u0173 ir radijo da\u017eni\u0173 (RF) moduli\u0173 au\u0161inimui naudojami mikroskopiniai deimantai. \u201eNorthrop Grumman\u201c prane\u0161\u0117 gavusi kontrakt\u0105 pagal DARPA program\u0105 THREADS, kurios tikslas \u2013 \u012f naujos kartos puslaidininkius integruoti deimantu paremt\u0105 \u0161ilumos sklaid\u0105.<\/p>\n
Pagrindin\u0117 problema, kuri\u0105 siekiama spr\u0119sti, yra \u0161iluma: did\u0117jant galios tankiui, lustai vis da\u017eniau atsiremia \u012f temperat\u016brines ribas, kurios ma\u017eina patikimum\u0105 ir riboja spart\u0105. Deimantas \u010dia vertinamas d\u0117l i\u0161skirtinio \u0161ilumos laidumo, kuris, lyginant su variu, yra kelis kartus didesnis, tod\u0117l jis gali grei\u010diau i\u0161vesti \u0161ilum\u0105 i\u0161 kar\u0161\u010diausi\u0173 grandini\u0173 viet\u0173.<\/p>\n
Pasak bendrov\u0117s, pirmojoje THREADS faz\u0117je pavyko padidinti tam tikr\u0173 sprendim\u0173 galios lyg\u012f ma\u017edaug 3,3 karto, lyginant su \u012fprastais analogais. Antroji faz\u0117 orientuota \u012f dar didesn\u012f \u0161uol\u012f, ypa\u010d ten, kur svarb\u016bs kompakti\u0161ki, bet labai galingi RF si\u0173stuvai, naudojami ry\u0161iui, radarams ir palydovin\u0117ms sistemoms.<\/p>\n
Technologijos esm\u0117 \u2013 deimanto strukt\u016br\u0173 \u012fvedimas tiesiai \u012f lust\u0105, kad \u0161iluma b\u016bt\u0173 pa\u0161alinama i\u0161 RF grandini\u0173 kuo ar\u010diau jos susidarymo vietos. \u201eNorthrop Grumman\u201c nurodo neseniai s\u0117kmingai atlikusi didel\u0117s galios bandymus, kuriuose deimantas pad\u0117jo suma\u017einti \u012frengini\u0173 temperat\u016br\u0105, padidinti j\u0173 greit\u012f ir patikimum\u0105 bei leido dirbti su auk\u0161tesniais galios lygiais neprarandant pralaidumo.<\/p>\n
\u201eTemperat\u016bra jau seniai riboja mikroelektronikos galimybes, net ir galio nitrido, kuris \u0161iandien yra standartas. Deimanto integravimas tiesiai \u012f lustus veikia kaip sustiprinta au\u0161inimo sistema ir leid\u017eia didinti gali\u0105 be perdegimo rizikos\u201c, \u2013 sak\u0117 \u201eNorthrop Grumman\u201c mikroelektronikos vadovas Benas Heyingas.<\/p>\n
Tokie sprendimai atitinka platesn\u0119 gynybos elektronikos krypt\u012f: siekiama didesn\u0117s galios ma\u017eesniame t\u016bryje, kartu didinant patikimum\u0105 ir ma\u017einant energijos nuostolius. Jei antrosios faz\u0117s tikslai bus pasiekti, deimantu au\u0161inami RF lustai gal\u0117t\u0173 tapti vienu i\u0161 praktini\u0173 b\u016bd\u0173 per\u017eengti \u0161iandienines termines ribas ir pagreitinti naujos kartos ry\u0161io bei radar\u0173 \u012frangos diegim\u0105.<\/p>\n","protected":false},"excerpt":{"rendered":"
