Indima Ebalulekileyo Yezinto Eziphambili ZeCeramic Kwizinto Ezilandelayo Ze-RF/Microwave

Ukusebenza kunye nokuthembeka kwezinto zanamhlanje ze-RF kunye ne-microwave, ezifana nezihluzi, ii-diplexers, kunye nee-amplifiers, zixhaswa kakhulu zizinto zazo zokupakisha. Uhlalutyo lwakutshanje lweshishini lubonelela ngothelekiso olucacileyo lwezinto ezintathu eziphambili ze-ceramic substrate—i-Alumina (Al₂O₃), i-Aluminium Nitride (AlN), kunye ne-Silicon Nitride (Si₃N₄)—nganye ikhonza amacandelo ahlukeneyo emarike ngokusekelwe kumlinganiselo wokusebenza kunye neendleko.

Ukwahlulwahlulwa kwezinto kunye nezicelo eziphambili:

I-Alumina (Al₂O₃):Isisombululo esisetyenzisiweyo nesingabizi kakhulu. Ngombane ohamba ngobushushu obuyi-25-30 W/(m·K), ilawula usetyenziso oluxabisa kakhulu njengezixhobo ze-elektroniki zabathengi kunye nezibane ze-LED eziqhelekileyo, ezibamba ngaphezulu kwe-50% yemarike.

I-Aluminium Nitride (AlN):Ukhetho olukhethwayo lweiimeko eziphindaphindayo nezinamandla aphezulu. Ukuqhuba kwayo okugqwesileyo kobushushu (200-270 W/(m·K)) kunye nokulahleka kwayo okuphantsi kwe-dielectric kubalulekile ekupheliseni ubushushu nasekugcineni ukuthembeka kwesignali kuIzikhulisi zamandla zesikhululo sesiseko se-5Gkunye neenkqubo zeradar eziphambili.

I-Silicon Nitride (Si₃N₄):Intshatsheli ethembekileyo kakhulu. Inika amandla oomatshini angcono kunye nokumelana okugqwesileyo kobushushu, ibaluleke kakhulu kwimisebenzi ebalulekileyo phantsi koxinzelelo olukhulu, njengakwii-aerospace kunye neemodyuli zamandla ezithuthi zombane zesizukulwana esilandelayo.

E-Ingcamango yeMicrowave,Siyiqonda nzulu le siseko sesayensi yezinto eziphathekayo. Ubuchule bethu ekuyileni nasekuveliseni izinto ze-microwave ezisebenza kakuhle, kuquka izihluzi ze-cavity, ii-diplexers, kunye neendibano ezenziwe ngokwezifiso, zakhelwe ekukhetheni izixhobo ezifanelekileyo ezifana ne-AlN okanye i-Si₃N₄ substrates. Oku kuqinisekisa ukuba iimveliso zethu zibonelela ngolawulo lobushushu olufunekayo, ubumsulwa besignali, kunye nokuthembeka kwexesha elide okufunekayo kwiinkqubo ezifuna ubuchwephesha kunxibelelwano, kwisathelayithi nakwiinkqubo zokhuselo.
