Sidee PCB-yada Anteenada ee Wajiga ah u Xoojiyaan Nidaamyada Difaaca Hawada ee Jiilka Xiga

Iyadoo dagaalyahannada qarsoon ee jiilka shanaad iyo gantaalada hypersonic ay soo baxayaan iyagoo ah khataro muhiim ah, raadaarada dhaqameed ee si farsamo ahaan loo baaray ayaa ku dhibtoonaya inay la qabsadaan xaaladaha dagaalka ee si degdeg ah u kobcaya. Raadaarka safka hore, oo leh isteerinka iftiinka aan firfircooneyn iyo awoodaha raadraaca bartilmaameedka badan leh, ayaa noqday laf-dhabarta nidaamyada difaaca hawada ee jiilka soo socda. Xudunta horumarkan tignoolajiyadeed waxaa ku jira PCB-ga anteenada safka hore - geesiga aan la xusin ee ka dambeeya nidaamyada raadaarka ee horumarsan.

1. Waa maxay PCB-ga Anteenada Wajiga ah ee la Wajiyey?

PCB-ga anteenada wejiga ah waa guddi wareeg oo soo noqnoqota oo loogu talagalay in lagu xakameeyo isteerinka firfircoon ee nidaamyada radar-ka.

Yaraynta iyo shaqada la xoojiyay waxaa lagu gaaraa microvias iyo tignoolajiyada is dulsaarka, iyadoo la isku darayo kumanaan modules oo gudbin/hel (T/R) ah oo ku jira meel xaddidan. Tani waxay u suurtogelinaysaa kala fogaanshaha walxaha anteenada inay u adkaato sida ≤0.5λ, taasoo si weyn u hagaajinaysa saxnaanta isteerinka iftiinka. Qaybaha ku jira sida capacitors-ka iyo iska caabbinta ee ku jira lakabka PCB waxay yareeyaan dhererka wadada calaamadda, iyagoo yareynaya daahitaanka iyo buuqa.

Kalsoonida Deegaannada Ba'an:

Xalalka maaraynta kulaylka, oo ay ku jiraan walxaha birta ku salaysan (tusaale ahaan, PCB-yada ku salaysan aluminium) iyo vias-yada kulaylka gudbiya, waxay hubiyaan hawlgal deggan oo ah qalabka xoojiya awoodda GaN heerkul ilaa 150°C. Iska caabbinta gariirka iyo ilaalinta daxalka, oo shahaado haysta heerarka IPC-6012 Class 3, waxay u oggolaanayaan hawlgal xaaladaha adag sida heerkulka aadka u daran, buufinta milixda, iyo shoogga farsamada.
