Udinga ukusebenzisa umzila we-impedance olawulwayo kanye nokulandelana okufushane nokuqondile. Beka izindiza zomhlaba eduze kwezingqimba zesignali. Lokhu kusetha kunciphisa ukulahleka kwesignali futhi kugcina idatha yakho icacile.
Kungani ama-PCB e-5G edinga izendlalelo eziningi kangaka?
Udinga izendlalelo ezengeziwe ukuze uvumelane nazo zonke izindlela zesignali ezisheshayo, izindiza zamandla, kanye nezindiza zomhlaba. Izendlalelo ezengeziwe zikusiza ukuthi uhlukanise amasignali futhi unciphise ukuphazamiseka.
Yiziphi izivivinyo okufanele uzisebenzise ngaphambi kokusebenzisa i-5G PCB?
Kufanele wenze izivivinyo ze-RF, ukujikeleza kwezinga lokushisa, kanye nokuhlolwa komswakama. Sebenzisa i-Vector Network Analyzer ukukala ukulahleka kwesiginali. Lezi zivivinyo zibonisa ukuthi i-PCB yakho isebenza kahle yini ezimweni zangempela.
