01 Intuthuko Ephelele Esikhathini Se-5G: Izidingo Ezintsha Zeziteshi Eziyisisekelo Ze-5G!
Iziteshi zesisekelo ze-5G zakhiwa yi-BBU (Baseband Unit) kanye ne-RRU (Remote Radio Unit). I-RRU ivame ukubekwa eduze kwe-antenna, nge-optical fiber exhumanisa i-BBU kanye ne-RRU, kanye nezintambo ze-coaxial ezixhumanisa i-RRU kanye ne-antenna ukuze kudluliselwe ulwazi. Uma kuqhathaniswa ne-3G kanye ne-4G, i-BBU kanye ne-RRU ku-5G zidinga ukusingatha amanani edatha akhuphukile kakhulu, kanye namaza aphezulu okuthwala aholela ekuhlinzekweni okungazinzile komthombo wamandla oqondile kuma-chip asebenzayo. Lokhu kudinga ama-capacitor aphansi e-Equivalent Series Resistance (ESR) ukuze kuhlungwe, kuqedwe umsindo, futhi kuqinisekiswe ukugeleza komthombo wamandla okushelelayo.
02 Ama-Capacitor e-YMIN Stacked kanye nama-Capacitor e-Tantalum adlala indima ebalulekile

Eziteshini zesisekelo ze-5G, ama-capacitor e-YMIN ahlanganisiwe kanye nama-capacitor e-polymer tantalum aqhutshwayo ayizingxenye ezibalulekile, ahlinzeka ngemisebenzi emihle kakhulu yokuhlunga nokuqinisekisa ubuqotho besignali. Ama-capacitor ahlanganisiwe ane-ESR ephansi kakhulu ye-3mΩ, ehlunga ngempumelelo umsindo ovela ezintanjeni zikagesi ukuqinisekisa ukuqina nokuthuthukisa ikhwalithi nokuqina kwesignali. Okwamanje, ama-capacitor e-polymer tantalum aqhutshwayo, ngenxa yokusebenza kwawo okuvelele kokushisa okuphezulu kanye nokuqina kwesikhathi eside, afaneleka kakhulu ukusetshenziswa ezindaweni zokushisa okuphezulu zeziteshi zesisekelo ze-5G, esekela ukudluliselwa kwesignali ngesivinini esikhulu nokuqinisekisa ukuthembeka nokusebenza kahle kokuxhumana. Ukusetshenziswa kwala ma-capacitor asebenza kahle kubalulekile ekufinyeleleni amakhono aphezulu obuchwepheshe be-5G asheshayo, aphezulu.
A. I-ESR Ephansi (Ukumelana Nochungechunge Olulinganayo):Ama-capacitor ahlanganisiwe kanye nama-capacitor e-polymer aqhubayo ane-ESR ephansi kakhulu, ikakhulukazi ama-capacitor ahlanganisiwe afinyelela i-ESR ephansi kakhulu engu-3mΩ. Lokhu kusho ukuthi anganciphisa ukulahlekelwa kwamandla ekusetshenzisweni kwemvamisa ephezulu, athuthukise ukusebenza kahle kwamandla, futhi aqinisekise ukusebenza kahle kweziteshi zesisekelo ze-5G.
B. Ukubekezelelana Kwamanje Okukhulu Kokugobhoza:Ama-capacitor ahlanganisiwe kanye nama-capacitor e-polymer tantalum aqhubayo angamelana nemisinga emikhulu ye-ripple, afanelekela ukusingatha ukuguquguquka kwamanje eziteshini zesisekelo ze-5G, ahlinzeka ngokukhipha amandla okuzinzile nokuqinisekisa ukusebenza okuthembekile ngaphansi kwezimo ezahlukene zomthwalo.
C. Ukuqina Okuphezulu:Ama-capacitor ahlanganisiwe kanye nama-capacitor e-polymer tantalum abonisa ukuzinza okuphezulu, agcina ukusebenza kwawo kagesi isikhathi eside. Lokhu kubaluleke kakhulu eziteshini zesisekelo ze-5G ezidinga ukusebenza okuzinzile isikhathi eside, okuqinisekisa ukuthembeka kwemishini kanye nobude bayo.
03 Isiphetho
Ama-capacitor e-polymer ahlanganisiwe e-YMIN kanye nama-capacitor e-polymer aqhubayo anezici ezifana ne-ESR ephansi kakhulu, ukubekezelelana kwamanje kwe-ripple ephezulu, kanye nokuzinza okuphezulu. Abhekana ngempumelelo nezindawo ezibuhlungu zokunikezwa kwamandla okungazinzile kuma-chip asebenzayo eziteshini zesisekelo ze-5G, aqinisekisa ukuthi umkhiqizo uhlala isikhathi eside futhi uthembekile ngisho nangaphansi kokushintshashintsha kwezinga lokushisa langaphandle. Anikeza isiqinisekiso esiqinile sokuthuthukiswa nokusungulwa kweziteshi zesisekelo ze-5G.
