01 ukuthuthuka okuphelele kwe-5G ERA: Izidingo ezintsha zeziteshi ze-5G Base iziteshi!
Izikhungo ze-5G Base ziqukethe iBBU (i-Baseband Unit) ne-RRU (iyunithi yomsakazo elikude). I-RRU ivaliwe ngokuvama e-antenna, nge-fiber optical exhuma i-BBU ne-RRU, nezintambo ze-coaxial ezixhuma i-RRU ne-antenna ngokudluliswa kwemininingwane. Uma kuqhathaniswa ne-3G ne-4G, i-BBU ne-RRU ngesidingo 5g ukubhekana namavolumu wedatha ephakeme, imvamisa yenkampani ephakeme eholela ekuhlinzekeni okungazinzile kwamanje kuma-chip asebenzayo kuya kuma-chip asebenzayo. Lokhu kudinga ama-capacitors aphansi aphansi okumelana (ESR) wokuhlunga, ukuqeda umsindo, kanye nokuqinisekisa ukugeleza kwamanje.
Ama-capacitors ahlanganiswe ama-9 ymin nama-tapalum capacitors adlala izindima ezibalulekile

Eziteshini eziyisisekelo ze-5G, ama-capacitors e-ymin embonisiwe kanye nama-polymer tantalum capacitors ayizinto ezibalulekile, enikeza imisebenzi yokuhlunga enhle kakhulu futhi aqinisekise ukuthembeka kwesiginali. Ama-capacitors ahlanganisiwe ane-ESR ye-Ultra-Low ESR ye-3Mω, ekopela ngempumelelo umsindo ovela emigqeni yamandla ukuze uqinisekise ukuqina futhi uthuthukise ikhwalithi nokuqina kwesiginali. Ngaleso sikhathi, ama-capacitors e-polymer tantalum, ngenxa yokusebenza kwawo okushisa okuphezulu nokuqina kwesikhathi eside, alungele ukusetshenziswa ezindaweni ezishisa kakhulu zeziteshi ze-5G base, exhasa ukuhanjiswa kwesiginali ephezulu kanye nokusebenza kahle. Ukusetshenziswa kwalawa ma-capacitor asebenza kakhulu kubalulekile ekufezekiseni ijubane eliphezulu, amakhono aphezulu obuchwepheshe be-5G.
A. I-ESR ephansi (ukumelana okulinganayo kochungechunge):Ama-capacitors ahlanganisiwe kanye nama-capacitors aphethe ama-polymer tantalum ane-ESR ephansi kakhulu, ikakhulukazi ama-capacitors ahlanganisiwe afinyelela i-ESR ephansi ye-ultra-low ye-3MY. Lokhu kusho ukuthi banganciphisa ukulahleka kwamandla ezicelo zemvamisa ephezulu, bathuthukise ukusebenza kwamandla, futhi baqinisekise ukusebenza okusebenzayo kweziteshi eziyisisekelo ze-5G.
B. Ukubekezelela okuphezulu okuphezulu:Ama-capacitors ahlanganisiwe kanye nama-capacitors we-polymer tantalum angamelana nezindlela ezinkulu ze-ripple, ezilungele ukuphatha ukuguquguquka kwamanje eziteshini ezingama-5G, ukuhlinzeka ngokuphuma kwamandla okuzinzile kanye nokuqinisekisa ukusebenza okuthembekile ngaphansi kwezimo ezihlukile zomthwalo.
C. Ukuqina okuphezulu:Ama-capacitors ahlanganisiwe kanye nama-capacitors aphethe ama-polymer tantalum akhombisa ukuqina okuphezulu, egcina ukusebenza kwawo kagesi ngezikhathi ezengeziwe. Lokhu kubaluleke kakhulu eziteshini eziyisisekelo ze-5G ezidinga ukusebenza kwesikhathi eside, ukuqinisekisa ukuthembeka kwemishini nokuphila isikhathi eside.
03 Isiphetho
Ama-capacitors we-ymin stocmer swood-state-smote capacitors kanye nama-polymer tantalum capacitors anezici ezifana ne-Ultra-Low ESR, ukubekezelela okuphezulu okuphezulu, nokuqina okuphezulu. Babhekana ngempumelelo namaphoyinti obuhlungu bokuphakelwa kwamandla okungazinzile kuma-chip asebenzayo eziteshini eziyisisekelo ze-5G, ukuqinisekisa ukuthi isikhathi eside sokwethezeka kanye nokwethenjwa noma ngaphansi kokushintshashintsha kwezinga lokushisa kwangaphandle. Banikeza isiqinisekiso esinamandla sokuthuthuka kanye nokusungulwa kweziteshi ze-5G Base.
