I-5G, ubuchwepheshe bezokuxhumana beselula yesizukulwane sesihlanu isizukulwane esisha sobuchwepheshe bezokuxhumana beselula obunezimpawu zesivinini esikhulu, ukubambezeleka okuphansi nokuxhumana okukhulu.Kuyingqalasizinda yenethiwekhi ukubona ukuxhumana komshini womuntu nento.
I-inthanethi yezinto ingumzuzi omkhulu we-5G.Amandla amakhulu okushayela kwe-5G akusona nje isidingo esikhulayo sabathengi samanethiwekhi asheshayo, kodwa futhi ukwanda kwamadivayisi okuxhumana endaweni yezimboni.Lezi zimboni zithembela kakhulu kumadivayisi enethiwekhi ukuze aqoqe futhi ahlaziye idatha, enze izinqubo zebhizinisi zisebenze kahle, zithuthukise ukukhiqiza, futhi zithuthukise imikhiqizo namasevisi ngokuqhubekayo.I-5G kulindeleke ukuthi isize amabhizinisi alawule ngempumelelo inani elikhulayo lolwazi olukhiqizwa I-inthanethi yezinto, futhi ithuthukise imilayezo esheshayo eseduze edingekayo kumasevisi abalulekile afana nokuhlinzwa okusizwa yirobhothi noma ukushayela ukuzimela.
I-Circulator ne-isolator ingenye yamadivayisi ayisisekelo eziteshi eziyisisekelo ze-5G.Lonke uhlelo lokuxhumana ngomakhalekhukhwini ngokuvamile lwakhiwe ingqalasizinda yokuxhumana ngomakhalekhukhwini, uhlelo lokuxhumana ngomakhalekhukhwini kanye nemikhiqizo yesiphetho sokuxhumana ngomakhalekhukhwini.Isiteshi sesisekelo singesemishini eyisisekelo yokuxhumana ngomakhalekhukhwini.Uhlelo lwesiteshi sesisekelo luvame ukwakhiwa i-RF front-end, i-base station transceiver nesilawuli sesiteshi esiyisisekelo.I-RF front-end inesibopho sokuhlunga isignali nokuhlukaniswa, i-base station transceiver inesibopho sokwamukela isignali, ukuthumela, ukukhulisa nokunciphisa, futhi isilawuli sesiteshi esiyisisekelo sinesibopho sokuhlaziya isignali, ukucubungula kanye nokulawula isiteshi sesisekelo.Kunethiwekhi yokufinyelela okungenantambo, i-circulator isetshenziswa kakhulukazi ukuhlukanisa isignali yokuphumayo nesignali yokufaka ye-base station antenna.Ngezinhlelo zokusebenza ezithile, umjikelezi angafinyelela imisebenzi elandelayo namanye amadivaysi:
1. Ingasetshenziswa njenge-antenna commoner;
2. Ngokuhambisana ne-BPF ne-attenuation esheshayo, isetshenziswa kumjikelezo wokuhlukanisa amagagasi;
3. Itheminali yokumelana netheminali ixhunywe ngaphandle kwesiyingi njengesihlukanisi, okungukuthi, isignali iwukufaka kanye nokuphumayo kusuka kumbobo ebekiwe;
4. Xhuma i-ATT yangaphandle futhi uyisebenzise njengesiyingi esinomsebenzi wokubona amandla.
Njengenye yezingxenye ezibaluleke kakhulu, izingcezu ezimbili zeI-Samarium Cobalt disc magneticnikeza inkambu kazibuthe edingekayo ukuze kucheme ukuhlangana okulayishwe i-ferrite.Ngenxa yezici zokumelana nokugqwala okuhle kakhulu nokuzinza kokusebenza okuphezulu kuya kuma-degree angama-350 ℃, womabili omagnethi be-SmCo5 kanye ne-Sm2Co17 asetshenziswa kuma-circulator noma izihlukanisi.
Ngokusetshenziswa kobuchwepheshe be-MIMO obukhulu be-5G, ukusetshenziswa kwama-circulator nama-isolator kuye kwanda kakhulu, futhi indawo yemakethe izofinyelela izikhathi eziningana ze-4G.Esikhathini se-5G, imfuneko yomthamo wenethiwekhi iphakeme kakhulu kunaleyo ye-4G.I-MIMO Enkulu (I-Multiple-Input Multiple-Output) ingobunye bobuchwepheshe obubalulekile bokuthuthukisa umthamo wenethiwekhi.Ukuze kusekelwe lobu buchwepheshe, inani leziteshi ze-antenna ze-5G lizokhula kakhulu, futhi inani leziteshi ze-antenna zomkhakha owodwa lizokhula kusuka eziteshini ze-4 neziteshi ze-8 esikhathini se-4G kuya eziteshini ze-64.Ukuphindwa kabili kwenani lamashaneli nakho kuzoholela ekwenyukeni okukhulu kwesidingo sama-circulator ahambisanayo nezihlukanisi.Ngesikhathi esifanayo, ngezidingo ze-lightweight kanye ne-miniaturization, izidingo ezintsha zevolumu nesisindo zibekwe phambili.Ukwengeza, ngenxa yokuthuthukiswa kwebhendi ye-frequency yokusebenza, ukungena kwesignali kumpofu futhi ukuncishiswa kukhulu, futhi ukuminyana kwesiteshi se-5G kuzoba phezulu kune-4G.Ngakho-ke, esikhathini se-5G, ukusetshenziswa kwama-circulator kanye nama-isolator, bese kuthi ama-magnets e-Samarium Cobalt azokhula kakhulu.
Okwamanje abakhiqizi abakhulu be-circulator / isolator emhlabeni bahlanganisa i-Skyworks e-USA, i-SDP e-Canada, i-TDK e-Japan, i-HTD e-China, njll.
