5G, ukadaulo wachisanu ndi chimodzi waukadaulo wolumikizirana ndi mafoni ndi m'badwo watsopano waukadaulo wolumikizana ndi mafoni a Broadband okhala ndi mawonekedwe othamanga kwambiri, kuchedwa kochepa komanso kulumikizana kwakukulu. Ndilo maziko a netiweki kuzindikira makina amunthu ndi kulumikizana kwa chinthu.
Intaneti ya zinthu ndiyomwe imapindula kwambiri ndi 5G. Mphamvu yayikulu ya 5G sikungowonjezera kuchuluka kwa ogula pamaneti othamanga, komanso kuchuluka kwa zida zolumikizirana m'mafakitale. Mafakitalewa amadalira kwambiri zida zapaintaneti kuti asonkhanitse ndi kusanthula deta, kupanga mabizinesi kuti agwire bwino ntchito, kupititsa patsogolo zokolola, komanso kupititsa patsogolo malonda ndi ntchito mosalekeza. 5G ikuyembekezeka kuthandiza mabizinesi kuyang'anira bwino kuchuluka kwa zidziwitso zomwe zimapangidwa ndi intaneti ya zinthu, ndikuwongolera mauthenga afupipafupi omwe amafunikira pazantchito zofunika kwambiri monga opaleshoni yothandizidwa ndi loboti kapena kuyendetsa galimoto.
Circulator and isolator ndi chimodzi mwazinthu zazikulu zamasiteshoni a 5G. Njira yonse yolankhulirana yam'manja nthawi zambiri imakhala ndi njira zolumikizirana ndi mafoni, njira yolumikizirana ndi mafoni ndi zida zolumikizirana ndi mafoni. Base station ndi ya zida zoyambira zolumikizirana zam'manja. Base station system nthawi zambiri imakhala ndi RF front-end, base station transceiver ndi base station controller. Kumapeto kwa RF kumayang'anira kusefa ndi kudzipatula, ma transceiver oyambira ndi omwe ali ndi udindo wolandila, kutumiza, kukulitsa ndi kuchepetsa, ndipo wowongolera masiteshoni ali ndi udindo wowunikira ma siginecha, kukonza ndi kuwongolera masiteshoni. Mu netiweki yolumikizira opanda zingwe, circulator imagwiritsidwa ntchito makamaka kupatula chizindikiro chotuluka ndi chizindikiro cholowera cha mlongoti wa base station. Pazinthu zina, wozungulira amatha kukwaniritsa izi ndi zida zina:
1. Itha kugwiritsidwa ntchito ngati mlongoti wamba;
2. Kuphatikizana ndi BPF ndi kufowoketsa mwachangu, imagwiritsidwa ntchito pogawa mafunde;
3. Chotsutsa chotsiriza chimagwirizanitsidwa ndi kunja kwa circulator ngati chodzipatula, ndiko kuti, chizindikirocho ndikulowetsa ndi kutulutsa kuchokera ku doko losankhidwa;
4. Lumikizani ATT yakunja ndikuigwiritsa ntchito ngati circulator ndi ntchito yowunikira mphamvu.
Monga chimodzi mwa zigawo zofunika kwambiri, zidutswa ziwiri zaSamarium Cobalt disc maginitoperekani mphamvu ya maginito yofunikira kukondera pamphambano yodzaza ndi ferrite. Chifukwa cha makhalidwe abwino kwambiri dzimbiri kukana ndi ntchito bata mkulu kwa madigiri 350 ℃, onse SmCo5 ndi Sm2Co17 maginito ntchito circulators kapena odzipatula.
Pogwiritsa ntchito teknoloji yayikulu ya 5G ya MIMO, kugwiritsa ntchito ma circulator ndi odzipatula kwawonjezeka kwambiri, ndipo malo amsika adzafika kangapo pa 4G. Munthawi ya 5G, kufunikira kwa network network ndikokwera kwambiri kuposa kwa 4G. Massive MIMO (Multiple-Input Multiple-Output) ndi imodzi mwamakina ofunikira kuti muwonjezere kuchuluka kwa maukonde. Pofuna kuthandizira lusoli, chiwerengero cha njira za 5G za antenna zidzawonjezeka kwambiri, ndipo chiwerengero cha njira zamtundu umodzi wa antenna chidzawonjezeka kuchokera ku 4 njira ndi 8 njira mu 4G nthawi mpaka 64 njira. Kuwirikiza kawiri kuchuluka kwa mayendedwe kudzetsanso chiwonjezeko chachikulu cha kufunikira kwa ma circulator ofananira ndi odzipatula. Pa nthawi yomweyi, pazosowa zopepuka komanso zazing'ono, zofunikira zatsopano za voliyumu ndi kulemera zimayikidwa patsogolo. Kuonjezera apo, chifukwa cha kusintha kwa maulendo afupipafupi ogwira ntchito, kulowetsa kwa chizindikiro kumakhala kovutirapo ndipo kutsekemera kumakhala kwakukulu, ndipo mphamvu yazitsulo ya 5G idzakhala yapamwamba kuposa ya 4G. Choncho, mu nthawi ya 5G, kugwiritsa ntchito ma circulator ndi odzipatula, ndiyeno maginito a Samarium Cobalt adzawonjezeka kwambiri.
Pakadali pano opanga ma circulator / isolator padziko lonse lapansi akuphatikizapo Skyworks ku USA, SDP ku Canada, TDK ku Japan, HTD ku China, ndi zina zambiri.
