5G, chizvarwa chechishanu nharembozha yekutaurirana tekinoroji chizvarwa chitsva chebroadband mobile communication tekinoroji ine hunhu hwekumhanya kwakanyanya, kunonoka kunonoka uye kubatana kukuru. Ndiyo network network yekuona iyo man-muchina uye chinhu chinongedzo.
IInternet yezvinhu ndiyo inonyanya kubatsirwa ne5G. Simba guru rekutyaira re5G harisi chete kukura kuri kuda kwevatengi kune nekukurumidza network, asiwo kuwanda kwemidziyo yetiweki munharaunda yeindasitiri. Aya maindasitiri anowedzera kuvimba nemidziyo yetiweki kuunganidza uye kuongorora data, kuita kuti mabhizinesi ashande zvakanyanya, kuvandudza kugadzirwa, uye kuenderera mberi nekuvandudza zvigadzirwa nemasevhisi. 5G inotarisirwa kubatsira mabhizinesi kunyatso gadzirisa huwandu huri kukura hweruzivo rwunogadzirwa neInternet yezvinhu, uye kuvandudza mameseji ari padyo anodiwa kumisheni yakakosha masevhisi senge robhoti yakabatsirwa kuvhiyiwa kana kutyaira wega.
Circulator uye isolator ndechimwe chezvinhu zvakakosha zve5G base zviteshi. Iyo yese mobile communication system inowanzo umbwa nenharembozha yekutaurirana masisitimu, nharembozha yekuvhara system uye nharembozha yekutaurirana terminal zvigadzirwa. Base chiteshi ndechemidziyo yekutanga yekufambisa nhare. Base station system inowanzo kuumbwa neRF kumberi-kuguma, base station transceiver uye base station controller. Iyo RF yekumberi-yekupedzisira ine basa rekusefa nekuzviparadzanisa nevamwe, base station transceiver ine basa rekugamuchira chiratidzo, kutumira, kukudza uye kuderedza, uye base station controller ine basa rekuongorora chiratidzo, kugadzirisa uye base station control. Mune isina waya yekuwana network, inotenderera inonyanya kushandiswa kupatsanura inobuda chiratidzo uye yekuisa chiratidzo che base station antenna. Kune chaiwo maapplication, anotenderera anogona kuita zvinotevera mabasa nemamwe maturusi:
1. Inogona kushandiswa se antenna commoner;
2. Mukubatana neBPF nekukasira kunonoka, inoshandiswa mukutsemura kwemafungu;
3. Mushonga wekupedzisira wakabatanidzwa kune kunze kwechitenderedzwa sechinhu chinoparadzana, ndiko kuti, chiratidzo chinopinza uye chinobuda kubva pachiteshi chakasarudzwa;
4. Batanidza kunze kweATT uye uishandise sevhareta ine inoratidzira simba rekuona basa.
Sechimwe chezvikamu zvakakosha, zvidimbu zviviri zveSamarium Cobalt disc maginetiipa iyo magineti inodiwa kuitira kuregeredza iyo ferrite-yakarodha junction. Nekuda kwehunhu hwekusaita ngura uye kugadzikana kwekushanda kwakakwira kusvika 350 ℃ madhigirii, ese SmCo5 uye Sm2Co17 magineti anoshandiswa muma circulator kana isolators.
Nekushandiswa kwe5G yakakura MIMO tekinoroji, kudyiwa kwevanotenderera uye vanoisa voga kwawedzera zvakanyanya, uye nzvimbo yemusika ichasvika kakawanda e4G. Munguva ye5G, chinodiwa chesimba retiweki chakakwira zvakanyanya kupfuura icho che4G. Massive MIMO (Multiple-Input Multiple-Output) ndeimwe yeakakosha matekinoroji ekuvandudza network network. Kuti utsigire tekinoroji iyi, nhamba ye5G antenna chiteshi ichawedzera zvakanyanya, uye nhamba yeimwe chikamu antenna chiteshi ichawedzera kubva ku4 chiteshi uye 8 chiteshi munguva ye4G kusvika ku64 chiteshi. Kupetwa kaviri kwehuwandu hwemachaneti kuchatungamirawo kukuwedzera kukuru kwechido chevanotenderera vanotenderera uye vanozviparadzanisa nevamwe. Panguva imwecheteyo, kune zvinodiwa zvekureruka uye miniaturization, zvitsva zvinodiwa zvehuwandu uye uremu zvinoiswa mberi. Mukuwedzera, nekuda kwekuvandudzwa kwebhendi rekushanda, kupinda kwechiratidzo kwakashata uye kuderedzwa kwakakura, uye base station density ye5G ichave yakakwirira kudarika ye4G. Nokudaro, munguva ye5G, kushandiswa kwema circulators uye isolators, uye ipapo magineti eSamarium Cobalt achawedzera zvakanyanya.
Parizvino vagadziri vakuru veinotenderera / isolator munyika vanosanganisira Skyworks muUSA, SDP muCanada, TDK muJapan, HTD muChina, nezvimwe.
