Beijing, pa Ogasiti 21, 2025-M'magawo omwe akukula mofulumira monga 5G communications, satellite internet, and millimeter-wave radar, RF coaxial connectors ndi zinthu zofunika kwambiri pa kutumiza ma siginolo, ndipo kachitidwe kawo kakukhuza kukhazikika kwa makina onse. Chifukwa cha kuchuluka kwa ntchito zama frequency apamwamba, mainjiniya akukumana ndi zovuta kwambiri. Posachedwapa, akatswiri amakampani apereka mwachidule malangizo asanu othandiza othandizira mainjiniya kukhathamiritsa kapangidwe ka zolumikizira, kukonza bwino kuyesa, komanso kukulitsa moyo wa zida.
Langizo 1: Sankhani Kufananiza Koyenera Kwa Impedans
Kulepheretsa kwa zolumikizira za RF coaxial (nthawi zambiri 50Ω kapena 75Ω) ziyenera kufananizidwa bwino ndi dongosolo; Apo ayi, zowonetsera zizindikiro ndi kutaya mphamvu zidzatuluka. "Mu millimeter-mabandi afupipafupi a mafunde (monga pamwamba pa 28GHz), ngakhale kupatuka kwa dimensional 0.1mm kumatha kuwononga kwambiri SWR," adatero mkulu wina waukadaulo pakampani yopanga zolumikizira padziko lonse lapansi. Mainjiniya akuyenera kuyika patsogolo kugwiritsa ntchito mitundu yofananira yoperekedwa ndi wopanga ndikutsimikizira kufanana kwenikweni pogwiritsa ntchito vector network analyzer (VNA).
Tip 2: Samalani kuyeretsa ndi kusunga mawonekedwe kukhudzana.
Zikhomo zolumikizira ndi zitsulo zimakhala zosavuta kutulutsa okosijeni ndi zinyalala zachitsulo pambuyo poika mobwerezabwereza ndikuchotsa, zomwe zimapangitsa kuti pakhale kukhudzana kwambiri. "Timalimbikitsa kugwiritsa ntchito mowa-waulere wa thonje kuti muyeretse zolumikizana ndi kuika zipewa za fumbi m'malo ovuta," adatero mainjiniya omwe akuchita nawo ntchito yopanga 6G. Pazinthu zodalirika kwambiri-zokhala zodalirika (monga zamlengalenga), makulidwe a golidi akuyenera kupitilira 1μm kuti musamavalidwe.
Langizo 3: Konzani zowongolera ma torque.
Kuwonjeza kwambiri kapena kulimbitsa pang'ono kumatha kufupikitsa moyo wa cholumikizira. Deta yamakampani ikuwonetsa kuti torque yovomerezeka ya zolumikizira za SMA ndi 0.7-1.0 N · m, pomwe zolumikizira zolondola za 2.92mm zimafuna kulondola kwa 0.35 N · m. "Kugwiritsa ntchito torque-kang'ono kakang'ono kumachepetsa zolakwika za anthu, zomwe zimakhala zofunika kwambiri popanga zinthu zambiri," anatsindika mkulu wa R&D wa kampani yopanga zida zoyesera.
Langizo 4: Limbikitsani chitetezo champhamvu pama frequency apamwamba.
Mu 5G millimeter wave frequency band, kusakwanira kolumikizira kotchinga kungayambitse zovuta za electromagnetic interference (EMI). Njira zaposachedwa ndi monga zotchingira katatu komanso zotsika-zochepetsa mphamvu yamagetsi-zotsekera nthawi zonse. "Mu labu yathu, tapeza kuti kuwonjezera PTFE (polytetrafluoroethylene) padding kungathandize kuti chitetezo chitetezeke ndi 10dB," adatero mtsogoleri wa gulu lofufuza pa yunivesite.
Langizo 5: Kuthetsa Mavuto Mwamsanga
Dongosolo likakumana ndi zovuta, mainjiniya atha kugwiritsa ntchito -njira zitatu kuti apeze zovuta zolumikizira:
1. Kuyang'ana m'maso: Yang'anirani zikhomo zopindika kapena zosenda;
2. Kuyesa kwa nthawi ya reflectometry (TDR): Pezani ma discontinuities a impedance;
3. Njira yosinthira: Bwezerani cholumikizira chomwe mukuchiganizira kuti mutsimikizire vutolo.
"Zolakwika zazikulu-zimachitika nthawi zambiri pamalumikizidwe atatu oyamba. Kuika patsogolo malowa kumatha kupulumutsa nthawi yopitilira 50% yamavuto," akulangiza motero injiniya wamkulu wa RF.
Mchitidwe Wamakampani: Miniaturization ndi ma frequency apamwamba amasinthira limodzi
Pamene kukula kwa phukusi la chip kukucheperachepera, kufunikira kwa zolumikizira zazing'ono kwambiri, ngakhale 1.0mm ndi 0.8mm, kukukulirakulira. Nthawi yomweyo, ukadaulo wa waveguide-to{5}}coaxial conversion ukadaulo wothandizira ma frequency opitilira 110 GHz wakhala malo ofufuzira ndi chitukuko. Akatswiri amaneneratu kuti zolumikizira zanzeru zolipirira kutentha kophatikizana zitha kukhala zofala m'zaka zisanu zikubwerazi.
Mapeto
Kuwongolera magwiridwe antchito a RF coaxial zolumikizira kumafuna kuphatikiza kwakukulu kwa malingaliro ndi machitidwe. Kudziwa bwino njira zomwe zili pamwambazi sikungowonjezera luso la uinjiniya komanso kukhazikitsa maziko olimba a-zothandizira zoyankhulirana za m'badwo wina. Monga momwe katswiri wina wamakampani amanenera, "Zambiri zimatsimikizira kupambana kapena kulephera kwa ma siginoloji apamwamba kwambiri-, ndipo zolumikizira zili pamtima pazambiri izi."
