Pekin, ku ya 21 Kanama 2025 - Mu iterambere ryihuta cyane nk'itumanaho rya 5G, interineti ya satelite, na milimetero - radar ya radiyo, umuhuza wa coaxial RF ni ibintu by'ingenzi mu kohereza ibimenyetso, kandi imikorere yabyo igira ingaruka ku buryo butaziguye kuri sisitemu yose. Hamwe nubwiyongere bwibisabwa kuri progaramu nyinshi, injeniyeri zirahura nibibazo bikomeye. Vuba aha, impuguke mu nganda zavuze muri make inama eshanu zifatika zifasha injeniyeri guhuza igishushanyo mbonera, kunoza imikorere yikizamini, no kongera ubuzima bwibikoresho.
Impanuro ya 1: Hitamo Guhuza Iburyo Bwiza
Inzitizi ya RF coaxial ihuza (mubisanzwe 50Ω cyangwa 75Ω) igomba guhuzwa neza na sisitemu; bitabaye ibyo, ibimenyetso byerekana no gutakaza ingufu bizavamo. Umuyobozi wa tekinike mu ruganda mpuzamahanga ruhuza imiyoboro yagize ati: "Muri milimetero - imirongo yumurongo wumurongo (urugero, hejuru ya 28GHz), ndetse no gutandukana kwa 0.1mm bishobora gutera ihungabana rikomeye muri SWR". Ba injeniyeri bagomba gushyira imbere bakoresheje imiterere isanzwe ya impedance itangwa nuwabikoze kandi bakagenzura ihuye ryukuri bakoresheje isesengura ryurubuga (VNA).
Inama 2: Witondere gusukura no kubungabunga interineti.
Amashanyarazi hamwe nisogisi bikunda guhura na okiside hamwe n imyanda yicyuma nyuma yo gushiramo no kuyikuramo inshuro nyinshi, bigatuma abantu barwanya guhura. Injeniyeri wagize uruhare mu iterambere rya 6G, yagize ati: "Turasaba ko dukoresha inzoga - ku buntu kugira ngo dusukure umubano kandi dushyireho umukungugu ahantu h'ahantu habi." Kubirebire - ibintu byiringirwa (nkibisabwa mu kirere), uburebure bwa zahabu bugomba kurenza 1 mm kugirango byongere imbaraga zo kwambara.
Inama 3: Hindura uburyo bwo kugenzura umuriro.
Kurenza urugero cyangwa kwiyemeza birashobora kugabanya ubuzima bwihuza. Inganda zerekana ko urumuri rusabwa kubahuza SMA ari 0.7-1.0 N · m, mugihe 2.92mm ihuza neza bisaba 0.35 N · m. Umuyobozi wa R&D w’uruganda rukora ibikoresho byo kwipimisha yashimangiye ati: "Gukoresha itara - rigabanya imipaka rigabanya amakosa y’abantu, cyane cyane mu musaruro rusange."
Impanuro ya 4: Kunoza uburyo bwo gukingira inshuro nyinshi.
Muri milimetero 5G yumurongo wumurongo wumurongo, udahuza uhuza gukingira neza birashobora gukurura ibibazo bya electromagnetic intervention (EMI). Ibisubizo biheruka birimo gukingirwa inshuro eshatu no hasi - dielectric - ibikoresho byo guhora. Umuyobozi w'itsinda ry'ubushakashatsi muri kaminuza yagize ati: "Muri laboratoire yacu, twasanze kongeramo padi ya PTFE (polytetrafluoroethylene) bishobora guteza imbere ingabo zirenga 10dB".
Inama 5: Gukemura vuba
Iyo sisitemu yiboneye ibimenyetso bidasanzwe, injeniyeri zirashobora gukoresha uburyo butatu - intambwe kugirango tumenye ibibazo byihuza:
1. Kugenzura amashusho: Itegereze ibipapuro byunamye cyangwa ibishishwa;
2. Igihe cyagenwe cyerekana (TDR) ikizamini: Menya guhagarika impedance;
3. Uburyo bwo gusimbuza: Simbuza abakekwaho guhuza kugirango umenye ikibazo.
Injeniyeri mukuru wa RF agira ati: "Amakosa menshi - akunze kugaragara ku masangano atatu ya mbere ahuza. Gushyira imbere aha hantu birashobora kuzigama hejuru ya 50% yo gukemura ibibazo".
Inganda zinganda: Miniaturisation hamwe ninshuro nyinshi zihurira hamwe
Mugihe ingano ya chip igabanuka, ibisabwa kuri ultra - ihuza rito, ndetse 1.0mm na 0.8mm, biriyongera cyane. Muri icyo gihe, umurongo wa - kugeza kuri - tekinoroji yo guhinduranya ya coaxial ishyigikira imirongo iri hejuru ya 110 GHz yahindutse ubushakashatsi n’iterambere. Abahanga bavuga ko abahuza ubwenge bafite indishyi z’ubushyuhe bazagenda biba rusange mu myaka itanu iri imbere.
Umwanzuro
Kunoza imikorere ya RF coaxial ihuza bisaba guhuza byimazeyo ibitekerezo nibikorwa. Kumenya tekinike zavuzwe haruguru ntabwo bizamura imikorere yubuhanga gusa ahubwo bizanashyiraho urufatiro rukomeye rwibikorwa remezo byitumanaho -. Nkuko impuguke imwe mu nganda yabivuze, "Ibisobanuro byerekana intsinzi cyangwa gutsindwa kw'ibimenyetso byo hejuru -, kandi abahuza ni bo shingiro ry’ibi bisobanuro."
