Beijing, 21 Myandagaro 2025-Mu bikorwa biriko biratera imbere cane nk’ivy’itumanaho rya 5G, internet y’inyenyeri, na radar y’imipfunda ya milimetero-, ibikoresho bifatanya RF ni ibihimba nyamukuru vyo gutanga ikimenyetso, kandi ubushobozi bwavyo buragira ingaruka zitaziguye ku gushikama kw’urutonde rwose. Kubera ko abantu benshi bashaka gukoresha ibikoresho bikoreshwa incuro nyinshi, abahinga bariko barashikirwa n’ingorane zikomeye kuruta. Vuba aha, abahinga mu vy’ivyo bikoresho baravuze mu ncamake impanuro zitanu ngirakamaro zo gufasha abahinga gukora neza ibikoresho bifatanya, gutuma ibikoresho bikora neza kuruta, no kwongera ubuzima bw’ibikoresho.
Impanuro ya 1: Hitamwo Impedance Ihuye neza
Impedansi y’ibifatanya RF (mu bisanzwe 50Ω canke 75Ω) itegerezwa kuba ihuye neza n’ivyo bikoresho; ahandi ho, ivyerekanwa vy’ikimenyetso n’ugutakaza ububasha bizovamwo. Umuyobozi w’ivy’ubuhinga mw’ishirahamwe mpuzamakungu rikora ibikoresho bifatanya amakuru yavuze ati: “Mu mirongo y’imirongo y’imirongo y’imipfunda y’imirongo y’imirongo y’imirongo y’imirongo y’imirongo (nk’akarorero, hejuru ya 28GHz), mbere n’ugukevya kw’ingero kwa 0,1mm birashobora gutuma SWR ihungabana cane.” Abahinga bakwiye gushira imbere gukoresha ibigereranyo vy’uburemere busanzwe bitangwa n’umuhinguzi no kugenzura ukuntu bihuye vy’ukuri bakoresheje igikoresho co gusesangura uruja n’uruza rw’ibintu (VNA).
Impanuro ya 2: Niwitwararike gusukura no kubungabunga urubuga rwo guhuriramwo.
Ivyuma bifatanya n’ibikoresho bifatanya birashobora guhinduka ivyuma n’ibisigazwa vy’ivyuma inyuma yo gusubiramwo no kubikuramwo, ivyo bikaba bituma umuntu ashobora guhangana n’ivyo akora. Injeniyeri umwe afise uruhara mu gutegura igikoresho ca 6G yavuze ati: “Turahimiriza gukoresha igitambaro co mu ipampa kitagira inzoga-mu gusukura aho umuntu akora no gushiramwo ibipfukisho vy’inkungugu mu bidukikije bikomeye.” Ku bikorwa vy’ukwizigirwa cane (nk’ibikorwa vyo mu kirere), uburebure bw’inzahabu bukwiye kurenga 1μm kugira ngo bube bwiza bwo guhangana n’ugusambuka.
Impanuro ya 3: Nukoreshe neza uburyo bwo kugenzura umuvuduko wo gushiramwo.
Gukomeza cane canke gukomeza bike birashobora kugabanya ubuzima bw’ivyuma bifatanya. Amakuru y’inganda yerekana ko umuvuduko w’amashanyarazi usabwa ku bikoresho bifatanya SMA ari 0.7–1.0 N·m, mu gihe ibikoresho bifatanya 2.92mm vy’ukuri bisaba ukuri kwa 0.35 N·m. Umuyobozi w’ubushakashatsi n’iterambere ry’ishirahamwe rimwe rikora ibikoresho vyo gupima yashimikiye ko ati: “Gukoresha urufunguruzo rufise umuvuduko muto-bigabanya amakosa y’abantu, ivyo bikaba ari ngirakamaro canecane mu guhingura ibintu vyinshi.”
Impanuro ya 4: Nunongere ubushobozi bwo gukingira ku mirongo myinshi.
Mu nzira y’imirongo y’imirongo ya milimetero 5G, ubushobozi budahagije bwo gukingira ivyuma bishobora gutuma haba ibibazo vy’uguhungabana kw’umuyagankuba (EMI). Ivyo bisubizo bishasha birimwo uburinzi butatu n’ibikoresho vy’ugukingira umuyagankuba bifise ubushobozi buke-buhoraho. Umuyobozi w’umugwi w’abashakashatsi wo muri kaminuza yavuze ati: “Mu laboratwari yacu, twabonye ko kwongerako ivyuma bita PTFE (polytetrafluoroethylene) bishobora gutuma ubushobozi bwo gukingira bugenda buragabanuka ku buryo burenga 10dB.”
Impanuro ya 5: Gutorera umuti ingorane vyihuse
Iyo sisitemu ishikiwe n'ibimenyetso bitari vyo, abahinga bashobora gukoresha uburyo bw'intambwe zitatu -kugira ngo bamenye ibibazo vy'ihuriro:
1. Gusuzuma n’amaso: Niwihweze ko ata bipimo bipfutse canke ko ata bipfukisho bipfutse;
2. Igerageza ry’igihe (TDR): Gutora aho impedance idakomeza;
3. Uburyo bwo gusubirira: Gusubirira igihuza wikekwa kugira ngo ugenzure ikibazo.
"Amakosa y'incuro nyinshi-akenshi aba ku nzira zitatu za mbere z'uguhuza. Gushira imbere ivyo bibanza birashobora kuzigama igihe kirenga 50% co gutorera umuti ingorane," ni ko injeniyeri mukuru wa RF agira inama.
Ivyiyumviro vy'inganda: Guhindura ibintu bitobito n'incuro nyinshi birahurirana
Uko ubunini bw'ibipapuro vy'ibice bugenda buragabanuka, niko n'ugusaba ibifatanya bitobito cane, mbere n'ivya 1.0mm na 0.8mm, biriko birakura cane. Muri ico gihe nyene, ubuhinga bwo guhindura amajwi bushingiye ku nzira y’umuyaga-to-axial bushigikira incuro ziri hejuru ya 110 GHz bwacitse ikibanza c’ubushakashatsi n’iterambere. Abahinga bavuga ko ibikoresho vy’ubwenge bifatanya n’ibindi bikoresho bifise ubushobozi bwo gusubiza inyuma ubushuhe bizogenda biramenyekana buhorobuhoro mu myaka itanu iri imbere.
Iciyumviro
Kugira ngo ama connecteurs coaxial ya RF akore neza cane bisaba ko umuntu akora cane inyigisho n’ibikorwa. Kumenya neza ubuhinga buvuzwe haruguru ntibizotuma ubuhinga bukora neza gusa, ariko kandi bizotuma habaho umushinge ukomeye w’ibikorwa remezo vy’itumanaho vy’uruvyaro ruzokurikira. Nk'uko umuhinga mu vy'ubuhinga umwe yabivuze, "Ibisobanuro ni vyo bigena ukuroranirwa canke ukunanirwa kw'ibimenyetso vy'incuro nyinshi, kandi ibihuza ni vyo biri mu mutima w'ivyo bisobanuro."
