Ivyuma bifatanya RF, nk’ibihimba nyamukuru vyo gutanga ikimenyetso c’incuro nyinshi-, bikoreshwa cane mu bijanye n’itumanaho, mu kirere, mu gupima no gupima, no mu bindi. Ivyo bakora biragira ingaruka zitaziguye ku butungane bw’ikimenyetso, ku bushobozi bwo gutanga amakuru, no ku kwizigirwa kw’urutonde. Iki kiganiro kirasigura mu buryo bubereye uburyo nyamukuru bw’ubuhinga bwo gufatanya ibikoresho vy’ubuhinga bwa none (RF coaxial connectors) bishingiye ku guhitamwo ibikoresho, uguhingura imiterere, uburyo bwo kubikora, n’ugusuzuma ivy’igerageza.
Guhitamwo ibikoresho no gusukura ku ruhande
Ivyo bikoresho vy’ugufatanya RF bivana cane n’uguhitamwo ibikoresho. Igikoresho co hagati gikozwe mu bikoresho bishobora gutwara cane nk’umuringa wa beryllium (BeCu), umuringa wa phosphor (PhBr), canke umuringa w’inzahabu-ushizweko umuringa kugira ngo ushobore guhangana n’ugukorana n’ibintu bitari vyinshi kandi ushobore gutanga ikimenyetso ciza cane. Igikoresho co hanze gikoreshwa kenshi mu cuma kitagira ibara (nk’ica SUS303, SUS316) canke mu muringa (nk’ica H59, H62) kugira ngo kibe gihuye n’inkomezi z’ubuhinga n’ubushobozi bwo gukora. Igikoresho co gukingira umuyagankuba muri rusangi gikozwe mu bikoresho vy’umuyagankuba (PTFE), polyimide (PI), canke ivyuma vy’umuyagankuba kugira ngo bihe umuyagankuba udahinduka kandi udatakaza cane.
Gusukura ku ruhande ni ikintu gihambaye cane kugira ngo ivyuma bifatanya bishobore guhangana n’ugusenyuka no kugira ngo bishobore kwizigirwa. Ivyo bikoresho bikunze gukoreshwa ni ugutera inzahabu (Au), nickel (Ni) canke ifeza (Ag). Inzahabu ikoreshwa cane mu bihe vy’ukwizigirwa vyinshi-kubera ubushobozi bwayo bwiza cane bwo guhangana n’ivyuma bitera umuriro n’ubushobozi buke bwo guhangana n’ugukorana n’ibintu; nickel plating itanga ubushobozi bwiza cane bwo guhangana n’ugusambuka no gukingira hagati y’ibice.
Igishushanyo c'imiterere n'ibipimo nyamukuru
Igishushanyo c’imiterere y’ibifatanya RF bitegerezwa gukurikiza cane inyigisho y’ubuhinga bw’umuyagankuba kugira ngo habeho uguhuza kw’impedansi (mu bisanzwe 50Ω canke 75Ω) kugira ngo bigabanye ivyerekanwa vy’ikimenyetso. Ibintu nyamukuru vy'imiterere birimwo:
1. Impedance Matching: Mu kugenzura neza umurongo w’imbere, uburebure bw’ivyuma, n’umurongo w’inyuma w’imbere, impedance y’ibiranga umurongo w’ugutanga amakuru iraboneka ko ihuye n’ibisabwa vya sisitemu.
2. Gutuma urubuga rwo gukorana rukora neza: Gukoresha ubuhinga bwo gukorana n’abantu bukomeye (nk’umubumbe w’ibara ry’umubiri -na-socket) bituma umubiri ukora neza kandi bikagabanya ubushobozi bwo gukorana n’abantu.
3. Ubushobozi bwo Gukingira: Ubuhinga bwo gukomeza gukoreshwa n’umuyagankuba wo hanze (nk’ugufatanya n’umuyagankuba canke gufunga umuyagankuba) burahagarika neza ivy’uguhungabana kw’umuyagankuba (EMI).
Ikindi, ibipimo nyamukuru nk’urugero rw’incuro, ukubura kw’injiza, igipimo c’umuvuduko uhagaze (VSWR), n’ugukomera (ingendo z’uguhuza) bitegerezwa kugenzurwa biciye mu kwigana no kugerageza.
Uburyo bwo gukora n'ugukora neza
Ivyo gukora ama connectors ya RF coaxial birimwo ubuhinga bwo gukora neza cane, ahanini birimwo intambwe zikurikira:
1. Gukoresha imashini: CNC guhindura canke gutera ibimenyetso vy’ukuri bikoreshwa mu gukora imashini y’imbere n’inyuma, kugira ngo haboneke ukwihanganira ingero mu ±0.01mm.
2. Insulator Molding: Ibikoresho vy’umuyagankuba nka PTFE bishirwako biciye mu gutera injection canke gutera ivyatsi kugira ngo bibe bifatanye neza n’ibikoresho bijana umuyagankuba.
3. Gutera imbere: Uburyo bwo gutera umuyagankuba busaba kugenzura cane uburebure bw’igipfukisho (nk’akarorero, igice c’inzahabu Kirenze canke kingana na 1μm) n’uguhuza kugira ngo ntihagire ukudakomeza mu gutanga ikimenyetso.
Ku bikorwa vy’incuro nyinshi- (nk’imirongo y’imipfunda ya milimetero-), ubuhinga bwo gukora amashini make (nk’ugucapura n’umuyagankuba) na bwo burakenewe kugira ngo ubuhinga bw’amashanyarazi bube bwiza.
Igerageza n'Igenzura ry'Uburyo
Kugira ngo umenye neza ko ibikorwa vy’ivyuma bifatanya bihuye n’ingingo ngenderwako (nka IEC 61169 na MIL-STD-348), birakenewe ko hakorwa igerageza ryinshi n’ugusuzuma, harimwo:
1. Igerageza ry’ubushobozi bw’umuyagankuba: Gupima ukubura kw’injiza, ukubura kw’ugusubira (VSWR), ukurwanya gukorana, n’inyishu y’incuro.
2. Igerageza ry’ubushobozi bw’ubuhinga: Gusuzuma inguvu zo kwinjiza no gukuraho, inguvu zo kugumya, n’ubushobozi bwo guhangana n’uguhungabana/uguhungabana.
3. Igerageza ry’ubushobozi bwo kwimenyereza ibidukikije: Harimwo gucapura ubushuhe bwinshi n’ubuke (-55 degrees gushika kuri +125 degrees ), igerageza ry’ugutera umunyu, n’igerageza ry’ubukonje.
Uburyo bwo kugerageza bwikoresha (nk’ibikoresho vyo gusesangura urusobe rw’ibintu (VNAs)) burashobora gufata neza amakuru ahambaye no kuyobora uguhingura neza.
Kugira ngo ibikoresho bifatanya n’ibindi bihimba vy’umubiri bikore neza, bishingiye ku gukorana neza kw’ubuhinga bw’ibikoresho, ku guhingura ibintu mu buryo bubereye be no ku kugerageza bikomeye. Hamwe n’iterambere rya 5G, ivy’itumanaho ry’inyenyeri, n’ubuhinga bwo gutanga amakuru vyihuta cane-, amahuza azotera imbere aja ku mirongo myinshi (nk’iya terahertz), ubunini buto, n’ugutakaza guke. Gukomeza gutera imbere mu bijanye n’uguhingura n’ugukora birashobora kurushiriza kwongereza ubushobozi bwavyo bwo kwizigirwa no guhindura uko bimeze mu bidukikije bikomeye cane.
