Ihitamo rya RF coaxial ihuza rigomba gusuzuma ibisabwa nibikorwa byubukungu.Imikorere igomba kuba yujuje ibisabwa ibikoresho byamashanyarazi.Mu bukungu, igomba kuba yujuje ibisabwa byubuhanga bwagaciro.Ihame, ibintu bine bikurikira bigomba gusuzumwa muguhitamo abahuza.Ibikurikira, reka turebe.
Umuhuza wa BNC
(1) Imigaragarire ihuza (SMA, SMB, BNC, nibindi)
(2) Imikorere y'amashanyarazi, insinga n'insinga
(3) Ifishi yo guhagarika (ikibaho cya PC, umugozi, akanama, nibindi)
(4) Imiterere ya mashini no gutwikira (igisirikare nubucuruzi)
1 interface Imigaragarire
Imigaragarire ihuza ubusanzwe igenwa nuburyo ikoreshwa, ariko igomba kuba yujuje ibyangombwa byamashanyarazi nubukanishi icyarimwe.
Ubwoko bwa BMA buhuza bukoreshwa muguhuza buhumyi sisitemu ntoya ya microwave hamwe na frequence igera kuri 18GHz.
Ihuza rya BNC ni ubwoko bwa bayonet ihuza, ikoreshwa cyane cyane kuri RF ihuza imirongo iri munsi ya 4GHz, kandi ikoreshwa cyane muri sisitemu y'urusobe, ibikoresho hamwe na mudasobwa ihuza imirima.
Usibye screw, interineti ya TNC isa n'iya BNC, irashobora gukoreshwa kuri 11GHz kandi ifite imikorere myiza mugihe cyo kunyeganyega.
SMA screw ihuza ikoreshwa cyane mubyindege, radar, itumanaho rya microwave, itumanaho rya digitale nibindi bikorwa bya gisivili na gisivili.Inzitizi zayo ni 50 Ω.Iyo ukoresheje umugozi woroshye, inshuro ziri munsi ya 12.4GHz.Iyo ukoresheje kabili ya kabili, inshuro ntarengwa ni 26.5GHz.75 Ω ifite ibyifuzo byinshi byo gukoresha muburyo bwitumanaho.
Ingano ya SMB ni ntoya kuruta iya SMA.Kugirango ushiremo uburyo bwo kwifungisha no koroshya guhuza byihuse, porogaramu isanzwe ni itumanaho rya digitale, ariryo risimbuza L9.Ubucuruzi 50N ihura na 4GHz, na 75 Ω ikoreshwa kuri 2GHz.
SMC isa na SMB kubera screw yayo, itanga imikorere ikomeye yubukanishi hamwe nintera yagutse.Ikoreshwa cyane mubisirikare cyangwa bihindagurika cyane.
N-ubwoko bwa screw ihuza ikoresha umwuka nkibikoresho byigiciro hamwe nigiciro gito, impedance ya 50 Ω na 75 Ω, ninshuro zigera kuri 11 GHz.Ubusanzwe ikoreshwa mumiyoboro yakarere, kohereza itangazamakuru nibikoresho byipimisha.
Ihuza rya MCX na MMCX ryatanzwe na RFCN ni rito mubunini kandi ryizewe mubiganiro.Nibicuruzwa byatoranijwe kugirango byuzuze ibisabwa byimbaraga na miniaturizasiya, kandi bifite ibyifuzo byinshi byo gusaba.
2 performance Imikorere y'amashanyarazi, insinga n'insinga
A. Impedance: Umuhuza agomba guhuza impedance ya sisitemu na kabili.Twabibutsa ko amahuza yose adahuza yujuje impedance ya 50 Ω cyangwa 75 Ω, kandi kudahuza kwa impedance bizaganisha kumikorere ya sisitemu.
B. Umuvuduko: menya neza ko ntarengwa ishobora kwihanganira voltage yumuhuza idashobora kurenga mugihe ikoreshwa.
C. Inshuro ntarengwa yo gukora: buri muhuza afite imipaka ntarengwa yo gukora, kandi bimwe mubucuruzi cyangwa 75n bishushanya bifite byibuze ntarengwa byakazi.Usibye imikorere y'amashanyarazi, buri bwoko bwa interineti bufite imiterere yihariye.Kurugero, BNC ni bayonet ihuza, yoroshye kuyishyiraho kandi ihendutse kandi ikoreshwa cyane mumashanyarazi make;Urukurikirane rwa SMA na TNC rwahujwe nimbuto, zujuje ibisabwa by ibidukikije bihindagurika cyane kubihuza.SMB ifite imikorere yo guhuza byihuse no guhagarika, bityo irarushijeho gukundwa nabakoresha.
D. Umugozi: Kubera imikorere yayo ikingira, insinga ya TV isanzwe ikoreshwa muri sisitemu itekereza gusa inzitizi.Porogaramu isanzwe ni antenne ya TV.
Umugozi woroshye wa TV ni variant ya kabili ya TV.Ifite impagarike ikomeza ningaruka nziza yo gukingira.Irashobora kugororwa kandi ifite igiciro gito.Irakoreshwa cyane mubikorwa bya mudasobwa, ariko ntishobora gukoreshwa muri sisitemu isaba imikorere ikingira cyane.
Intsinga ihindagurika ikuraho inductance na capacitance, zikoreshwa cyane mubikoresho ninyubako.
Umugozi woroshye wa coaxial wabaye umugozi wo gufunga cyane kubera imikorere yihariye.Coaxial isobanura ko ikimenyetso nuyobora hasi biri kumurongo umwe, naho umuyobozi winyuma agizwe ninsinga nziza, bityo nanone yitwa umugozi wa coaxial.Iyi nsinga ifite ingaruka nziza zo gukingira umuyobozi mukuru kandi ingaruka zayo zo gukingira ziterwa nubwoko bwinsinga zometse hamwe nubunini bwurwego.Usibye imbaraga zo guhangana n’umuvuduko mwinshi, iyi nsinga irakenewe no gukoreshwa kuri frequency nyinshi nubushyuhe bwinshi.
Intsinga ya Semi-rigid coaxial isimbuza igipande cyometse hamwe nigikonoshwa cyigituba, kigakora neza ingaruka mbi zo gukingira nabi kwinsinga zometse kumurongo mwinshi.Intsinga ya Semi-rigid ikoreshwa mubisanzwe.
E. Iteraniro ryumugozi: Hariho uburyo bubiri bwingenzi bwo kwishyiriraho: (1) gusudira umuyobozi mukuru no gusunika urwego rukingira.(2) Kunyunyuza umuyobozi mukuru hamwe nigice cyo gukingira.Ubundi buryo bukomoka muburyo bubiri bwavuzwe haruguru, nko gusudira umuyobozi mukuru no guhonyora urwego rukingira.Uburyo (1) bukoreshwa mubihe bidafite ibikoresho byihariye byo kwishyiriraho;Bitewe nubushobozi buhanitse kandi bwizewe bwo kurangiza uburyo bwo guteranya uburyo bwo guterana, hamwe nigishushanyo cyigikoresho cyihariye gishobora gutobora gishobora kwemeza ko buri gice cya maggot cyateranijwe ari kimwe, hamwe niterambere ryibikoresho biciriritse bidahenze, igikoresho cyo gukingira umuyobozi wo gusudira ikigo azarushaho gukundwa.
3 form Ifishi yo guhagarika
Umuhuza arashobora gukoreshwa kumurongo wa coaxial ya RF, imbaho zumuzingo zanditse hamwe nandi masano.Imyitozo yerekanye ko ubwoko bumwe bwihuza buhuye nubwoko bumwe bwa kabili.Mubisanzwe, umugozi ufite diameter ntoya yo hanze uhujwe nuduce duto twa coaxial nka SMA, SMB na SMC.4 structure Imiterere yimashini no gutwikira
Imiterere yumuhuza izagira ingaruka cyane kubiciro byayo.Igishushanyo cya buri muhuza kirimo urwego rwa gisirikare nubucuruzi bwubucuruzi.Igipimo cya gisirikare gikora ibice byose bikozwe mu muringa, insimburangingo ya polytetrafluoroethylene, hamwe no gushyiramo zahabu imbere n’inyuma ukurikije MIL-C-39012, hamwe n’imikorere yizewe.Igishushanyo mbonera cyubucuruzi gikoresha ibikoresho bihendutse nko guta umuringa, kubika polypropilene, gutwika ifeza, nibindi.
Ihuza rikozwe mu muringa, umuringa wa beryllium hamwe nicyuma.Umuyoboro wo hagati usanzwe usizwe na zahabu kubera kutarwanya kwinshi, kurwanya ruswa no guhumeka neza.Igipimo cya gisirikare gisaba isahani ya zahabu kuri SMA na SMB, hamwe na feza kuri N, TNC na BNC, ariko abayikoresha benshi bahitamo isahani ya nikel kuko ifeza yoroshye okiside.
Insulator zikoreshwa cyane zirimo polytetrafluoroethylene, polypropilene na polystirene ikaze, muri zo polytetrafluoroethylene ifite imikorere myiza yo gukingira ariko igiciro kinini cyo gukora.
Ibikoresho nuburyo bwumuhuza bigira ingaruka kubikorwa byo gutunganya no gukora neza.Kubwibyo, abakoresha bagomba guhitamo neza umuhuza hamwe nibikorwa byiza nigipimo cyibiciro ukurikije aho basaba.
