Kwintsimi enkulu yetekhnoloji, kukho itshatsheli enye engathethiyo eqinisekisa ukuhanjiswa kwedatha okugudileyo kunye noqhagamshelo olungenasiphako kwizicelo ezininzi - iintambo ze-coaxial ze-50 ohm. Nangona abaninzi besenokungaqapheli, eli qhawe elingadunyiswanga lidlala indima ebalulekileyo kumashishini aqala kunxibelelwano ukuya kwi-aerospace. Kule bhlog, siza kutyhila iimfihlakalo zentambo ye-coaxial ye-50 ohm kwaye sihlolisise iinkcukacha zayo zobugcisa, iingenelo kunye nezicelo. Masiqalise olu hambo ukuze siqonde iintsika zoqhagamshelo olungenasiphako!
Iinkcukacha zobugcisa kunye nolwakhiwo:
Intambo ye-coaxial ye-50 ohmyintambo yokudlulisa ene-impedance ephawulekayo ye-50 ohms. Ulwakhiwo lwayo luneeleya ezine eziphambili: umqhubi wangaphakathi, umgcini we-dielectric, isikhuselo sesinyithi kunye nesigqubuthelo sangaphandle esikhuselayo. Umqhubi wangaphakathi, odla ngokwenziwa ngobhedu okanye i-aluminium, uthwala isignali yombane, ngelixa umgcini we-dielectric usebenza njengesigqubuthelo sombane phakathi komqhubi wangaphakathi kunye nesigqubuthelo. Ukhuselo lwesinyithi, olunokuba ngohlobo lwentambo ebhityiweyo okanye ifoyile, lukhusela kuphazamiseko lwangaphandle lwerediyo (RFI). Okokugqibela, isigqubuthelo sangaphandle sibonelela ngokhuseleko loomatshini kwintambo.
Iingenelo ezityhilayo:
1. Ukunyaniseka kweSignali kunye nokulahleka okuphantsi: Ukuphazamiseka kwe-50 ohm kolu hlobo lwentambo kuqinisekisa ukuthembeka kwesignali, kunciphisa ukubonakaliswa kunye nokungafani kwe-impedance. Ibonisa ukuncitshiswa okuphantsi (oko kukuthi ukulahleka kwesignali) kumgama omde, okwenza ifaneleke kwizicelo ze-frequency ephezulu. Olu phawu lokulahleka okuphantsi lubalulekile ekugcineni ukuhanjiswa kwesignali okuthembekileyo nokumgangatho ophezulu.
2. Uluhlu olubanzi lweefrikhwensi: Intambo ye-coaxial ye-50 ohm inokusingatha ububanzi be-spectrum, ukusuka kwi-kilohertz ezimbalwa ukuya kwi-gigahertz ezininzi. Olu buchule luyenza ikwazi ukuhlangabezana neemfuno zezicelo ezahlukeneyo, kubandakanya unxibelelwano, usasazo, uvavanyo lwe-RF kunye nokulinganisa, unxibelelwano lomkhosi kunye nomzi-mveliso weenqwelo moya.
3. Ukukhusela Okuqinileyo: Olu hlobo lwentambo lukhusela ngesinyithi esiqinileyo esibonelela ngokhuseleko olugqwesileyo kuphazamiseko olungafunekiyo lwe-electromagnetic kwaye luqinisekisa ukuhanjiswa kwesignali okucocekileyo. Oku kuyenza ilungele usetyenziso olunokuchaphazeleka yi-RFI, njengeenkqubo zonxibelelwano ezingenazingcingo kunye nokuseta ukulinganisa okuphezulu.
Izicelo ezityebileyo:
1. Unxibelelwano: Kwishishini lonxibelelwano, iintambo ze-coaxial ze-50-ohm zisebenza njengomqolo wokudlulisa ilizwi, ividiyo, kunye nemiqondiso yedatha phakathi kweetowuni zonxibelelwano kunye neeswitshi. Ikwasetyenziswa kakhulu kwiinethiwekhi zeselula, unxibelelwano lwesathelayithi, kunye nabaNiki beeNkonzo ze-Intanethi (ii-ISP).
2. Umkhosi kunye neenqwelo-moya: Ngenxa yokuthembeka kwayo okuphezulu, ilahleko ephantsi kunye nokusebenza kakuhle kokukhusela, olu hlobo lwentambo lusetyenziswa kakhulu kwiindawo zomkhosi kunye neenqwelo-moya. Lusetyenziswa kwiinkqubo zeradar, ii-avionics, ii-UAV (izithuthi zomoya ezingenabantu), iinkqubo zonxibelelwano zomgangatho womkhosi, nokunye.
3. Izixhobo zoshishino nezovavanyo: Ukususela kwii-oscilloscopes ukuya kwii-network analyzers, i-50-ohm coaxial cable isetyenziswa kakhulu kwiilebhu nakwizixhobo zoshishino. Amandla ayo okudlulisa imiqondiso ye-frequency ephezulu kunye nelahleko encinci yenza ukuba ilungele ukusetyenziswa kovavanyo kunye nokulinganisa okungafunekiyo.
ukuququmbela:
Nangona zihlala zinganakwa,Intambo ye-coaxial ye-50 ohmlicandelo elibalulekileyo kumashishini amaninzi, liqinisekisa uqhagamshelo olungenasiphako kunye nokudluliselwa kwedatha okuthembekileyo. Iimpawu zayo zokulahleka okuphantsi, ukhuselo oluqinileyo kunye nobubanzi befrikhwensi ebanzi kwenza ukuba ibe yinxalenye ebalulekileyo kwizicelo zefrikhwensi ephezulu. Eli qhawe elingadunyiswanga lidlala indima ebalulekileyo kuthungelwano lonxibelelwano, ubuchwepheshe beenqwelo moya, izixhobo zovavanyo lwemizi-mveliso kunye nezinye iinkalo. Ngoko ke, masiyixabise imimangaliso ye-50-ohm coaxial cable, evumela uqhagamshelo olungenamthungo kwixesha ledijithali.
