Emkhakheni omkhulu wobuchwepheshe, kunompetha oyedwa othule oqinisekisa ukudluliswa kwedatha okushelelayo nokuxhumana okungenasici ezinhlelweni eziningi zokusebenza - izintambo ezingama-50 ohm coaxial.Nakuba abaningi bengase bangaboni, leli qhawe elingaculwa lidlala indima ebalulekile ezimbonini kusukela kwezokuxhumana ngocingo kuye emkhathini.Kule bhulogi, sizodalula izimfihlakalo zentambo ye-coaxial engu-50 ohm futhi sihlole imininingwane yayo yobuchwepheshe, izinzuzo nezinhlelo zokusebenza.Masiqale lolu hambo ukuze siqonde izinsika zokuxhuma okungenamthungo!
Imininingwane yobuchwepheshe nesakhiwo:
50 ohm intambo ye-coaxialulayini wokudlulisela onokuphazamiseka kwesici okungu-50 ohms.Isakhiwo sawo siqukethe izingqimba ezine eziyinhloko: i-conductor yangaphakathi, insulator ye-dielectric, isihlangu sensimbi nesivikelo sangaphandle sokuzivikela.I-conductor yangaphakathi, ngokuvamile eyenziwe ngethusi noma nge-aluminium, iphethe isignali kagesi, kuyilapho isivikelo se-dielectric sisebenza njengesivikeli sikagesi phakathi kwekhondatha yangaphakathi nesihlangu.Ukuvikela insimbi, okungaba ngocingo olulukiwe noma ucwecwe, kuvikela ekuphazamisekeni kwefrikhwensi yomsakazo wangaphandle (RFI).Ekugcineni, i-sheath yangaphandle inikeza ukuvikelwa komshini kukhebula.
Ukuveza izinzuzo:
1. Ubuqotho Besiginali kanye Nokulahlekelwa Okuphansi: Isici sesici esingu-50 ohm sokuthimbezeleka kwalolu hlobo lwekhebula kuqinisekisa ubuqotho besignali obuphelele, kunciphisa ukuboniswa kanye nokungafani kokuphazamiseka.Ibonisa ukuncipha okuphansi (okungukuthi ukulahleka kwesignali) kumabanga amade, okuyenza ifanelekele izinhlelo zokusebenza zefrikhwensi ephezulu.Lesi sici sokulahlekelwa okuphansi sibalulekile ekugcineni ukudluliswa kwesignali okuthembekile kanye nekhwalithi ephezulu.
2. Ububanzi befrikhwensi ebanzi: 50 ohm ikhebula le-coaxial lingakwazi ukuphatha i-spectrum ebanzi, kusukela ku-kilohertz embalwa kuya kumagigahertz ambalwa.Lokhu kuguquguquka kuyenza ikwazi ukuhlangabezana nezidingo zezinhlelo zokusebenza ezahlukene, okuhlanganisa ezokuxhumana, ukusakaza, ukuhlolwa nokulinganisa kwe-RF, ukuxhumana kwezempi kanye nemboni ye-aerospace.
3. Isivikelo Esiqinile: Lolu hlobo lwekhebula luhlanganisa isivikelo sensimbi esiqinile esinikeza isivikelo esihle kakhulu ekuphazamisekeni okungafunwa nguzibuthe kagesi futhi siqinisekise ukudluliswa kwesignali ehlanzekile.Lokhu kuyenza ilungele izinhlelo zokusebenza ezithambekele ku-RFI, njengamasistimu okuxhumana angenantambo kanye nokusetha kokulinganisa kwamafrikhwensi aphezulu.
Izinhlelo zokusebenza ezinothile:
1. Ezokuxhumana: Embonini yezokuxhumana, izintambo ezingama-50-ohm coaxial zisebenza njengomgogodla wokudlulisa izimpawu zezwi, zevidiyo, nedatha phakathi kwemibhoshongo yokuxhumana namaswishi.Ibuye isetshenziswe ngokujwayelekile kumanethiwekhi weselula, ukuxhumana ngesathelayithi, nabahlinzeki besevisi ye-inthanethi (ISPs).
2. Ibutho lezempi kanye ne-aerospace: Ngenxa yokuthembeka kwayo okuphezulu, ukulahlekelwa okuphansi nokusebenza okuhle kakhulu kokuvikela, lolu hlobo lwekhebula lusetshenziswa kakhulu emkhakheni wezempi kanye ne-aerospace.Isetshenziswa ezinhlelweni ze-radar, ama-avionics, ama-UAV (izimoto zasemoyeni ezingenamuntu), izinhlelo zokuxhumana zezinga lezempi, nokunye.
3. Imishini yezimboni neyokuhlola: Kusukela kuma-oscilloscopes kuya kubahlaziyi benethiwekhi, ikhebula le-coaxial elingu-50-ohm livame ukusetshenziswa kumalabhorethri namathuluzi ezimboni.Ikhono layo lokudlulisa amasiginali wefrikhwensi ephezulu ngokulahlekelwa okuncane kuyenza ifaneleke ekuhlolweni okudingayo nezinhlelo zokusebenza zokulinganisa.
Ekuphetheni:
Nakuba ngokuvamile kunganakwa,50 ohm intambo ye-coaxialiyingxenye ebalulekile ezimbonini eziningi, eqinisekisa ukuxhumana okungenasici kanye nokudluliswa kwedatha okuthembekile.Izici zayo zokulahlekelwa okuphansi, isivikelo esiqinile kanye nobubanzi befrikhwensi ebanzi kuyenza ibe ingxenye ebaluleke kakhulu yezinhlelo zokusebenza zefrikhwensi ephezulu.Leli qhawe elingaculwa lidlala indima ebalulekile kumanethiwekhi ezokuxhumana, ubuchwepheshe be-aerospace, imishini yokuhlola yezimboni neminye imikhakha.Ngakho-ke, asibonge izimanga zekhebuli ye-coaxial engu-50-ohm, isinikezeli esithulile sokuxhuma okungenazihibe enkathini yedijithali.
