Izixhumi ze-RF coaxial ziyizingxenye ze-elekthronikhi ezibalulekile ezisetshenziselwa ukudlulisa{0}}amasignali amaza aphezulu. Umsebenzi wabo oyinhloko ukuhlinzeka ngoxhumano lukagesi oluthembekile phakathi kwamadivayisi kuyilapho kugcinwa ubuqotho besignali. Idizayini yabo yesakhiwo ithinta ngokuqondile ukusebenza kokudlulisela futhi ngokuyinhloko ihlanganisa izingxenye ezibalulekile ezifana ne-conductor yangaphakathi, i-conductor yangaphandle, i-dielectric support, kanye nezindlu zangaphandle.
I-conductor yangaphakathi, ingxenye emaphakathi yesixhumi, ngokuvamile yenziwe ngengxubevange yethusi (njenge-beryllium yethusi noma i-phosphor bronze) futhi imbozwe ngegolide noma isiliva ukuze kuthuthukiswe ukusebenza kahle nokungagqwali. Ukunemba kwe-conductor yangaphakathi kuthinta ngokuqondile ukusebenza kahle kokudluliselwa kwesignali, ngakho-ke ukubekezelela kwayo kobukhulu nokuqedwa kwendawo kufanele kulawulwe ngokuqinile.
Ikhondaktha yangaphandle, esebenza njengesihlangu, ivamise ukwenziwa ngengxubevange yethusi noma insimbi engagqwali futhi iphinde ihlanganiswe ukuze kuthuthukiswe ukumelana ne-oxidation. Umsebenzi oyinhloko we-conductor yangaphandle ukunciphisa ukuphazamiseka kwe-electromagnetic (EMI) nokuvikela isignali kumsindo wangaphandle ngesikhathi sokudlulisa. Ivamise ukusebenzisa ukuxhuma okunentambo noma i-bayonet ukuze kuzuzwe ukuhlangana okuvikelekile komshini.
Usekelo lwe-dielectric, olutholakala phakathi kwamakhondakta angaphakathi nangaphandle, ngokuvamile lwenziwa-ngezinto ezilahlekayo eziphansi njenge-polytetrafluoroethylene (PTFE), i-ceramic, noma i-polyethylene. Usekelo lwe-dielectric aligcini nje ngokuvikela indawo ye-conductor yangaphakathi kodwa futhi inquma izici zokuvimba isixhumi (isb, 50Ω noma 75Ω), ngaleyo ndlela kuthinte iphethini yokudlulisela isignali.
Izindlu zihlinzeka ngokuvikeleka komshini kanye nokuvala imvelo futhi ngokuvamile zenziwe nge-aluminium alloy noma insimbi engagqwali, e-anodized noma epuletiwe ukuze iqine. Idizayini yezindlu nayo idinga ukucabangela kalula ukufakwa nokususwa kanye nokuhambisana kwemvelo, njengokuvimbela amanzi nokuvikela uthuli.
Ngaphezu kwalokho, idizayini yesakhiwo yezixhumi ze-RF coaxial kufanele icabangele izici ezifana nokumelana nokuxhumana, i-voltage Stand Wave ratio (VSWR), kanye nempilo yemishini ukuze kuqinisekiswe ukuzinza nokuthembeka{0}}ezinhlelweni zokusebenza zemvamisa. Ngokuthuthukisa okokusebenza nezinqubo zengxenye ngayinye, izixhumi zesimanje ze-RF coaxial zihlangabezana nezidingo zobuchwepheshe-zezinhlelo zokusebenza eziphezulu, kusukela kumishini yezokuxhumana kuye emkhathini.
