Izixhumi ze-coaxial ze-RF, njengezingxenye ezibalulekile kwezokuxhumana zesimanje namasistimu kagesi, zidlala indima engenakuthathelwa indawo-ekudlulisweni kwemvamisa yamasignali. Umsebenzi wabo oyinhloko ukuhlinzeka ngoxhumano olusebenzayo noluzinzile lwamasiginali e-RF kuyilapho kucindezela ngempumelelo ukuphazamiseka kazibuthe nokuqinisekisa ukwethembeka kohlelo.
Ngobuchwepheshe, izixhumi ze-coaxial ze-RF zisebenzisa ukwakheka okugxilile okuyingqayizivele-izakhiwo{1}}zezendlalelo ezintathu ezihlanganisa i-conductor yangaphakathi, i-dielectric layer, kanye ne-conductor yangaphandle{2}}ukudala indawo eqinile yokuvikela i-electromagnetic. Lesi sakhiwo sihlanganisa ngokuqinile isignali yamanje endaweni ye-dielectric evikelayo phakathi kwama-conductor angaphakathi nangaphandle, kunciphisa kakhulu ukulahlekelwa kwemisebe yesignali. Uma ukufaniswa kwe-impedance kuzo zombili iziphetho zesixhumi kufinyelela inani elijwayelekile (imvamisa engu-50Ω noma 75Ω), amaza abonisiwe ayancishiswa, okuqinisekisa ubuqotho besignali. Lesi sici sibaluleke kakhulu kumabhendi efrikhwensi ye-microwave (300MHz ukuya ku-300GHz), okunomthelela ngokuqondile ekutholeni ukunemba kanye nekhwalithi yokudlulisela idatha yamasistimu afana ne-radar nokuxhumana ngesathelayithi.
Kuzinhlelo zokusebenza ezingokoqobo, izixhumi ze-RF coaxial zibonisa-inani lobukhulu obuhlukahlukene. Eziteshini eziyisisekelo zokuxhumana ezingenazintambo, izixhumi zinesibopho sokusabalalisa amandla kanye nokudluliswa kwamasignali phakathi kwamamojula e-RF. Ukuzinza kokumelana kwabo nokuxhumana kuthinta ngokuqondile ukusebenza kahle kokudluliselwa kwesiteshi. Imboni yokuhlola neyokulinganisa incike{4}}ezixhumi ezinembayo eziphezulu ukuze kulinganiswe futhi kuxhunywe okokusebenza okufana nabahlaziyi be-spectrum nabahlaziyi benethiwekhi. Ngisho namaphutha amancane okuxhumana angabangela amaphutha okulinganisa amaphuzu amaningana. Izixhumi ezisetshenziswa kumishini ye-aerospace kumele zihlangabezane nezidingo zokubekezelela ukudlidliza ezindaweni ezeqisayo, ezinezindlela zokukhiya ezinentambo eziklanywe ngokukhethekile ezikwazi ukumelana nokushaqeka kwemishini okudlula i-10G.
Ngokuthuthukiswa kwezokuxhumana kwe-5G kanye nobuchwepheshe be-radar yezigaba ezinezigaba, izidingo zokusebenza kwesixhumi ziyaqhubeka nokukhuphuka. Isizukulwane esisha sezixhumi zebhendi ye-wave millimeter-sisebenzisa idizayini ye-dielectric yomoya-, inweba amaza okusebenza angaphezu kuka-67 GHz kuyilapho kugcinwa ukulahlekelwa kokufaka kungaphansi kuka-0.2 dB. Ngaphezu kwalokho, ithrendi ebheke ku-miniaturization ishayela ukusetshenziswa-kochungechunge lwesixhumi esincane esifana ne-SMP ne-BMA, ezincane ezingaphezu kuka-40% kunezinhlobo ze-SMA ezivamile, ezihlinzeka ngosekelo olubalulekile lokuhlanganiswa kwedivayisi.
"Njengebhuloho lesiginali" ezinhlelweni zikagesi, ukuvela kobuchwepheshe kwezixhumi ze-RF coaxial kuhlale kuhambisana nokuthuthukiswa kobuchwepheshe bezokuxhumana. Kusukela kumasistimu e-radar ezempi yokuqala kuya kumatheminali eselula e-5G anamuhla, lezi zingxenye ezinembayo ziyaqhubeka nokuqinisekisa ukudluliswa okuthembekile-kwamasignali amaza aphezulu, okuba usekelo oluyisisekelo olubalulekile lobuchwepheshe besimanje bolwazi lwe-elekthronikhi.
