Njengezingxenye ezibalulekile ekudluliselweni kwamasignali{0}emvamisa, izixhumi ze-RF coaxial zidlala indima engenakuthathelwa indawo{1}}ezimbonini ezinembayo ezifana nezokuxhumana, i-aerospace, test and measure, kanye ne-defence electronics. Izinzuzo zabo zobuchwepheshe zisukela ekwakhiweni kwabo okuhlukile kwesakhiwo nesayensi yezinto ezibonakalayo, okuholela ekuboniseni ubuqotho obukhethekile, ukuguquguquka kwemvelo, kanye{3}nokwethembeka kwesikhathi eside.
Ukusebenza kahle kokudluliswa kwesiginali kuyisici esiphawuleka kakhulu sezixhumi ze-RF coaxial. Ngokuxhumanisa okunembile kwesakhiwo se-coaxial (umqhubi wangaphakathi, ungqimba lwe-dielectric, umqhubi wangaphandle, nesihlangu), lezi zixhumi zicindezela ngempumelelo ukuphazamiseka kwe-electromagnetic (EMI) futhi zinciphise ukuncishiswa kwesignali. Isibonelo, kuzinhlelo zokusebenza-zemvamisa ephezulu ebangeni le-GHz,{3}}izixhumi zekhwalithi ephezulu ze-coaxial zingafinyelela isilinganiso se-voltage stand wave ratio (VSWR) ngaphansi kuka-1.2, okuqinisekisa ukuthi -ukudluliselwa kwesignali kwamahhala kuyakhanya. Lesi sici sibenza babe yinketho ekhethwayo yezinhlelo zokusebenza ezinzima njengeziteshi eziyisisekelo ze-5G, ezokuxhumana ngesathelayithi, nezinhlelo ze-radar.
Ukuzinza kwemishini nemvelo kuqhubekela phambili kuthuthukisa inani lesicelo sabo. Izixhumi zisebenzisa igolide- noma isiliva{2}}okuxhunyanwayo okupuletiwe, okuhlanganiswe nelokhi enentambo noma i-bayonet{3}}uhlobo lwesakhiwo somshini, ukuze imelane namashumi ezinkulungwane zemijikelezo yokukhwelana nokungalingani ngaphandle kokuphazamisa ukumelana nokuxhumana. Ngaphezu kwalokho, izindlu zivame ukwakhiwa ngensimbi engagqwali noma{5}}zepulasitiki yezinga lokushisa eliphezulu, esekela izinga lokushisa elibanzi lokusebenza elingu--55℃kuya ku-+165℃futhi enikeza umswakama nokungagqwali, ehlangabezana nezimfuneko zemishini yezempi ukuze isetshenziswe ezindaweni ezimbi kakhulu.
Ukuklama okujwayelekile kanye ne-modular kuthuthukisa kakhulu ukuhambisana kwesistimu. Amazinga wamazwe ngamazwe afana ne-SMA, BNC, kanye-nezicaciso zohlobo lwe-N{1}}ziqinisekisa ukuxhumana okungenazihibe phakathi kwemikhiqizo evela kubakhiqizi abahlukene, kunciphisa ukugcinwa kwezinto zokusebenza kanye nezindleko zokuthuthukisa. Ngaphezu kwalokho, iqhutshwa amathrendi e-miniaturization, izinhlobo zezixhumi ezinembayo ezifana no-1.0mm no-1.85mm ziyaqhubeka nokuvela, zihlinzeka ngosekelo lwesendlalelo esibonakalayo sokuthuthukiswa kobuchwepheshe begagasi be-millimeter{5}}.
Ngokuhamba kwesikhathi, izixhumi ze-RF coaxial nazo zinikeza ukuqina okuvelele kanye nokuvumelana nezimo kwezobuchwepheshe. Ngokuthuthuka kobuchwepheshe obufana-nokudluliswa kwedatha okushesha kakhulu kanye nama-antenna ahlelwe ngezigaba, izixhumi ezintsha ziyaqhubeka nokuthuthukisa ukufanisa i-impedance namandla okuphatha amapharamitha, afana ne-waveguide{2}}coaxial hybrid interfaces esekela ama-kilowatts ambalwa wamandla e-RF. Leli khono lokuhambisana nezikhathi liqinisekisa ukuthi zihlala ziyingxenye yesisekelo endaweni{4}}ephezulu yokuxhumanisa imvamisa.
Kafushane, izixhumi ze-RF coaxial zidlala indima ebalulekile njengamabhuloho esignali ezinhlelweni zesimanje zikagesi ngenxa yezinzuzo zazo ezintathu eziyinhloko: ukwethembeka kwesignali, ukubekezelela imvelo, nokwethembeka kwezobunjiniyela. Inani labo lobuchwepheshe lizoqhubeka nokujula ngokuthuthukiswa kwamazinga okuxhumana.
