Ikhebula le-RFikhebula elikhethekile elisetshenziselwa ukudlulisa amasignali efrikhwensi yomsakazo.Ivamise ukusetshenziselwa ukuxhuma imishini yomsakazo nezimpondo ukuze udlulise futhi wamukele amasignali omsakazo.Intambo yesiginali ye-RF inokuvikela okuhle kakhulu nezici zokulahlekelwa okuphansi, futhi ingadlulisela ngempumelelo amasignali amaza aphezulu, ngakho isetshenziswa kabanzi emkhakheni wokuxhumana okungenantambo kanye nemishini kagesi.
Izintambo zesiginali ye-RF ziklanywa futhi zenziwa ngokunemba okukhulu ukuze kuqinisekiswe ukuthi ukuncishiswa kwesignali nokuphazamiseka kuyancishiswa ngesikhathi sokudlulisela.Ivamise ukwakhiwa nge-conductor yangaphakathi, i-insulating layer, i-conductor yangaphandle kanye ne-sheath yangaphandle.I-conductor yangaphakathi, ngokuvamile eyenziwe ngethusi noma i-aluminium, isetshenziselwa ukudlulisa amasignali;Isendlalelo se-insulation sisetshenziselwa ukuhlukanisa ama-conductor angaphakathi nangaphandle ukuvimbela ukuphazamiseka nokulahlekelwa kwesignali;I-conductor yangaphandle isetshenziselwa ukuvikela amasignali angaphakathi nokunciphisa ukuphazamiseka kwangaphandle;I-sheath yangaphandle isetshenziselwa ukuvikela yonke ikhebula endaweni yangaphandle.
Ukukhethwa kwentambo yesiginali ye-RF kuncike ebangeni lefrikhwensi oyifunayo, ibanga lokudlulisela, izimo zemvelo kanye nezidingo zohlelo.Izinhlobo ezijwayelekile zezintambo zesiginali ye-RF zifaka izintambo ezingamakhoaxial, imigqa ye-microstrip, nemigqa ebhalansi.Intambo ye-coaxial iwuhlobo olusetshenziswa kakhulu, olufanele ukudluliswa kwesignali yebanga elide kanye nobubanzi befrikhwensi ephezulu.Imigqa ye-Microstrip ifanele ukudluliswa kwamasiginali we-microwave we-high-frequency, kuyilapho imigqa ebhalansi ifanele izidingo ezithile zokudlulisa isignali ezilinganiselwe.
Emkhakheni wokuxhumana okungenantambo, izintambo zesiginali ye-RF zisetshenziswa kakhulu eziteshini eziyisisekelo zokuxhumana eziphathwayo, izinhlelo zokuxhumana ngesathelayithi, amasistimu e-radar namathuluzi okuhlonza amafrikhwensi omsakazo.Badlala indima ebalulekile kulezi zinhlelo zokusebenza, ukuqinisekisa ukudluliswa okuzinzile nokwamukela amasignali.Ngaphezu kwalokho, emkhakheni wemishini kagesi, izintambo zesiginali ye-RF nazo zisetshenziselwa ukuxhuma amadivaysi e-RF ahlukahlukene, izinti namamodemu, njll., ukunikeza ukwesekwa okuthembekile kokudluliswa kwesignali phakathi kwamadivayisi.
Ngokuvamile, izintambo zesignali ze-RF ziyingxenye ebalulekile futhi ebalulekile emkhakheni wezokuxhumana okungenantambo kanye nemishini kagesi.Banikeza ukwesekwa okubalulekile kokusebenza okufanele kwezinhlelo zokusebenza ezihlukahlukene ezingenazintambo kanye nemishini kagesi ngokunikeza ukudluliswa kwesignali okuzinzile nokwamukela.Ngokuthuthuka okuqhubekayo kokuxhumana okungenantambo kanye nobuchwepheshe be-elekthronikhi, isidingo samakhebula esignali e-RF sizoqhubeka sikhula, kulethe ukusungulwa okwengeziwe namathuba entuthuko embonini.
