Intambo ye-RF, njengomthombo ophambili wosasazo{0}}losasazo lwamaxesha amaninzi, inefuthe elithe ngqo kuzinzo nokuthembeka kweenkqubo zonxibelelwano. Indlela yayo yokuhlanganisa ibandakanya ulungelelwaniso olulungelelanisiweyo lwesayensi yezinto, ithiyori ye-electromagnetic field, kunye neenkqubo zokwenziwa ezichanekileyo, ezifuna uhlalutyo lwamacandelo amane angundoqo: i-conductor, umaleko wokugquma, umaleko okhuselayo, kunye ne-sheath.
Ikhondaktha sisiseko seentambo zeRF kwaye ngokuqhelekileyo zenziwe{0}ngobhedu olusulungekileyo oluphezulu (olufana neoksijini{1}lobhedu olusimahla) okanye isilivere{2}}icingo lobhedu oluphothiweyo ukuqinisekisa ukuxhathisa okuphantsi kunye nokuqhuba okugqwesileyo. -Iiconductors eziqinileyo zomtya zilungele{5}}usetyenziso oluchanekileyo, ngelixa iiconductors ezixineneyo zibonelela ngobhetyebhetye olukhulu kwaye zihlala zisetyenziswa kwiimeko zeentambo eziguqukayo. Idayamitha ye-conductor kunye nokugqiba komphezulu kufuneka zihambelane ngokungqongqo noluhlu lwamaza okujoliswe kuko ukunqanda ukuthotywa komqondiso okubangelwa sisiphumo solusu.
Uyilo lwe-insulation luchaphazela ngokuthe ngqo i-impedance ye-cable kunye nelahleko ye-dielectric. Izinto eziqhelekileyo ziquka i-polyethylene (PE), i-polytetrafluoroethylene (PTFE), kunye ne-foam dielectrics. Ukufakwa kwe-PE okuqinileyo kunika ixabiso eliphantsi kunye namandla aphezulu omatshini, kodwa kukwane-dielectric rhoqo. I-PTFE, ngenxa yelahleko ephantsi, lolona khetho lukhethwayo kusetyenziso lwamaxesha amaninzi-, ngelixa izakhiwo ezinogwebu zisehlisa ngakumbi ilahleko yothumelo lomqondiso ngokunciphisa ingxinano yedielectric. Ubukhulu bomaleko wokugquma kufuneka bubalwe ngokuchanekileyo ngokusekelwe kwifomula ye-impedance yempawu (efana ne-50Ω okanye i-75Ω esemgangathweni) ukuqinisekisa ukusasazwa okufanayo kwamaza ombane wombane phakathi komqhubi kunye nekhaka.
Umaleko okhuselayo ngowona mqobo wokucinezela ukuphazamiseka kwe-electromagnetic interference (EMI) kwaye yenziwe ngentsimbi ephothiweyo, ifoyile yealuminiyam, okanye indibaniselwano yezi zimbini. Kabini-ukhuselo lomaleko (olufana nefoyile yealuminiyam + umluko) kunokunyusa ukusebenza kokhuselo ukuya ngaphezulu kwe-80dB kwaye ilungele usetyenziso olubango olufana nezixhobo zonyango kunye ne-aerospace. Uxinaniso lwe-braid olungaphaya kwe-90% luthintela ngokufanelekileyo ingxolo yangaphandle, ngelixa umaleko wefoyile ye-aluminiyam ibonelela ngokhuseleko olongezelelweyo lweradial ngokuchasene nophazamiseko oluphezulu{6}}
Izinto zejacket kufuneka zilungelelanise ukuhambelana kokusingqongileyo kunye nokukhuselwa komatshini. Idangatye-i-PVC eretardant ilungele imeko-bume zemizi-mveliso ngokubanzi, ngelixa i-polyurethane (TPU) okanye i-fluoroplastics igqwesa kwizicelo ezikhethekileyo ezifana -nobushushu obuphezulu kunye ne-oyile{3}}ukuxhathisa umhlwa. Ukuxhathisa kwebhatyi ye-abrasion kunye nokumelana ne-UV kuchaphazela ngokuthe ngqo ubomi benkonzo yentambo.
Ngamafutshane, indlela yokwakheka kweentambo zeRF kufuneka zifikelele kwibhalansi phakathi kokusebenza, ukugquma, ukusebenza kakuhle kokukhusela kunye nokuqhelana nemo engqongileyo ngoyilo lwentsebenziswano yezinto ezininzi kunye nolawulo lwenkqubo oluchanekileyo, kwaye ekugqibeleni luhlangabezene{1}}iimfuno zothumelo lwamaxesha amaninzi ukusuka kwizitishi ezisisiseko zonxibelelwano ukuya kumakhonkco esathelayithi.
