Lihokelo tsa RF coaxial, e le likarolo tsa bohlokoa bakeng sa -ho fetisoa ha maqhubu a phahameng, li bapala karolo ea bohlokoa likhokahanong, sepakapaka, tekong le ho methang, le mafapheng a mang. Moralo oa bona o tlameha ho fihlela litlhokahalo tsa tahlehelo e tlase, botsitso bo phahameng, le khokahanyo e tšepahalang bakeng sa -mats'oao a khafetsa, a hlahisang letoto la likarolo tse ikhethang tsa tekheniki.
Taba ea pele, lihokelo tsa RF coaxial li fana ka tšebetso e ntle haholo-ea phetisetso ea khafetsa. Sebopeho sa bona se sebelisa sebopeho sa coaxial se nang le conductor ea ka hare, dielectric e sireletsang, le conductor ea ka ntle. Sena se tiisa hore lebala la motlakase le tsepamisitsoe ka har'a dielectric lipakeng tsa li-conductor tsa kahare le kantle, ka hona ho fokotsa mahlaseli a mats'oao le tšitiso ea kantle. Ka ho ntlafatsa mokhoa oa ho tsamaisana (joalo ka 50Ω kapa 75Ω), likhokahano tsa RF coaxial li fokotsa likhantši le ho netefatsa phetisetso e nepahetseng ea -ea maqhubu a holimo (ho tloha MHz ho ea GHz esita le ho feta).
Ea bobeli, tšireletso e babatsehang le tahlehelo e tlaase ke tse ling tsa melemo ea tsona ea mantlha. Conductor ea kantle hangata e entsoe ka thepa e tsamaisang haholo joalo ka alloy ea koporo kapa tšepe e sa hloekang, 'me plating (joalo ka khauta kapa nickel) e ntlafatsa ho hanyetsa oxidation le ho ts'epahala ha likhokahanyo. Sebopeho sena se sireletsa ka katleho sehokelo ho tsoa ho tšitiso ea motlakase ea kantle (EMI), ha khetho ea thepa e sireletsang (joalo ka polytetrafluoroethylene (PTFE) kapa ceramic) e fokotsa ho fokotseha ha matšoao, ho netefatsa botšepehi le botsitso ba matšoao a fetisoang.
Ho feta moo, lihokelo tsa RF coaxial li fana ka likhokahano tse tšepahalang tsa mochini le ho tšoarella. Meetso ea li-interface (joalo ka threaded, bayonet, kapa push-pull) e netefatsa khokahanyo e sireletsehileng le maemong a thata joalo ka ho thothomela le ho ts'oha, ho thibela ho sitisoa ha lets'oao ka lebaka la ho hlepha. Ho feta moo, -lisebelisoa tsa boleng bo holimo (tse kang beryllium copper le stainless steel) le machining a nepahetseng li li thusa ho mamella ho pola khafetsa le ho khaoha ntle le ho senya ts'ebetso ea motlakase, ho etsa hore li tšoanelehe{4}}tšebeliso ea nako e telele indastering.
Qetellong, lihokelo tsa RF coaxial li fana ka mefuta e fapaneng ea mefuta le likarolo tse emeng. Ho ipapisitsoe le litlhoko tsa ts'ebeliso, mefuta e fapaneng (joalo ka SMA, BNC, N-mofuta, le TNC) e shebana le boholo, sebaka sa maqhubu, le matla a ho sebetsana le matla. Li latela maemo a machaba (joalo ka IEC le MIL-STD) ho netefatsa hore lia sebeletsana le ho fapanyetsana lisebelisoa tse fapaneng.
Ka bokhuts'oanyane, likhokahano tsa RF coaxial li fetohile karolo ea bohlokoahali lits'ebetsong tsa sejoale-joale tsa elektroniki ka lebaka la ts'ebetso ea tsona e phahameng-ea phetiso ea khafetsa, ts'ireletso e ntle haholo, sebopeho se tšepahalang sa mochini le moralo o tloaelehileng, 'me li tsoela pele ho khothaletsa nts'etsopele ea likhokahano le theknoloji ea elektroniki.
