Iziqhagamshelo zeRF coaxial ngamalungu aphambili okusasaza-imiqondiso yefrikhwensi kwaye zisetyenziswa kakhulu kunxibelelwano, irada, i-aerospace, kunye neminye imimandla. Umsebenzi wabo ongundoqo kukubonelela ngoqhagamshelwano oluthembekileyo phakathi kwezixhobo ngelixa uqinisekisa ukunyaniseka kwesignali.
Ulwakhiwo olusisiseko lwe-RF coaxial connector lubandakanya i-coaxial conductor yangaphakathi, i-conductor yangaphandle (idla ngokuba yikhaka), kunye ne-dielectric ekhuselayo phakathi kwazo. I-conductor yangaphakathi igqithisa -i-frequency current ephezulu, ngelixa i-conductor yangaphandle ibonelela ngekhuselo lomhlaba, ikhusela umqondiso kuphazamiseko lwangaphandle lwe-electromagnetic. I-dielectric ye-insulating, ephakathi kwabaqhubi bangaphakathi nangaphandle, igcina ukuhlukaniswa kombane kwaye ixhasa umqhubi wangaphakathi. Olu lwakhiwo luvumela ilahleko esezantsi{4}}kunye{5}}nozinzo oluphezulu losasazo lweempawu zeRF.
Umgaqo wokusebenza usekwe kwiimpawu zokusasaza zamaza e-electromagnetic kwisakhiwo se-coaxial. Xa umqondiso ophezulu-we-frequency udlula kwi-conductor yangaphakathi, isiphumo sokukhusela somqhubi wangaphandle sithintela intsimi ye-electromagnetic kwisithuba esiphakathi kwee-conductor zangaphakathi nangaphandle, zenza i-TEM ezinzileyo (i-transverse electromagnetic) iphethini yamaza. Le pateni iqinisekisa ngemitha ephantsi kunye{3}}nelahleko ephantsi yosasazo lwesignali. Uyilo lwesiqhagamshelo kufuneka lufaniswe ngokuchanekileyo ukuze kuqinisekiswe ukuqhubeka phakathi kwabaqhubi bangaphakathi nangaphandle ukuphepha ukubonakalisa umqondiso okanye ukulahlekelwa kwamandla ngenxa yokungahambi kakuhle kwe-impedance.
Isitshixo ekusebenzeni kweziqhagamshelo ze-coaxial ze-RF silele kungqamaniso lwazo lwe-impedance, ngokuqhelekileyo i-50Ω okanye i-75Ω ukulungiselela iimfuno ezahlukeneyo zesicelo. Ukungahambelani kwe-impedance kunokukhokelela ekubonakalisweni komqondiso, ukunciphisa ukusebenza kakuhle kokuhanjiswa, kunye nomonakalo kwizixhobo. Ke ngoko, ijiyometri yesiqhagamshelo, ukhetho lwemathiriyeli, kunye nokuchaneka komatshini kuphuculwe ngokungqongqo ukuqinisekisa ukutshintshwa okugudileyo komgangatho ophezulu{4}}wemiqondiso yokuphindaphinda kwindawo yoqhagamshelo.
Ngaphaya koko, iziqhagamshelo zeRF coaxial kufuneka zibonise uzinzo olugqwesileyo lomatshini kunye nokuguquguquka kokusingqongileyo, njengokuchasana nobushushu obuphezulu, ukufuma, kunye nokungcangcazela, ukuhlangabezana neemfuno zeemeko zokusebenza ezinzima. Ngokufutshane, iziqhagamshelo zeRF coaxial, ngoyilo oluphucukileyo lwe-electromagnetic kunye noyilo lomatshini, ziphumeza usasazo olusebenzayo noluzinzileyo lwemiqondiso yefrikhwensi ephezulu, ezenza zibe yinxalenye eyimfuneko kwiinkqubo zale mihla zombane.
