Intshayelelo yeCable yeRF
Ukongeza kuluhlu lwamaza, umlinganiselo wokuma wamaza, ilahleko yokufaka kunye nezinye izinto, ukhetho oluchanekileyo lwamacandelo entambo ye-RF kufuneka kwakhona luthathele ingqalelo iimpawu zomatshini wentambo, indawo yokusebenza kunye neemfuno zesicelo, ukongeza, iindleko zikwayinto ehlala itshintsha. .
Kweli phepha, izalathisi ezahlukeneyo kunye nokusebenza kwentambo ye-RF zixoxwa ngokweenkcukacha.Kuluncedo kakhulu ukwazi ukusebenza kwentambo ekukhetheni eyona ndibano ilungileyo ye-RF cable.
Ukukhetha ikhebula
Intambo ye-coaxial ye-RF isetyenziselwa ukusasaza amandla e-RF kunye ne-microwave.Yisekethe yeparameter esasaziweyo ubude bayo bombane bungumsebenzi wobude bomzimba kunye nesantya sothumelo, esahluke kakhulu kwisekethe ephantsi.
Iintambo ze-coaxial ze-RF zinokwahlulwa zibe ziingcingo ezizii-semi-rigid kunye ne-semi-flexible, iintambo eziguquguqukayo eziphothiweyo, kunye neentambo ezinogwebu ngokwasemzimbeni.Iindidi ezahlukeneyo zeentambo kufuneka zikhethwe kwizicelo ezahlukeneyo.Iintambo ezingagungqiyo kunye ne-semi-flexible zisetyenziswa ngokubanzi kuqhagamshelo kwisixhobo;Kwintsimi yokuvavanya kunye nokulinganisa, iintambo eziguquguqukayo kufuneka zisetyenziswe;Iintambo ezinogwebu zihlala zisetyenziswa kwiinkqubo zesiseko se-eriyali yesitishi.
Intambo eqinileyo
Njengoko igama libonisa, olu hlobo lwentambo alugobeki lula ukuba lumile.I-conductor yangaphandle yenziwe nge-aluminium okanye ityhubhu yobhedu.Ukuvuza kweRF kuncinci kakhulu (ngaphantsi kwe -120dB) kwaye intetho edibeneyo ebangelwa kwinkqubo ayinanto.
Uphawu lwe-passive intermodulation lwale ntambo lukwafanelekile kakhulu.Ukuba ufuna ukugoba kwimilo ethile, udinga umatshini okhethekileyo wokubumba okanye i-mold manual yokwenza.Itheknoloji yokucubungula inkathazo enjalo ekubuyiseleni ukusebenza okuzinzileyo, ikhebula le-semi-rigid usebenzisa i-polytetrafluoroethylene eqinile njengento yokuzalisa, le nto ineempawu zokushisa ezizinzileyo kakhulu, ngakumbi phantsi kweemeko eziphezulu zokushisa, zinezinga elihle kakhulu lokuzinza.
Iintambo ezingaqini-lukhuni zibiza ngaphezulu kweentambo ezithambileyo kwaye zisetyenziswa ngokubanzi kwiinkqubo ezahlukeneyo zeRF kunye ne-microwave.
Intambo ephothiweyo ethambileyo
Intambo ethambileyo yintambo “yebakala lovavanyo”.Xa kuthelekiswa ne-semi-rigid kunye ne-semi-flexible cables, ixabiso leentambo eziguquguqukayo libiza kakhulu, kuba iintambo eziguquguqukayo zenzelwe ukuqwalasela izinto ezininzi.Intambo eguquguqukayo kufuneka ibe lula ukugoba amaxesha amaninzi kwaye igcine ukusebenza, eyona mfuneko isisiseko njengentambo yovavanyo.Iimpawu zombane ezithambileyo nezilungileyo zimbini eziphikisanayo, kodwa zikhokelela kwiindleko zesizathu esikhulu.
Ukukhethwa kwamacandelo entambo ye-RF ebhetyebhetye kufuneka kuthathelwe ingqalelo izinto ezahlukeneyo ngaxeshanye, kwaye ezinye zezi zinto ziyaphikisana, umzekelo, intambo ye-coaxial ene-coaxial cable ene-single-strand yangaphakathi inelahleko esezantsi yokufaka kunye nozinzo lwe-amplitude xa igoba kune-multi-strand coaxial cable. , kodwa ukusebenza kozinzo lwesigaba akulunganga njengokugqibela.Ke ngoko, ukukhethwa kwecandelo lekhebula, ukongeza kuluhlu lwamaza, umlinganiselo wokuma wamaza, ukulahleka kokufakwa kunye nezinye izinto, kufuneka kwakhona kuqwalaselwe iimpawu zomatshini wentambo, indawo yokusebenza kunye neemfuno zesicelo, ukongezelela, ixabiso likwayinto engaguqukiyo. into.
