Ukuqonda iimpawu ezisebenza rhoqo ze-coaxial connectors kubalulekile kwiinjineli ekukhetheni isinxibelelanisi esifanelekileyo. Eli nqaku liza kuphonononga kwingqikelelo yokusebenza rhoqo kwiziqhagamshelo zeRF coaxial kwaye linike ingcaciso eneenkcukacha yeempawu zefrikhwensi kunye nokusetyenziswa kwemizi-mveliso yeziqhagamshelo ezahlukeneyo.
Yintoni i-frequency yokusebenza kwe-coaxial connector?
Amaxesha asezantsi okunqunyulwa kwe-RF coaxial connector ngu-zero, kwaye i-frequency yokusebenza ephezulu idla ngokuba yi-95% ye-cutoff frequency.
I-frequency yokusebenza ixhomekeke kwisakhiwo sokudibanisa. Uluhlu oluphindaphindiweyo lwaso nasiphi na isinxibelelanisi sikhawulelwe yimowudi yokuqala ejikelezayo ye-waveguide ebonakala kwisakhiwo se-coaxial. Ukunciphisa ubungakanani bekhebula kunokunyusa i-cutoff frequency ye-connector, ngelixa ukuzaliswa kwezinto ze-dielectric kuya kunciphisa i-frequency yokusebenza kunye nokunyusa ilahleko.
Ngoko ke, ukuthetha ngokubanzi, ubungakanani obuncinci be-conductor yangaphandle, iphezulu i-frequency yokusebenza ye-connector; i-dielectric constant constant ye-medium filling, iphezulu i-frequency yokusebenza kunye nelahleko ephantsi yokufaka.
Zeziphi izinto ezichaphazela ukusebenza rhoqo?
Ubuninzi bokusebenza bubhekisa kuluhlu lwamaza apho isidibaniso seRF coaxial sinokuzinza kwaye sisasaze iisignali ngokufanelekileyo. Ayinakugqiba kuphela izicelo zemizi-mveliso apho isinxibelelanisi sifanelekile kodwa ikwachaphazela ngokuthe ngqo umgangatho wokuhanjiswa komqondiso, ilahleko, kunye nokuzinza kwenkqubo.
I-frequency yokusebenza inqunywe yile miba ilandelayo: uyilo lwesakhiwo somzimba wekhonkco (ezifana nobukhulu, izinto ze-dielectric), iiparamitha zokusebenza kombane (i-VSWR, ilahleko yokufaka, njl.), inkqubo yokuvelisa kunye nokuchaneka, njl.
Kwizicelo zemizi-mveliso, ukusebenza rhoqo yeyona nto iphambili yokuqwalaselwa xa ukhetha isinxibelelanisi. Uluhlu lwefrikhwensi emxinwa lunokukhokelela ekusebenzeni okulinganiselweyo kwenkqubo, ngelixa i-frequency ephezulu kakhulu inokubangela ukubonakaliswa komqondiso kunye nelahleko eyandileyo.
