Ukubaluleka kokupheliswa kokungafani kwe-Coaxial kwi-RF kunye ne-Microwave Engineering

Ukuphela kokungalingani kwe-coaxial yinxalenye ebalulekileyo kwicandelo le-RF kunye nobunjineli be-microwave. Isetyenziselwa ukufunxa isignali ebonakaliswa ngasemva ukusuka kukungalingani kwe-impedance kumgca wokudlulisela. Ngamazwi alula, xa kukho ukungafani phakathi kwe-impedance ephawulekayo yomgca wokudlulisela kunye ne-impedance yomthwalo, inxalenye yesignali ibonakaliswa ngasemva ukuya kumthombo. Esi signali sibonakalisiweyo sinokubangela ukuphazamiseka kwesignali, ukulahleka kwamandla, kunye neminye imiba kwinkqubo.

Ukuphela kokungalingani kwe-coaxial kwenzelwe ukufunxa esi signali sibonakalisiweyo nokunciphisa impembelelo yaso kwinkqubo. Ngokusisiseko kubonelela ngokuphela okufanelekileyo kumgca wothumelo, ukuqinisekisa ukuba yonke isignali ifunxwa ngokufanelekileyo kwaye akukho kukhanya kwenzekayo. Oku kunceda ukugcina ukuthembeka kwesignali kunye nokusebenza kakuhle kwenkqubo.

Kukho iintlobo ezahlukeneyo zokuphela kwe-coaxial mismatch ezikhoyo, kubandakanya ukupheliswa kwe-resistive, ukupheliswa kwe-reactive, kunye nokupheliswa kwe-complex impedance. Uhlobo ngalunye luneengenelo kunye nokusetyenziswa kwalo, kuxhomekeke kwiimfuno ezithile zenkqubo.

Ukuqukumbela, ukupheliswa kokungalingani kwe-coaxial yinxalenye ebalulekileyo kwiinkqubo ze-RF kunye ne-microwave ukuqinisekisa ukuthembeka kwesignali kunye nokusebenza kakuhle. Ngokufunxa ngokufanelekileyo isignali ebonakalisiweyo kwi-impedance mismatches, kunceda ukuphucula ukusebenza kwenkqubo kunye nokuthintela ukuphazamiseka kwesignali.
