Ukuqonda ukubaluleka kokupheliswa kwe-ceaxial - imithwalo yedummy kwiinkqubo ze-RF

Ukupheliswa kwe-coaxial, okwaziwa ngokuba ngumthwalo wedumm, sisixhobo esisetyenziswe kubunjineli be-Elektroniki ukulinganisa umthwalo wombane ngaphandle kokusasaza amandla. Inendawo exhaphakileyo efakwe kwisiciko sensimbi exhunyiwe kwi-quaxial cable yomsebenzi. Injongo yokupheliswa kwesimilo se-coaxial kukufumana amandla erediyo radio (RF) kwaye uthintele ekubonakaliseni ukubuyela kwisekethe.

Imithwalo yeDummy iqhele ukusetyenziswa kwizicelo ezahlukeneyo, njengokuvavanywa kunye nokulinganiswa kwerediyo Ngokubonelela ngomdlalo oqingqiweyo wokufumana isixhobo phantsi kovavanyo, umthwalo wedumm uqinisekisa ukuba amandla e-RF acelwe kwaye akabangeli uphazamiseko okanye ukonakaliswa kwezixhobo. Oku kubaluleke ngakumbi ngexesha lesigaba sokuvavanywa kwezixhobo ze-elektroniki ukuthintela imiqondiso enokuchaphazela ukuchaneka kwemilinganiselo.

Ukongeza kuvavanyo kunye nokulinganisa, ukupheliswa kwe-ceaxial kukwasetyenziswa kwi-RF kunye neenkqubo ze-microwave ukuphelisa imigca yothumelo engasetyenziswanga, ukuthintela ingqibelelo yomqondiso. Kwizicelo ezinde ezinenziwe rhoqo, ezifana neendlela zefowuni kunye neenkqubo ze-radar, ukusetyenziswa kwemithwalo yedumm kunceda ekunciphiseni ilahleko yomqondiso kunye nokuqinisekisa ukuhanjiswa okusebenzayo kwe-RF.

Uyilo lokupheliswa kwesimilo se-coaxial kubalulekile ekusebenzeni kwayo, ngezinto ezinjengokuhambelana nokuhambelana, ukuphatha amandla okuphatha, kunye noluhlu lokudlala oludlala indima esebenzayo ekusebenzeni kwayo. Iindidi ezahlukeneyo zokupheliswa kwezinto ezimiselweyo ze-coaxial ziyafumaneka, kubandakanya imithwalo engahambelaniyo nezingasebenziyo, nganye ilungele izicelo ezithile ezisekwe kwiimpawu zazo zombane.

Ukuqukumbela, ukupheliswa kwe-coaxial okanye imithwalo ye-dummy zizinto ezibalulekileyo kwi-RF kunye neenkqubo zeMicrowave, zibonelela ngeendlela ezinokuthenjwa, ezibonelela ngeendlela ezinokuthenjwa kwaye zine-rf amandla. Ngokusebenzisa imithwalo yedummy kuvavanyo kunye neenkqubo zokulinganisa, iinjineli zinokuqinisekisa ukuchaneka kunye nokusebenza kakuhle kwezixhobo ze-elektroniki, ekugqibeleni zikhokelela kwinkqubo ephuculweyo kunye nokuthembeka kwiinkqubo ze-elektroniki.
