Ukuphela kwe-RF Microwave Load okungu-75 Ohms
Ukuphela kwe-75 ohm
Umthwalo we-75 ohm uwukuphela okuvamile kokumelana okusetshenziselwa kakhulu ukuhlola nokulinganisa imishini efana namajeneretha esignali, ama-amplifier kagesi, izinhlelo ze-RF, amathelevishini, njll. kumasekethe.
Ukuphela kwe-microwave kunezici ezilandelayo:
1.A Ukuqedwa kwe-75 ohm kunciphisa ukubonakaliswa nokulahlekelwa kwesignali, kuthuthukisa ukudluliswa kwesignali, ngaleyo ndlela kuthuthukisa ukuzinza kwesistimu nokuthembeka.
2. I-RF Termination iyi-standard Termination impedance esetshenziswa kabanzi embonini yezokuxhumana, ehlangabezana nezindinganiso ze-Federal Telecommunications Laboratory (NIST) futhi kulula ukuyisebenzisa emsebenzini ongokoqobo.
3. Ngesikhathi senqubo yokulinganisa nokuhlola, ukuqedwa kwe-75 ohm kungavikela imishini yomthombo ekulimaleni kwe-overvoltage noma kwe-overcurrent, okuqinisekisa ukuphepha kwemishini yokuhlola kanye nemishini evivinyiwe.
4. Ukuphela kwe-75 ohm kungasekela amandla aphezulu okukhipha futhi kungasetshenziswa ezinhlelweni ze-RF ezidinga amandla aphezulu.
5. Ukuqedwa kwe-75 ohm kunganikeza ukuvinjelwa kokuqeda okunembe kakhulu kokulinganisa okunembile kwamapharamitha wesici sesekethe, okwenza imiphumela yokuhlola inembe futhi ithembeke kakhudlwana.
Inemisebenzi elandelayo:
1.Ukuphela kwe-75 ohm kungasetshenziswa ukuhlola amandla okukhipha, izici zokuphendula imvamisa, kanye nokuqinisekisa ukusebenza okuphelele kwesekethe.
2.Ukuphela kwe-75 ohm kungasetshenziswa ukufanisa ukuvimba kwamagagasi, ukunciphisa ukubonakaliswa nokulahlekelwa yisignali, ukwenza ngcono ukudluliswa kwesignali, nokuthuthukisa ukuzinza nokuthembeka kwesistimu.
3.Ukuphela kwe-75 ohm kungasebenza njengechweba lokukhipha isignali labakhiqizi besignali kanye nama-amplifier wamandla, okwenza ukuthi amasignali akhishwe kwezinye izingxenye zesistimu ngezinjongo zokuhlola nokulinganisa.
4.Ukuphela kwe-75 ohm kungavikela ezinye izingxenye zesekethe ekuphepheni ngokweqile nasekuphelelweni ngokweqile, kunciphisa ingozi yokulimala kwemishini kanye nokungasebenzi kahle.
I-Qualwaveihlinzeka ngokunemba okuphezulu kanye namandla aphezulu e-coaxial angu-75 Ohms. Ukuphela kwemvamisa kuhlanganisa ububanzi bemvamisa ye-DC ~ 3GHz. Ukuphela kwemvamisa kunezinhlobo ezahlukene zokuhlangabezana nezidingo zamakhasimende.
