I-RF High Power BroadBand Test Systems 75 ohms Attenuators
I-75 ohm attenuator iwuhlobo lwesinqamuleli esiqanjwe ngokuphazamiseka kwayo okungama-75 ohms.
Iyingxenye yokungenzi lutho esetshenziselwa ukulawula amandla esiginali yesekhethi, i-Attenuator engu-75 ohm ivimbela ukukhulisa nokuphazamiseka kwesignali, futhi ivimbela ukwehluleka okubangelwa ukugcwala kwesignali.
Izici zayo eziyinhloko zihlanganisa:
1. Ukumatanisa kokuphazamiseka: I-impedance yesici engu-75 ohm ifana nokuthikamezeka kwesici kolayini wokudlulisa isignali wemishini yevidiyo, ukusakazwa komabonakude kanye nesistimu kamabonakude wekhebula, ngaleyo ndlela kunciphisa ukubonakaliswa nokulahlekelwa kwesignali yokudlulisela.
2. Ukuhlanekezela okuphansi: I-attenuator inganciphisa amandla esignali ngaphandle kokwethula ukuhlanekezela okwengeziwe noma ukuphazamiseka kwesignali.
3. Ukuthembeka okuphezulu: Ngenxa yokuthi ama-attenuators ayizingxenye ezingenzi lutho futhi azinazo izingxenye ezihambayo, zithembeke kakhulu futhi azidingi ukulungiswa noma ukushintshwa.
Ama-75 ohm attenuators avame ukusetshenziswa kulezi zinhlelo zokusebenza ezilandelayo:
1. Kumanethiwekhi kamabonakude ekhebula kanye namanethiwekhi kamabonakude edijithali, isetshenziselwa ukulawula amandla esignali nokunciphisa ukubonakaliswa kwesignali nokulahlekelwa.
2. Ngesikhathi sokukhiqiza nokudluliswa kwamavidiyo anokulungiswa okuphezulu kanye nencazelo ephezulu, lawula amandla esignali futhi ugcine ikhwalithi yokuguqulwa.
3. Ezinhlelweni zokusakaza namasiginali kamabonakude, okokusebenza okulungisa amandla esiginali ukuze kufane nokucubungula isignali ethile esabalalisiwe kanye nokwandisa ububanzi besiginali.
4. Ezintini zikamabonakude, ezisetshenziselwa ukulinganisa amandla esiginali phakathi kwezikhulisi nezinti.
Qualwaveinikeza ukunemba okuphezulu okuhlukahlukene namandla aphezulu ama-coaxial 75 ohms attenuators amboza ibanga lemvamisa ye-DC~3GHz, angafaniswa nezixhumi ze-BNC, zohlobo lwe-F, nezixhumi zohlobo lwe-N. I-attenuation isukela ku-1 kuye ku-40dB. Ama-attenuators anokunemba Okuphezulu namandla aphezulu, ikhwalithi ethembekile, imikhiqizo eminingi ithobela i-ROHS, ingahlangabezana nezidingo ezihlukene zamakhasimende.
