I-Waveguide Fixed Attenuators RF Microwave Millimeter Wave mm wave
I-Waveguide Fixed Attenuators iyisisetshenziswa esingenzi lutho esisetshenziswa kabanzi emkhakheni wobuchwepheshe be-microwave.
Iklanyelwe ukunciphisa amasiginali we-microwave adluliselwa kuma-waveguides ngesilinganiso esinqunyiwe. Isibonelo, lapho isignali ye-microwave idlula ku-attenuator egxilile ye-waveguide, ingxenye yamandla iyamuncwa noma ilahleke, ngaleyo ndlela kunciphisa amandla esignali yokuphumayo.
I-Waveguide wuhlobo lwesakhiwo se-waveguide esisetshenziselwa ukudlulisa ama-microwave. I-waveguide fixed attenuator isuselwe esakhiweni se-waveguide futhi ifinyelela inani eligxilile lokuncishiswa ngezinto ezikhethekile noma idizayini yesakhiwo. Ivamise ukusebenzisa izinto eziphikisayo noma izakhiwo ezikhethekile zikagesi ukuze imunce amandla e-microwave.
Inhloso:
1. Ukunakwa Kwesiginali: Izibambisi ze-RF zisetshenziselwa ukunciphisa ngokunembile amandla amasiginali e-RF nama-microwave ukuze kuvikelwe amathuluzi okwamukela azwelayo kanye namazinga esignali okulawula.
2. Ukufanisa Amandla: Izibambisi ze-Microwave zingasetshenziswa ukufanisa izinga lamandla esistimu, ngaleyo ndlela kuncishiswe ukubonakaliswa namagagasi amile futhi kuthuthukiswe ukusebenza kwesistimu.
3. Ukulinganiswa Kwesistimu: Izibambisi zamagagasi eziyimilimitha zisetshenziselwa ukulinganisa nokuhlola amasistimu e-RF nama-microwave ukuze kuqinisekiswe ukusebenza okuzinzile kwesistimu kumazinga ahlukene wamandla.
Isicelo:
1. Isistimu ye-radar: Ezinhlelweni ze-radar, i-attenuators ye-waveguide isetshenziselwa ukulungisa nokulawula ukuqina kwamasignali adlulisiwe nawamukelwe. Lokhu kusiza ukuthuthukisa amandla okuthola nokunemba kwamasistimu e-radar.
2. Ukuxhumana Ngesathelayithi: Ezinhlelweni zokuxhumana ngesathelayithi, izibambisi ezigxilile zisetshenziselwa ukulungisa amandla esignali ukuze kuqinisekiswe ukwethembeka nokuzinza kwesixhumanisi sokuxhumana. Angasetshenziselwa ukudlulisa isignali phakathi kweziteshi ezingaphansi namasathelayithi.
3. Ukuxhumana Kwe-Microwave: Ezinhlelweni zokuxhumana ze-microwave, izinciphisi ze-microwave zisetshenziselwa ukulungisa nokulawula amandla esignali ukuze kuthuthukiswe ukusebenza nokuthembeka kwezixhumanisi zokuxhumana.
4. Ukuhlolwa Nesikali: Kuhlelo lwe-RF kanye ne-microwave yokuhlola neyokulinganisa, ama-millimeter wave attenuators asetshenziselwa ukulawula ngokunembile amandla esignali okuhlola nokulinganisa okuhlukahlukene. Lokhu kubalulekile ukuze uqinisekise ukusebenza kwemishini namasistimu akho.
5. Umsakazo kanye neThelevishini: Ezinhlelweni zomsakazo nethelevishini, ama-mm wave attenuators asetshenziselwa ukulungisa amandla esignali futhi athuthukise ikhwalithi yesignali nokumboza. Lokhu kusiza ukunikeza amasignali acacile omsindo nevidiyo.
6. Ucwaningo Lwesayensi: Kumaphrojekthi ocwaningo lwesayensi, i-waveguide fixed attenuators isetshenziselwa ukulawula nokulawula i-RF kanye namandla esignali ye-microwave ekuhlolweni. Lezi zifundo zingabandakanya isayensi yezinkanyezi, i-physics, neminye imikhakha.
Qualwaveihlinzeka nge-VSWR ephansi kanye nokuqina okuphezulu kwe-flatness kusuka ku-3.94 kuya ku-500GHz. Ububanzi bokunciphisa bungu-0~40dB.
