2.92mm isixhumi se-coaxial wuhlobo olusha lwesixhumi se-millimeter wave coaxial esinobubanzi bangaphakathi bekhondatha yangaphandle engu-2.92mm kanye nokuvinjelwa kwesici okungu-50 Ω.Lolu chungechunge lwezixhumi ze-RF coaxial lwakhiwe nguWiltron.Onjiniyela bakudala ngo-1983 bathuthukise uhlobo olusha lwesixhumi esisekelwe kusixhumi segagasi samamilimitha esathulwe ngaphambilini, esaziwa nangokuthi isixhumi sohlobo lwe-K, noma i-SMK, KMC, isixhumi se-WMP4.
Imvamisa yokusebenza yesixhumi esiyi-coaxial esingu-2.92mm ingafinyelela ku-46GHz phezulu kakhulu.Izinzuzo zomugqa wokudlulisa umoya zisetshenziselwa ireferensi, ukuze i-VSWR yayo iphansi futhi ukulahlekelwa kokufaka kukuncane.Isakhiwo sayo sifana nesixhumi esingu-3.5mm/SMA, kodwa ibhande lemvamisa liyashesha futhi ivolumu incane.Ingesinye sezixhumi zegagasi zamamilimitha ezisetshenziswa kakhulu emhlabeni.Ngokumiswa kobuchwepheshe be-millimeter wave coaxial kumathuluzi okuhlola ezempi e-China, izixhumi ze-coaxial ezingu-2.92mm zisetshenziswe kakhulu kubunjiniyela be-radar, izindlela zokuphikisa ze-elekthronikhi, ezokuxhumana ngesathelayithi, amathuluzi okuhlola neminye imikhakha.
2.92mm izinkomba zokusebenza eziphambili
I-impedance yesici: 50 Ω
Imvamisa yokusebenza: 0~46GHz
Isisekelo sokusebenzisana: IEC 60169-35
Ukuqina kwesixhumi: izikhathi eziyi-1000
Njengoba kushiwo ngaphambili, ukuxhumana kwe-2.92mm isixhumi nesixhumi esingu-3.5mm/SMA kuyafana, ngoba ukuhambisana ne-SMA nohlobo lwe-3.5 kucatshangelwa ngokugcwele ekwakhiweni komqhubi wangaphakathi nangaphandle kanye nobukhulu bobuso bokugcina besixhumi.
Njengoba kuboniswe kuThebula 1, ubukhulu bezixhumi zesilisa nesifazane zalezi zinhlobo ezintathu zezixhumi ziyahambisana, futhi ngokombono, zingaxhunywa ngaphandle koshintsho.Kodwa-ke, kufanele kuqashelwe ukuthi usayizi wabo we-conductor wangaphandle, imvamisa ephezulu, izinto ze-dielectric zokufaka insulating, njll. zihluke kakhulu, ukuze ukusebenza kokudlulisela kanye nokunemba kokuhlola kuzothinteka lapho izinhlobo ezahlukene zezixhumi zisetshenziselwa ukuxhuma.Kuphinde kushiwo ukuthi isixhumi sowesilisa se-SMA sinezidingo eziphansi zokubekezelela ukujula kwephinikhodi nokunwetshwa kwephini.Uma isixhumi sowesilisa se-SMA sifakwe kusixhumi sowesifazane esingu-3.5mm noma esingu-2.92mm, ukusetshenziswa kwesikhathi eside kuzodala umonakalo kusixhumi sowesifazane, ikakhulukazi umonakalo kusixhumi socezu lokulinganisa.Ngakho-ke, uma izixhumi ezihlukene zixhumene, ukuhlanganiswa okunjalo kokuxhumana kufanele futhi kugwenywe ngangokunokwenzeka.
