I-Waveguide Circulator
Uhlolojikelele
Umgomo wokusebenza we-waveguide Circulator usekelwe ekudlulisweni kwe-asymmetric yenkundla kazibuthe.Uma isiginali ingena emugqeni wokudlulisa we-waveguide isuka ohlangothini olulodwa, izinto ezisetshenziswa kazibuthe zizoqondisa isignali ukuthi idlulisele kwelinye icala.Ngenxa yokuthi izinto kazibuthe zisebenza kuphela kumasiginali endaweni ethile, i-waveguide Circulator s ingafinyelela ukudluliswa kwamasiginali okukodwa.Phakathi naleso sikhathi, ngenxa yezakhiwo ezikhethekile zesakhiwo se-waveguide kanye nomthelela wezinto ezibonakalayo kazibuthe, i-waveguide Circulator ingafinyelela ukuhlukaniswa okuphezulu futhi ivimbele ukubonakaliswa kwesignali nokuphazamiseka.
I-waveguide Circulator inezinzuzo eziningi.Okokuqala, inokulahlekelwa okuphansi kokufaka futhi inganciphisa ukuncishiswa kwesignali nokulahlekelwa amandla.Okwesibili, i-waveguide Circulator inokuhlukaniswa okuphezulu, okungahlukanisa ngempumelelo amasiginali okokufaka nokuphumayo futhi igweme ukuphazamiseka.Ngaphezu kwalokho, i-waveguide Circulator inezici ze-broadband futhi ingasekela ububanzi obuningi bezidingo zomkhawulokudonsa.Ngaphezu kwalokho, ama-waveguide Circulators amelana namandla aphezulu futhi alungele izinhlelo zokusebenza zamandla aphezulu.
Ama-Waveguide Circulator asetshenziswa kakhulu ezinhlelweni ezahlukahlukene ze-RF kanye ne-microwave.Ezinhlelweni zokuxhumana, i-waveguide Circulator s isetshenziselwa ukuhlukanisa amasignali phakathi kwemishini yokudlulisa nokwamukela, ukuvimbela ukunanela nokuphazamiseka.Kumasistimu e-radar nawe-antenna, i-waveguide Circulator s isetshenziselwa ukuvimbela ukubonakaliswa kwesignali nokuphazamiseka, nokuthuthukisa ukusebenza kwesistimu.Ngaphezu kwalokho, i-waveguide Circulator s ingasetshenziselwa ukuhlola nokulinganisa izicelo, ukuhlaziya isignali kanye nocwaningo elabhorethri.
Lapho ukhetha futhi usebenzisa i-waveguide Circulator s, kuyadingeka ukuthi ucabangele amapharamitha athile abalulekile.Lokhu kufaka phakathi ububanzi befrikhwensi yokusebenza, obudinga ukukhetha ibanga elifanele lefrikhwensi;I-isolation degree, iqinisekisa umphumela omuhle wokuzihlukanisa;Ukulahlekelwa kokufaka, zama ukukhetha amadivaysi okulahlekelwa okuphansi;Amandla okucubungula amandla ukuze ahlangabezane nezidingo zamandla zesistimu.Ngokwezidingo ezithile zohlelo lokusebenza, izinhlobo ezahlukene kanye nokucaciswa kwe-waveguide Circulators kungakhethwa.
I-RF Waveguide Circulator iyisisetshenziswa esikhethekile esinamachweba amathathu esisetshenziselwa ukulawula nokuqondisa ukugeleza kwesignali ezinhlelweni ze-RF.Umsebenzi wayo oyinhloko ukuvumela amasignali ngendlela ethile ukuthi adlule ngenkathi evimbela amasignali ngakolunye uhlangothi.Lesi sici senza i-circulator ibe nenani elibalulekile lesicelo ekwakhiweni kwesistimu ye-RF.
Umgomo wokusebenza komzuliswano usekelwe ekuzungezweni kwe-Faraday kanye nezenzakalo ze-magnetic resonance kuma-electromagnetics.Ku-circulator, isignali ingena isuka kwelinye ichweba, igeleze iqonde endaweni ethile iye endaweni elandelayo, futhi ekugcineni ishiye imbobo yesithathu.Lesi siqondiso sokugeleza ngokuvamile sihambisana newashi noma ngokuphambene newashi.Uma isignali izama ukusabalala ngendlela engalindelekile, isiyingi izovimba noma imunce isignali ukuze igweme ukuphazamiseka nezinye izingxenye zesistimu kusukela kusiginali ehlehlayo.
I-RF waveguide circulator iwuhlobo olukhethekile lwesiyingi elisebenzisa isakhiwo se-waveguide ukudlulisa nokulawula amasignali e-RF.Ama-Waveguides awuhlobo olukhethekile lolayini wokudlulisela olungakhawulela amasiginali e-RF esiteshini esingokomzimba esincane, ngaleyo ndlela kunciphise ukulahleka kwesignali nokusakazeka.Ngenxa yalesi sici samagagasi, ama-RF waveguide circulators ayakwazi ukuhlinzeka ngamaza okusebenza aphezulu kanye nokulahlekelwa kwesignali ephansi.
Ezisetshenziswa ezingokoqobo, ama-RF waveguide circulator adlala indima ebalulekile ezinhlelweni eziningi ze-RF.Isibonelo, ohlelweni lwe-radar, ingavimbela amasignali e-echo ahlehlayo ukuthi angangeni ku-transmitter, ngaleyo ndlela ivikele isidlulisi ekulimaleni.Ezinhlelweni zokuxhumana, ingasetshenziswa ukuhlukanisa izimpondo ezidlulisa nokwamukela ukuvimbela isignali edluliswayo ukuthi ingangeni ngqo kumamukeli.Ngaphezu kwalokho, ngenxa yokusebenza kwayo kwemvamisa ephezulu kanye nezici zokulahlekelwa okuphansi, ama-RF waveguide circulators nawo asetshenziswa kabanzi emikhakheni efana nokuxhumana ngesathelayithi, isayensi yezinkanyezi yomsakazo, nama-accelerator ezinhlayiyana.
Kodwa-ke, ukuklama nokukhiqiza ama-RF waveguide circulator nakho kubhekana nezinselelo ezithile.Okokuqala, njengoba umgomo wayo wokusebenza ubandakanya ithiyori eyinkimbinkimbi ye-electromagnetic, ukuklama nokwenza kahle isizungeza kudinga ulwazi olujulile lobungcweti.Okwesibili, ngenxa yokusetshenziswa kwezakhiwo ze-waveguide, inqubo yokukhiqiza ye-circulator idinga imishini enembayo ephezulu kanye nokulawulwa kwekhwalithi okuqinile.Okokugcina, njengoba ichweba ngalinye le-circulator lidinga ukufanisa ngokunembile imvamisa yesignali ecutshungulwayo, ukuhlola kanye nokulungisa iphutha lomjikijeli nakho kudinga okokusebenza kochwepheshe nobuchwepheshe.
Sekukonke, i-RF waveguide circulator iyidivayisi ye-RF esebenza kahle, ethembekile, futhi enemvamisa ephezulu edlala indima ebalulekile ezinhlelweni eziningi ze-RF.Nakuba ukuklama nokukhiqiza imishini enjalo kudinga ulwazi nobuchwepheshe obuchwepheshile, ngokuqhubeka kobuchwepheshe kanye nokukhula kwesidingo, singalindela ukuthi ukusetshenziswa kwama-RF waveguide circulators kuzosakazeka kakhulu.
Ukuklanywa kanye nokukhiqizwa kwama-RF waveguide circulators kudinga ubunjiniyela obunembayo nezinqubo zokukhiqiza ukuze kuqinisekiswe ukuthi isizungeza ngasinye sihlangabezana nezidingo eziqinile zokusebenza.Ngaphezu kwalokho, ngenxa yethiyori eyinkimbinkimbi ye-electromagnetic ehilelekile kumgomo wokusebenza we-circulator, ukuklama nokwenza kahle isizungeza kudinga ulwazi olujulile lobungcweti.
