ISetyhulayidi ye-waveguide ineenzuzo ezininzi.Okokuqala, inelahleko ephantsi yokufaka kwaye inokunciphisa ukuthomalalisa umqondiso kunye nokulahleka kwamandla.Okwesibini, i-Circulator ye-waveguide ine-isolation ephezulu, enokwahlula ngokufanelekileyo igalelo kunye neempawu zemveliso kunye nokuphepha ukuphazamiseka.Ukongeza, i-Circulator ye-waveguide ineempawu ze-broadband kwaye inokuxhasa uluhlu olubanzi lweemfuno ze-bandwidth.Ngaphaya koko, i-waveguide Circulator s iyaxhathisa kumandla aphezulu kwaye ifanelekile kwizicelo zamandla aphezulu.
I-Waveguide Circulator s isetyenziswa ngokubanzi kwiinkqubo ezahlukeneyo zeRF kunye ne-microwave.Kwiinkqubo zonxibelelwano, i-waveguide Circulator s isetyenziselwa ukwahlula imiqondiso phakathi kokudlulisa kunye nokufumana izixhobo, ukuthintela i-echoes kunye nokuphazamiseka.Kwiinkqubo ze-radar kunye ne-antenna, i-waveguide Circulator s isetyenziselwa ukukhusela ukubonakalisa umqondiso kunye nokuphazamiseka, kunye nokuphucula ukusebenza kwenkqubo.Ukongeza, i-waveguide Circulator s ingasetyenziselwa ukuvavanya kunye nezicelo zokulinganisa, uhlalutyo lomqondiso kunye nophando kwibhubhoratri.
Xa ukhetha kwaye usebenzisa i-waveguide Circulator s, kuyimfuneko ukuqwalasela ezinye iiparamitha ezibalulekileyo.Oku kuquka uluhlu lwamaza okusebenza, olufuna ukukhetha uluhlu olufanelekileyo lwamaza;Isidanga sokwahlukaniswa, ukuqinisekisa isiphumo esihle sokwahlukaniswa;Ilahleko yokufaka, zama ukukhetha izixhobo zelahleko ephantsi;Ukukwazi ukusetyenzwa kwamandla ukuhlangabezana neemfuno zamandla enkqubo.Ngokweemfuno ezithile zesicelo, iintlobo ezahlukeneyo kunye neenkcukacha ze-waveguide Circulators zingakhethwa.
I-RF Waveguide Circulator sisixhobo esikhethekileyo esinezibuko ezintathu esisetyenziselwa ukulawula nokukhokela ukuhamba komqondiso kwiinkqubo zeRF.Umsebenzi wayo oyintloko kukuvumela imiqondiso kwindlela ethile ukuba idlule ngelixa ivimbela izibonakaliso kwicala elichaseneyo.Olu phawu lwenza ukuba umjikelo ube nexabiso lesicelo esibalulekileyo kuyilo lwenkqubo yeRF.
Umgaqo wokusebenza we-circulator usekelwe kwi-Faraday rotation kunye ne-magnetic resonance phenomena kwi-electromagnetics.Kwi-circulator, isibonakaliso singena ukusuka kwelinye izibuko, sihamba ngendlela ethile kwi-port elandelayo, kwaye ekugqibeleni sishiya i-port yesithathu.Olu lwathiso lokuhamba ludla ngokuba ngasekunene okanye ngasekunene.Ukuba isignali izama ukusabalalisa ngendlela engalindelekanga, i-circulator iya kuvala okanye ithathe isignali ukuze igweme ukuphazamiseka kwezinye iindawo zenkqubo ukusuka kwisignali ebuyayo.
I-RF waveguide circulator luhlobo olukhethekileyo lomjikelo osebenzisa i-waveguide structure ukuhambisa nokulawula imiqondiso yeRF.I-Waveguides luhlobo olukhethekileyo lwelayini yothumelo enokunciphisa imiqondiso yeRF kumjelo omxinwa womzimba, ngaloo ndlela inciphisa ukulahleka komqondiso kunye nokusasazeka.Ngenxa yolu phawu lwesikhokelo samaza, ii-RF waveguide circulators ziyakwazi ukubonelela ngamaza okusebenza aphezulu kunye nelahleko yomqondiso osezantsi.
Kwizicelo ezisebenzayo, ii-RF waveguide circulators zidlala indima ebalulekileyo kwiinkqubo ezininzi zeRF.Ngokomzekelo, kwinkqubo ye-radar, inokuthintela izibonakaliso ze-echo ezibuyela umva ekungeneni kwi-transmitter, ngaloo ndlela ikhusela umthumeli kumonakalo.Kwiinkqubo zonxibelelwano, ingasetyenziselwa ukwahlula i-eriyali yokudlulisa kunye nokufumana ukuthintela umqondiso ogqithisiweyo ukuba ungene ngqo kummkeli.Ukongeza, ngenxa yokusebenza kwayo okuphezulu okujikelezayo kunye neempawu zelahleko ephantsi, ii-RF waveguide circulators zikwasetyenziswa ngokubanzi kumasimi anjengonxibelelwano ngesatellite, iastronomy yerediyo, kunye ne-particle accelerators.
Nangona kunjalo, ukuyila kunye nokwenza ii-RF waveguide circulators nazo zijongene nemingeni ethile.Okokuqala, njengoko umgaqo wayo wokusebenza ubandakanya ithiyori entsonkothileyo ye-electromagnetic, ukuyila kunye nokwandisa umjikelo kufuna ulwazi olunzulu lobuchwephesha.Okwesibini, ngenxa yokusetyenziswa kwezakhiwo ze-waveguide, inkqubo yokuvelisa i-circulator idinga izixhobo ezichanekileyo eziphezulu kunye nokulawula umgangatho ongqongqo.Okokugqibela, njengoko izibuko ngalinye lesetyhula lifuna ukuchaneka ngokuchanekileyo ukujikeleza komqondiso ocutshungulwayo, ukuvavanywa kunye nokulungiswa kweempazamo kwisetyhula kufuna izixhobo zobuchwephesha kunye netekhnoloji.
