I-Coupler sisixhobo sokwenziwa esisetyenziselwa ukuhambisa imiqondiso phakathi kweesekethe okanye iinkqubo ezahlukeneyo. Isetyenziswa ngokubanzi kumaza kanomathotholo nakwiindawo zemicrowave. Umsebenzi wayo ophambili kukudibanisa inxalenye ethile yamandla ukusuka kumgca wothumelo oyintloko ukuya kumgca wesibini ukuphumeza ukuhanjiswa komqondiso, ukubeka iliso okanye impendulo.
Indlela i coupler esebenza ngayo
Izibini zihlala zinemigca yothumelo okanye izakhi ze-waveguide, ezihambisa inxalenye yamandla omqondiso kumgca ongundoqo kwizibuko lokudibanisa ngokusebenzisa isiphumo sokudityaniswa kwemimandla ye-electromagnetic. Le nkqubo yokudibanisa ayiyi kuchaphazela kakhulu ukuhanjiswa komqondiso womgca oyintloko, ukuqinisekisa ukusebenza okuqhelekileyo kwenkqubo.
Iintlobo eziphambili zee-couplers
I-Coupler ye-Directional: Inezibuko ezine kwaye iyakwazi ukudibanisa inxalenye yomqondiso wegalelo kwi-port ethile yokuphuma yokuhlola umqondiso kunye nokulawula impendulo.
I-Power Divider: Uhambisa izibonakaliso zegalelo kwii-ports ezininzi zemveliso ngokulinganayo, zihlala zisetyenziswa kwii-antenna arrays kunye ne-multi-channel systems.
I-Hybrid Coupler: Inokwahlula isignali yegalelo kwiimpawu ezininzi zemveliso ye-amplitude elinganayo kodwa izigaba ezahlukeneyo. Isetyenziswa ngokubanzi kwiinguqu zesigaba kunye ne-amplifiers elinganayo.
Iiparamitha eziphambili ze coupler
I-Coupling Factor: Ibonisa umlinganiselo wamandla esignali afunyenwe yi-port yokudibanisa kumandla okufaka, ngokuqhelekileyo abonakaliswe nge-decibels (dB).
Ukwahlulwa: Ilinganisa iqondo lophawu lokwahlulwa phakathi kwamazibuko angasetyenziswanga. Okukhona ukubekwa wedwa kuphezulu, kokukhona kuncinci ukuphazamiseka phakathi kwamazibuko.
Ilahleko yokuFaka: ibhekisa ekulahlekeni kwamandla xa umqondiso udlula kwi-coupler. Okuya kusezantsi ilahleko yokufaka, kokukhona ukuhanjiswa komqondiso kuphezulu.
Umlinganiselo wamaza omileyo (VSWR): ubonisa uthintelo lothintelo lwezibuko le coupler. I-VSWR isondele kwi-1, ngcono ukusebenza okufanayo.
Iindawo zokusetyenziswa kwee-couplers
Ukubekwa esweni komqondiso: Kwiinkqubo zerediyo zerediyo, i-couplers isetyenziselwa ukukhupha inxalenye yesignali yokubeka iliso kunye nokulinganisa ngaphandle kokuchaphazela ukuhanjiswa komqondiso oyintloko.
Ukuhanjiswa kwamandla: Kuluhlu lwe-eriyali, ii-couplers zisetyenziselwa ukusasaza ngokulinganayo imiqondiso kwizinto ze-eriyali ezizimeleyo ukufezekisa ukubethelwa kunye nokulawulwa komkhombandlela.
Ulawulo lwempendulo: Kwiisekethe ze-amplifier, i-couplers isetyenziselwa ukukhupha inxalenye yesignali yokuphuma kwaye iyondla ngokubuyisela kwigalelo ukuzinzisa inzuzo kunye nokuphucula umgca.
Ukwenziwa komqondiso: Kwiinkqubo zonxibelelwano, ii-couplers zingasetyenziselwa ukudibanisa imiqondiso emininzi ibe ngumqondiso omnye ukuze kube lula ukuhanjiswa kunye nokusebenza.
Inkqubela phambili yetekhnoloji yamva nje
Ngophuhliso olukhawulezayo lwetekhnoloji yonxibelelwano, iimfuno zokusebenza kwe-couplers ngokubhekiselele kwi-frequency ephezulu, amandla aphezulu kunye ne-bandwidth ebanzi zihlala zikhula. Kwiminyaka yakutshanje, iimveliso ze-coupler ezisekelwe kwizinto ezintsha kunye neenkqubo ezintsha ziye zaqhubeka zivela, kunye nelahleko ephantsi yokufakela, i-isolation ephezulu kunye nebhendi ye-frequency yokusebenza ebanzi, ukuhlangabezana neemfuno zonxibelelwano lwe-5G, iinkqubo ze-radar, unxibelelwano lwe-satellite kunye nezinye iinkalo.
ukuququmbela
Njengenxalenye ephambili kwiinkqubo ze-RF kunye ne-microwave, i-couplers idlala indima ebalulekileyo ekugqithiseni umqondiso, ukuhanjiswa kunye nokubeka iliso. Ukuqonda umgaqo wayo wokusebenza, uhlobo, iiparamitha eziphambili kunye neendawo zesicelo ziya kunceda ukukhetha i-coupler efanelekileyo kunye nokwandisa ukusebenza kwenkqubo kwiiprojekthi zangempela.
