Ama-RF circulators angamadivayisi angenzi lutho anezimbobo ezintathu noma ngaphezulu ezingadlulisela amasignali e-RF ohlangothini olulodwa. Umsebenzi wayo oyinhloko ukulawula isiqondisindlela sokugeleza kwesignali, iqinisekisa ukuthi ngemva kokuba isignali ifakiwe isuka kwelinye imbobo, iphuma kuphela embobeni elandelayo ekhethiwe, futhi ngeke ibuye noma idluliselwe kwezinye izimbobo. Lesi sici senza ama-circulator asetshenziswe kabanzi ezinhlelweni ezahlukene ze-RF ne-microwave.
Izicelo eziyinhloko zama-circulator e-RF:
Umsebenzi we-Duplexer:
Izimo zohlelo lokusebenza: Kuzinhlelo ze-radar noma izinhlelo zokuxhumana ezingenantambo, isidlulisi nomamukeli ngokuvamile babelane ngothi olufanayo.
Indlela yokusebenzisa: Xhuma isidlulisi ku-port 1 yesiyingi, i-antenna echwebeni 2, kanye nomamukeli embobeni 3. Ngale ndlela, isignali yokudlulisa idluliselwa isuka ku-port 1 iye ku-port 2 (i-antenna), futhi isignali yokwamukela kudluliselwa kusuka ku-port 2 kuya ku-port 3 (umamukeli), ibona ukuhlukaniswa kokudlulisela nokwamukela ukuze kugwenywe ukuphazamiseka okulinganayo.
Umsebenzi we-Isolator:
Izimo zohlelo lokusebenza: Isetshenziselwa ukuvikela izingxenye ezibalulekile kumasistimu e-RF, njengezikhulisamandla, emonakalweni obangelwa amasignali abonisiwe.
Ukuqaliswa: Xhuma isidluliseli ku-port 1 yesiyingi, i-antenna embobeni 2, kanye nomthwalo ofanayo embobeni 3. Ngaphansi kwezimo ezijwayelekile, isignali idluliswa isuka ku-port 1 iye ku-port 2 (i-antenna). Uma kukhona ukungafani kokuphazamiseka ekugcineni kwe-antenna, okuholela ekubonakalisweni kwesignali, isignali ebonisiwe izodluliswa isuka ku-port 2 iye emthwalweni ofanayo we-port 3 futhi imunce, ngaleyo ndlela ivikele isidlulisi ethonyeni lesignali ebonisiwe.
Isikhulisi se-reflection:
Isimo sohlelo lokusebenza: Kwezinye izinhlelo ze-microwave, kuyadingeka ukukhombisa isignali emuva emthonjeni ukuze kuzuzwe imisebenzi ethile.
Ukuqaliswa: Ngokusebenzisa izici zokudlulisela eziqondisayo ze-circulator, isignali yokufaka iqondiswe embobeni ethile, futhi ngemva kokucubungula noma ukukhulisa, iboniswa emuva emthonjeni ngokusebenzisa i-circulator ukuze kuzuzwe ukuvuselelwa kwesignali.
Uhlelo lokusebenza ku-antenna:
Isimo sohlelo lokusebenza: Ezinhlwini ezisebenzayo ze-antenna (AESA) ezisebenzayo, amasiginali wamayunithi amaningi wezinti adinga ukuphathwa ngempumelelo.
Ukuqaliswa: I-circulator isetshenziselwa iyunithi ngayinye ye-antenna ukuqinisekisa ukuhlukaniswa okuphumelelayo kokudlulisela nokwamukela amasignali futhi kuthuthukise ukusebenza nokuthembeka kwe-antenna.
Ukuhlolwa kwaselabhorethri nesilinganiso:
Isimo sohlelo lokusebenza: Endaweni yokuhlola ye-RF, okokusebenza okuzwelayo kuyavikelwa ethonyeni lamasignali abonisiwe.
Ukuqaliswa: Faka i-circulator phakathi komthombo wesignali kanye nedivayisi engaphansi kokuhlolwa ukuze uqinisekise ukudluliswa kwesignali yendawo yonke futhi uvimbele amasignali abonisiwe ukuthi angalimazi umthombo wesignali noma athinte imiphumela yokulinganisa.
Izinzuzo zama-circulator e-RF:
Ukuhlukaniswa okuphezulu: Hlukanisa amasignali ngempumelelo phakathi kwezimbobo ezihlukene ukuze unciphise ukuphazamiseka.
Ukulahlekelwa kokufaka okuphansi: Qinisekisa ukusebenza kahle kanye nekhwalithi yokudluliswa kwesignali.
Umkhawulokudonsa obanzi: Isebenza kububanzi obuhlukahlukene befrikhwensi ukuhlangabezana nezidingo ezihlukene zohlelo lokusebenza.
Ngokuthuthuka okusheshayo kobuchwepheshe bokuxhumana okungenazintambo, ama-circulator e-RF adlala indima ebaluleke kakhulu ezinhlelweni zokuxhumana zesimanje. Ukusetshenziswa kwayo ekuxhumaneni kwe-duplex, ukuhlukaniswa kwesignali kanye nezinhlelo ze-antenna kuthuthukise kakhulu ukusebenza nokuthembeka kwesistimu. Ngokuzayo, ngokuthuthuka okuqhubekayo kobuchwepheshe, izinkambu zokufaka izicelo kanye nemisebenzi yama-circulator e-RF izoba banzi futhi ihluke kakhulu.
