Kumasekhethi e-RF kanye ne-microwave, ama-circulator nama-isolator ngamathuluzi amabili abalulekile asetshenziswa kabanzi ngenxa yemisebenzi yawo ehlukile kanye nezicelo. Ukuqonda izici zabo, imisebenzi kanye nezimo zohlelo lokusebenza kuzosiza onjiniyela bakhethe izixazululo ezifanele kumiklamo yangempela, ngaleyo ndlela kuthuthukiswe ukusebenza kwesistimu nokuthembeka.
1. Isiyingi: Imenenja yokuqondisa amasignali
1. Yini i-circulator?
I-circulator iyisisetshenziswa esingashintshisani esivame ukusebenzisa izinto ze-ferrite kanye nenkundla kazibuthe yangaphandle ukuze kuzuzwe ukudluliswa kwamasiginali okukodwa. Ivamise ukuba nezimbobo ezintathu, futhi amasiginali angadluliselwa kuphela phakathi kwezimbobo ngendlela engashintshi. Isibonelo, ukusuka ku-port 1 ukuya ku-port 2, kusukela ku-port 2 kuya ku-port 3, futhi kusukela ku-port 3 kubuyele embobeni 1.
2. Imisebenzi esemqoka ye-circulator
Ukusatshalaliswa kwesiginali nokuhlanganisa: sabalalisa amasiginali okokufaka ezimbobeni ezihlukene zokukhiphayo ngendlela engaguquki, noma hlanganisa amasiginali ukusuka ezimbotsheni eziningi uye embobeni eyodwa.
Dlulisa futhi wamukele ukuhlukaniswa: kusetshenziswa njenge-duplexer ukuze kuzuzwe ukuhlukaniswa kokudlulisa nokwamukela amasiginali ngothi olulodwa.
3. Izici zama-circulator
Ukungahoshelani: amasiginali angadluliselwa ohlangothini olulodwa kuphela, ukugwema ukuphazamiseka okuhlehlayo.
Ukulahlekelwa kokufaka okuphansi: ukulahleka kwamandla aphansi ngesikhathi sokudlulisa isignali, kulungele ikakhulukazi izinhlelo zokusebenza zefrikhwensi ephezulu.
Ukusekelwa kwe-Wideband: kungamboza ububanzi befrikhwensi ukusuka ku-MHz kuye ku-GHz.
4. Izicelo ezijwayelekile zama-circulator
Isistimu ye-radar: ihlukanisa isidlulisi kumamukeli ukuvimbela amasiginali okudlulisa amandla aphezulu ukuthi angalimazi idivayisi eyamukelayo.
Isistimu yokuxhumana: isetshenziselwa ukusatshalaliswa kwesiginali kanye nokushintshwa kwama-antenna amaningi.
Uhlelo lwe-antenna: lusekela ukuhlukaniswa kwamasiginali adlulisiwe nawamukelwe ukuze kuthuthukiswe ukuzinza kwesistimu.
II. I-Isolator: isithiyo sokuvikela isignali
1. Yini isihlukanisi?
Ama-Isolators ayindlela ekhethekile yama-circulator, imvamisa enamachweba amabili kuphela. Umsebenzi wayo oyinhloko ukucindezela ukubonakaliswa kwesignali nokugeleza emuva, ukuvikela imishini ebucayi ekuphazamisekeni.
2. Imisebenzi esemqoka yezihlukanisi
Ukuhlukaniswa kwesignali: vimbela amasignali abonisiwe ukuthi ageleze abuyele kumadivayisi angaphambili (njengama-transmitter noma izikhulisamandla) ukuze ugweme ukushisisa ngokweqile noma ukonakala kokusebenza kwemishini.
Ukuvikelwa kwesistimu: kumasekhethi ayinkimbinkimbi, ama-isolator angavimbela ukuphazamiseka phakathi kwamamojula aseduze futhi athuthukise ukwethembeka kwesistimu.
3. Izici zezihlukanisi
Ukudluliswa kwe-unidirectional: isignali ingadluliselwa kuphela kusukela ekugcineni kokufaka kuya ekugcineni kokuphumayo, futhi isignali ehlanekezelwe iyacindezelwa noma imuncwe.
Ukuhlukaniswa okuphezulu: kunikeza umphumela wokucindezelwa okuphezulu kakhulu kumasignali abonisiwe, ngokuvamile afika ku-20dB noma ngaphezulu.
Ukulahlekelwa kokufaka okuphansi: kuqinisekisa ukuthi ukulahleka kwamandla ngesikhathi sokudluliselwa kwesignali evamile kuphansi ngangokunokwenzeka.
4. Ukusetshenziswa okujwayelekile kwezihlukanisi
Ukuvikelwa kwesikhulisi se-RF: vimbela amasiginali abonisiwe ekubangeleni ukusebenza okungazinzile noma ukulimala kwesikhulisi.
Uhlelo lokuxhumana okungenantambo: hlukanisa imojula ye-RF ohlelweni lwe-antenna esiteshini.
Izinto zokuhlola: susa amasiginali abonisiwe ensimbini yokulinganisa ukuze uthuthukise ukunemba kokuhlolwa.
III. Ungakhetha kanjani idivayisi efanele?
Lapho uklama amasekhethi e-RF noma ama-microwave, ukukhetha kwesiyingi noma isihlukanisi kufanele kusekelwe ezidingweni ezithile zohlelo lokusebenza:
Uma udinga ukusabalalisa noma ukuhlanganisa amasignali phakathi kwezimbobo eziningi, ama-circulator ayakhethwa.
Uma inhloso enkulu kuwukuvikela idivayisi noma ukunciphisa ukuphazamiseka kumasignali abonisiwe, izihlukanisa ziyinketho engcono.
Ukwengeza, ububanzi befrikhwensi, ukulahlekelwa kokufaka, izimfuneko zokuhlukaniswa kanye nosayizi wocingo kufanele kucatshangwe ngokucophelela ukuze kuqinisekiswe ukuthi izinkomba zokusebenza zesistimu ethile ziyahlangatshezwa.
IV. Amathrendi Okuthuthukisa Ikusasa
Ngokuthuthukiswa kobuchwepheshe bokuxhumana okungenantambo, isidingo se-miniaturization kanye nokusebenza okuphezulu kwamadivayisi we-RF nama-microwave siyaqhubeka nokwanda. Amasekhula kanye nama-isolator nawo athuthuka kancane kancane ngezindlela ezilandelayo:
Ukusekelwa kwefrikhwensi ephezulu: ukusekela amabhendi wamaza amamilimitha (afana ne-5G ne-millimeter wave radar).
Idizayini ehlanganisiwe: ihlanganiswe namanye amadivayisi e-RF (njengezihlungi nezihlukanisi zamandla) ukuze kuthuthukiswe ukusebenza kwesistimu.
Izindleko eziphansi kanye ne-miniaturization: sebenzisa izinto ezintsha nezinqubo zokukhiqiza ukuze unciphise izindleko futhi uzivumelanise nezidingo zemishini yokugcina.
