Ama-circulator nama-isolator: amadivayisi ayinhloko kumasekethe e-RF nama-microwave

Kumasekethe e-RF kanye nama-microwave, ama-circulator nama-isolator angamadivayisi amabili abalulekile asetshenziswa kabanzi ngenxa yemisebenzi yawo eyingqayizivele kanye nezinhlelo zokusebenza. Ukuqonda izici zawo, imisebenzi kanye nezimo zohlelo lokusebenza kuzosiza onjiniyela ukukhetha izixazululo ezifanele emiklamo yangempela, ngaleyo ndlela bathuthukise ukusebenza kohlelo kanye nokuthembeka.

1. I-circulator: Umphathi wesiqondiso sezimpawu

1. Kuyini i-circulator?
I-circulator iyithuluzi elingashintshisani elivame ukusebenzisa izinto ze-ferrite kanye nensimu yamagnetic yangaphandle ukuze kufezwe ukudluliselwa kwezimpawu ngendlela eyodwa. Ngokuvamile inamachweba amathathu, futhi izimpawu zingadluliselwa kuphela phakathi kwamachweba ngendlela eqondile. Isibonelo, kusukela echwebeni 1 kuya echwebeni 2, kusukela echwebeni 2 kuya echwebeni 3, kanye nokusuka echwebeni 3 kuya echwebeni 1.
2. Imisebenzi eyinhloko ye-circulator
Ukusatshalaliswa nokuhlanganiswa kwesignali: ukusabalalisa izimpawu zokufaka kuma-port ahlukene okukhiphayo ngendlela eqondile, noma ukuhlanganisa izimpawu ezivela kuma-port amaningi zibe yi-port eyodwa.
Dlulisa futhi wamukele ukwahlukaniswa: kusetshenziswa njenge-duplexer ukufeza ukwahlukaniswa kokudlulisa nokwamukela izimpawu ku-antenna eyodwa.
3. Izici zama-circulator
Ukungashintshisani: izimpawu zingadluliselwa ohlangothini olulodwa kuphela, kugwenywe ukuphazamiseka okuphambene.
Ukulahlekelwa okuphansi kokufakwa: ukulahlekelwa kwamandla aphansi ngesikhathi sokudluliselwa kwesignali, okulungele kakhulu izinhlelo zokusebenza ezivame kakhulu.
Ukusekelwa kwe-Wideband: kungamboza ububanzi bemvamisa kusukela ku-MHz kuya ku-GHz.
4. Ukusetshenziswa okuvamile kwama-circulator
Uhlelo lwe-radar: luhlukanisa umthumeli kumamukeli ukuze kuvinjelwe amasignali okudlulisa amandla aphezulu ukuthi angalimazi idivayisi eyamukelayo.
Uhlelo lokuxhumana: olusetshenziselwa ukusatshalaliswa kwesignali kanye nokushintsha ama-array e-antenna amaningi.
Uhlelo lwe-antenna: lusekela ukuhlukaniswa kwezimpawu ezidlulisiwe nezamukelwe ukuze kuthuthukiswe ukuzinza kohlelo.

II. I-Isolator: isithiyo sokuvikela isignali

1. Kuyini i-isolator?
Ama-isolator ayindlela ekhethekile yama-circulator, ngokuvamile anezimbobo ezimbili kuphela. Umsebenzi wawo oyinhloko ukucindezela ukubonakaliswa kwesignali kanye nokugeleza emuva, ukuvikela imishini ebucayi ekuphazamisekeni.
2. Imisebenzi eyinhloko yabahlukanisi
Ukuhlukaniswa kwesignali: kuvimbela izimpawu eziboniswayo ukuthi zingabuyeli emuva kumadivayisi angaphambili (njengama-transmitter noma ama-power amplifiers) ukuze kugwenywe ukushisa ngokweqile noma ukuwohloka kokusebenza kwemishini.
Ukuvikelwa kwesistimu: kumasekethe ayinkimbinkimbi, ama-isolators angavimbela ukuphazamiseka okuhlangene phakathi kwamamojula aseduze futhi athuthukise ukuthembeka kwesistimu.
3. Izici zezihlukanisi
Ukudluliselwa okuqondisayo okukodwa: isignali ingadluliselwa kuphela kusukela ekugcineni kokufaka kuya ekugcineni kokukhipha, bese isignali ebuyela emuva iyacindezelwa noma imuncwe.
Ukuhlukaniswa okuphezulu: kunikeza umphumela wokucindezela ophezulu kakhulu kumasignali abonisiwe, ngokuvamile afinyelela ku-20dB noma ngaphezulu.
Ukulahlekelwa okuphansi kokufakwa: kuqinisekisa ukuthi ukulahlekelwa kwamandla ngesikhathi sokudluliselwa kwesignali evamile kuphansi ngangokunokwenzeka.
4. Ukusetshenziswa okuvamile kwama-isolators
Ukuvikelwa kwe-RF amplifier: kuvimbela amasignali abonakalayo ukuthi angabangeli ukusebenza okungazinzile noma ngisho nomonakalo ku-amplifier.
Uhlelo lokuxhumana olungenantambo: hlukanisa imojuli ye-RF ohlelweni lwe-antenna yesiteshi esiyisisekelo.
Imishini yokuhlola: susa izimpawu ezibonakalayo ethuluzini lokulinganisa ukuze uthuthukise ukunemba kokuhlola.

III. Ungayikhetha kanjani idivayisi efanele?

Uma uklama amasekethe e-RF noma ama-microwave, ukukhetha i-circulator noma i-isolator kufanele kusekelwe ezidingweni ezithile zohlelo lokusebenza:
Uma udinga ukusabalalisa noma ukuhlanganisa amasignali phakathi kwamachweba amaningi, ama-circulator ayathandwa.
Uma inhloso eyinhloko ukuvikela idivayisi noma ukunciphisa ukuphazamiseka okuvela kumasignali abonakalayo, ama-isolator angcono kakhulu.
Ngaphezu kwalokho, ububanzi bemvamisa, ukulahlekelwa kokufakwa, ukuhlukaniswa kanye nezidingo zosayizi wedivayisi kumele kucatshangelwe ngokuphelele ukuqinisekisa ukuthi izinkomba zokusebenza zesistimu ethile ziyahlangatshezwa.

IV. Imikhuba Yentuthuko Yesikhathi Esizayo

Ngokuthuthuka kobuchwepheshe bokuxhumana obungenantambo, isidingo sokuncishiswa kwamandla kagesi kanye nokusebenza okuphezulu kwamadivayisi e-RF kanye nama-microwave siyaqhubeka nokukhula. Ama-circulator nama-isolator nawo athuthuka kancane kancane kulezi zindlela ezilandelayo:
Ukusekelwa kwemvamisa ephezulu: ukusekela ama-millimeter wave bands (njenge-5G kanye ne-millimeter wave radar).
Umklamo ohlanganisiwe: uhlanganiswe namanye amadivayisi e-RF (njengezihlungi kanye nezihlukanisi zamandla) ukuze kuthuthukiswe ukusebenza kwesistimu.
Izindleko eziphansi kanye nokunciphisa: sebenzisa izinto ezintsha kanye nezinqubo zokukhiqiza ukuze unciphise izindleko futhi uzivumelanise nezidingo zemishini yokugcina.
