Emibuthanweni ye-RF ne-microwave, amasetheli kanye nama-isolators ngamadivayisi amabili aqakathekile asetshenziswa kabanzi ngenxa yemisebenzi yawo eyingqayizivele kanye nezicelo. Ukuqonda izici zabo, imisebenzi kanye nezimo zohlelo lokusebenza kuzosiza onjiniyela ukuthi bakhethe izixazululo ezifanele emiklamo yangempela, ngaleyo ndlela bathuthukise ukusebenza kohlelo nokwethembeka.
1. Isisekeli: Umphathi wokuqondisa wezimpawu
1. Uyini umpuli?
I-circulator iyithuluzi elingasuswanga elivame ukusebenzisa izinto zokwakha i-ferrite kanye namandla kazibuthe angaphandle ukufezekisa ukuhanjiswa kwezimpawu ezingaphandle. Imvamisa inamachweba amathathu, futhi amasiginali angadluliselwa kuphela phakathi kwamachweba endaweni efanele. Isibonelo, ukusuka ePort 1 kuya ePort 2, kusuka ePort 2 kuya ePort 3, futhi kusuka ePort 3 Buyela ePort 1.
2. Imisebenzi esemqoka yesipuli
Ukusatshalaliswa kwesiginali nokuhlanganiswa: Sabalalisa amasiginali wokufaka kumachweba ahlukene okukhipha endaweni eqondile, noma uhlanganise amasiginali kusuka kumachweba amaningi ethekwini elilodwa.
Dlulisa futhi wamukele ukwahlukaniswa: Kusetshenziswe njenge-duplecler ukufezekisa ukwahlukaniswa kokudlulisa nokuthola amasiginali e-antenna eyodwa.
3. Izici zama-circulators
Ukungabuyisi: Amasiginali angadluliselwa kuphela endaweni eyodwa, agweme ukuphazamiseka okubuyela emuva.
Ukulahleka kokufaka okuphansi: ukulahleka kwamandla okuphansi ngesikhathi sokudluliselwa kwesiginali, ikakhulukazi ezisetshenziselwa izicelo ezivame kakhulu.
Ukuxhaswa kwe-Wide: kungamboza uhla lwemvamisa olubanzi kusuka ku-MHZ kuya ku-GHZ.
4. Ukusetshenziswa okujwayelekile kwama-circulators
Uhlelo lwe-Radar: Ihlukanisa i-transmitter kusuka kulowo owemukelayo ukuvikela amasiginali wokuhambisa amandla aphezulu ekulimazeleni idivaysi yokuthola.
Uhlelo Lokuxhumana: Kusetshenziselwa ukusatshalaliswa kwesiginali nokushintshwa kwe-antenna arransi.
Uhlelo lwe-Antenna: isekela ukwehlukaniswa kwezimpawu ezidluliselwe futhi zathola amasiginali wokuthuthukisa ukuqina kohlelo.
II. I-Isolator: Isithiyo sokuvikelwa sesiginali
1. Yini i-isolator?
Ama-Isolators ayindlela ekhethekile yama-circulators, imvamisa enamachweba amabili kuphela. Umsebenzi wayo oyinhloko ukucindezela ukuboniswa kwesiginali nokubuyela emuva, ukuvikela imishini ebucayi ekuphazanyisweni.
2. Imisebenzi eyinhloko ye-isolators
Ukuhlukaniswa kwesiginali: Vikela amasiginali abonisiwe ukuthi agelezele emuva kumadivayisi angaphambili (anjenge-transmitters noma ama-amplifiers wamandla) ukugwema ukuwohloka ngokweqile noma ukulimala kokusebenza kwemishini.
Ukuvikelwa kwesistimu: Kumasekethe ayinkimbinkimbi, ama-isolators angavimbela ukuphazamiseka phakathi kwamamojula aseduze futhi athuthukise ukuthembeka kohlelo.
3. Izici ze-isolators
Ukuhanjiswa kwe-Unidirirectional: Isiginali ingadluliselwa kuphela kusuka ekugcineni kokufaka kuya ekugcineni kokuphuma, futhi isiginali yokubuyela emuva icindezelwe noma imunwe.
I-Lolation ephezulu: Inikeza umphumela ophakeme kakhulu wokucindezela kwisiginali ebonisiwe, imvamisa kuze kube ngu-20DB noma ngaphezulu.
Ukulahleka kokufaka okuphansi: Kuqinisekisa ukuthi ukulahleka kwamandla ngesikhathi sokudluliselwa kwesiginali okujwayelekile kuphansi ngangokunokwenzeka.
4. Ukusetshenziswa okujwayelekile kwama-isolators
Ukuvikelwa kwe-RF Amplifier: Vikela amasiginali abonisiwe kusuka ekusebenzeni okungazinzile noma alimaze kwi-amplifier.
Uhlelo lokuxhumana olungenantambo: Hlukanisa imodyuli ye-RF esiteshini sesisekelo se-antenna system.
Amathuluzi okuhlola: Susa amasiginali abonisiwe ethuluzi lokulinganisa ukwenza ngcono ukunemba kokuhlola.
III. Ungayikhetha kanjani idivaysi efanele?
Lapho uklama amaseliphu e-RF noma ama-microwave, ukukhethwa kwesipuli noma i-isolator kufanele kususelwe kwizidingo ezithile zesicelo:
Uma udinga ukusabalalisa noma ukuhlanganisa amasiginali phakathi kwamachweba amaningi, kukhethwa ama-circuculata.
Uma inhloso enkulu ukuvikela idivaysi noma ukunciphisa ukuphazamiseka kusuka kumasiginali abonisiwe, ama-isolators akhetha kangcono.
Ngaphezu kwalokho, ibanga lemvamisa, ukulahleka kokufaka, izidingo zodwa kanye nosayizi wedivayisi kufanele kuthathwe njengokuqondakala ngokuphelele ukuqinisekisa ukuthi izinkomba zokusebenza kohlelo oluthile zihlangatshezwa.
IV. Izitayela Zokuthuthuka Okuzayo
Ngokuthuthukiswa kobuchwepheshe bokuxhumana okungenantambo, isidingo se-miniaturhalization kanye nokusebenza okuphezulu kwamadivayisi we-RF nama-microwave ayaqhubeka nokwanda. Ama-circulators kanye nama-isolators akhula kancane kancane kulezi zinkomba ezilandelayo:
Ukuxhaswa imvamisa ephezulu: Ama-Milimeter Milimeter Wave band (as 5g kanye nama-millimeter wave radar).
Idizayini ehlanganisiwe: Kuhlanganiswe namanye amadivaysi e-RF (njengokuhlunga kanye nabahlukanisi bamandla) ukwenza kahle ukusebenza kohlelo.
Izindleko eziphansi kanye ne-miniaturization: sebenzisa izinto ezintsha nezinqubo zokukhiqiza ukunciphisa izindleko futhi uzivumelanise nezidingo zemishini esibulalayo.
