Umgaqo wokuSebenza

Iisetyhulayitha kunye nezahluli zodwa zizinto ze-elektroniki ezingenzi nto, kwaye zizo kuphela kweemveliso ezingabuyiselaniyo phakathi kwawo onke amacandelo e-elektroniki. Babonisa ipropati yokuhanjiswa kwesignali ye-unidirectional kwisekethe, evumela ukuba iimpawu zihambe kwicala elinye ngelixa zikhusela ukuhamba kwesignali kwicala elingasemva.

    Isetyhulayitha

    Njengoko kuboniswe kumzobo, abajikelezi banamazibuko amathathu, kwaye umgaqo wabo wokusebenza ubandakanya ukuhanjiswa kwesignali ye-unidirectional ngomyalelo we-T→ ANT→R. Iimpawu ziya kuhamba ngokwendlela ekhankanyiweyo, kunye nelahleko encinci xa ithunyelwa ukusuka kwi-T→ANT, kodwa ilahleko ephezulu ebuyela umva xa isuka kwi-ANT→T. Ngokufanayo, ngexesha lokufumana umqondiso, kukho ilahleko encinci xa uhambisa ukusuka kwi-ANT→R kunye nelahleko ephezulu yokubuyisela umva xa uthumela kwi-R→ANT. Isalathiso semveliso sinokwenziwa ngokwezifiso malunga nokusebenza kwewotshi kunye ne-counterclockwise. Iisetyhulayitha zisetyenziswa ngokuqhelekileyo kumacandelo e-T/R.

    Uyedwa

    Njengoko kubonisiwe kumzobo, umgaqo wokusebenza we-isolator usekelwe kwisakhiwo se-port-port ye-circulator kunye nokongezwa kwe-resistor kwi-port enye, ukuyiguqula ibe ngamachweba amabini. Xa uthumela kwi-T→ ANT, kukho ilahleko encinci yesignali, ngelixa ininzi yesignali ebuya kwi-ANT ifunnwe yi-resistor, ifezekisa umsebenzi wokukhusela i-amplifier yamandla. Ngokufanayo, ingasetyenziselwa ukufumana umqondiso kuphela. I-Isolators ziqhele ukusetyenziswa kwi-single-transmit okanye i-single-receive components.

    Isetyhulayitha yeeJunction ezimbini

    Njengoko kubonisiwe kumzobo, umgaqo osebenzayo we-Dual-Junction Circulator ubandakanya ukudibanisa i-circulator kunye ne-isolator kwiyunithi enye. Olu yilo luguqulelo oluphuculweyo lwesetyhula, kwaye indlela yomqondiso ihlala iyi-T→ANT→R. Injongo yolu kuhlanganiswa kukujongana nomba wokubonakaliswa komqondiso xa umqondiso ufunyenwe kwi-R ukusuka kwi-ANT. Kwi-Dual-Junction Circulator, isignali ebonakaliswe ukusuka ku-R iqondiswe emva kwi-resistor ukuze ifakwe, ikhusela umqondiso obonakalisiweyo ekufikeleleni kwi-T port. Oku kufezekisa umsebenzi wokuhambisa umqondiso we-unidirectional we-circulator kunye nokukhuselwa kwe-amplifier yamandla.

    Isetyhulayitha ye-Triple-Junction

    Njengoko kuboniswe kumzobo, umgaqo osebenzayo we-Triple-Junction Circulator yongezwa kwe-Dual-Junction Circulator. Idibanisa i-isolator phakathi kwe-T→ANT kwaye yongeza ilahleko ephezulu ebuyela umva kunye ne-resistor eyongezelelweyo phakathi kwe-R→T. Olu luyilo lunciphisa kakhulu ukuba nokwenzeka kokonakalisa iamplifier yamandla. I-Triple-Junction Circulator inokwenziwa ngokwezifiso ngokusekelwe kuluhlu oluthile lwamaza, amandla, kunye neemfuno zobukhulu.
