Umehluko phakathi kwama-isolators we-RF kanye nama-RF watolika

Kuzinhlelo zokusebenza ezisebenzayo, ama-isolators e-RF kanye nama-RF watolika avame ukushiwo ngasikhathi sinye.
Buyini ubudlelwano phakathi kwama-isolators e-RF kanye nabasekeli be-RF? Uyini umehluko?
Lo mbhalo uzogxila ekuxoxeni ngalezi zinkinga.
I-Radio Frequency Isorator, eyaziwa nangokuthi idivaysi engavumi, iyithuluzi elidlulisela amagagasi e-electromagnetic endaweni eyodwa. Lapho amagagasi we-electromagnetic esakazeka khona lapho, angokondla wonke amandla emthwalweni futhi adale ama-attibiation aphambili kumagagasi abonisiwe avela emthwalweni.
Ama-RF watolika amasistimu wokuhambisa amagatsha anezici ezingekho emthethweni. Ama-purstators asetshenziswa kakhulu we-FRRITE RF ama-jpction purcicaterators we-Y

1,Yini i-ilsofator ye-rf?
I-Radio Frequency Isorator, eyaziwa nangokuthi idivaysi engavumi, iyithuluzi elidlulisela amagagasi e-electromagnetic endaweni eyodwa. Lapho amagagasi e-electromagnetic esakazeka khona lapho uqonde phambili, angokondla wonke amandla emthwalweni futhi adale ukuqashelwa okukhulu kwamagagasi abonisiwe emthwalweni. Lesi sici sokudlulisa esingalingani singasetshenziselwa ukwahlukanisa umthelela wezinguquko zomthwalo emthonjeni wesiginali. Ukuthatha insimu ehambisa i-Iholotor njengesibonelo, kubuye kuchaze umthetho osebenzayo we-Ferrite RF Isolator.

Ama-Isolators we-Field Shift asuselwa emiphumeleni ehlukene yokushintshwa kwenkundla yeFerrite ngezindlela zamagagasi adluliselwe ezinkomba ezimbili. Ingeza amapuleti e-attenuation ohlangothini lweshidi le-ferrite, futhi ngenxa yokuphambuka okuhlukile kwamasimu akhiqizwa izinkomba ezimbili ezidluliselwe eceleni kwe-attenuation ( I-Attenuation kanye ne-attenuation enkulu yokubuyela emuva, njengoba kukhonjisiwe kuMfanekiso2.

2,Yini ama-pundators we-RF?
Ama-RF watolika amasistimu wokuhambisa amagatsha anezici ezingekho emthethweni. Ama-purstators asetshenziswa kakhulu we-FRRITITITE RF ama-RF ama-RF Lapho amandla kazibuthe angaphandle angu-zero, i-ferrite ayikaze ibekiwe, ngakho-ke ubusika kuzo zonke izinkomba kufana. Lapho isinali lifakwa kusuka kulayini wegatsha "①", amandla kazibuthe njengoba kukhonjisiwe kuMfanekiso 3 (b) azojabula e-Ferrite Junction. Ngenxa yezimo ezifanayo zamagatsha "②, ③", isiginali ayiphumi ezingxenyeni ezilinganayo. Lapho kufakwa i-magnetic field efanelekile, i-ferrite ikhubazekile, futhi ngenxa yomphumela we-anisotropy, inkambu ye-electromagnetic njengoba kukhonjisiwe kuMfanekiso 3 (C) ijabule ekuhlanganeni kwe-Ferrite. Lapho kufakwa i-magnetic field efanelekile, i-FERRITE ilawulwa, futhi ngenxa yomphumela we-anisotropy, kukhona umphumela wesiginali egatsheni "②", kuyilapho inkambu kagesi egatsheni "③" ingaphandle kokukhipha. Lapho futhi okokufaka okuvela egatsheni "②", igatsha "③" likhipha, ngenkathi igatsha "①" alinakukhishwa; Lapho okokufaka okuvela egatsheni "③", igatsha "①" linokuphuma ngenkathi igatsha "②" alinakukhishwa. Kungabonakala ukuthi kwakha ukusakazwa okungaqinisekisiwe kwe- "①" → "②" → "①" → ""
