Iyini i-RF circulator?
I-RF circulator iyisistimu yokudlulisa yegatsha enezici ezingashintshisani.I-ferrite RF circulator yakhiwe ngesakhiwo sesikhungo esimise okuka-Y, njengoba kuboniswe emfanekisweni.Yakhiwe ngemigqa yegatsha emithathu esabalaliswe ngokulinganayo nge-engeli engu-120 ° komunye nomunye.Uma insimu yamagnetic yangaphandle inguziro, i-ferrite ayinamagnetized, ngakho-ke i-magnetism kuzo zonke izinhlangothi iyafana.Lapho isignali ifakwa kusukela kutheminali 1, inkambu kazibuthe njengoba iboniswa kumdwebo wesici sozibuthe we-spin izojatshuliswa ekuhlanganeni kwe-ferrite, futhi isiginali izodluliselwa ekuphumeni ukusuka kutheminali 2. Ngokufanayo, okokufaka kwesignali okuvela kutheminali 2 kuzoba idluliselwe kutheminali 3, futhi okokufaka kwesignali okuvela kutheminali 3 kuzodluliselwa kutheminali 1. Ngenxa yomsebenzi wayo wokudlulisa isignali ngomjikelezo, ibizwa ngokuthi i-RF circulator.
Ukusetshenziswa okujwayelekile kwesiyingi: uthi olujwayelekile lokudlulisa nokwamukela amasignali
Yini isihlukanisi sefrikhwensi yomsakazo?
I-isolator yefrikhwensi yomsakazo, eyaziwa nangokuthi idivaysi engaqondile, iyithuluzi elidlulisa amagagasi kagesi ngendlela engaqondile.Lapho i-electromagnetic wave idluliswa iya phambili, ingaphakela wonke amandla ku-antenna, okubangele ukuncipha okukhulu kwamagagasi abonisiwe asuka othini.Lesi sici sokudluliswa kwe-unidirectional singasetshenziselwa ukuhlukanisa umthelela wezinguquko ze-antenna kumthombo wesignali.Ngokwesakhiwo, ukuxhuma umthwalo kunoma iyiphi ichweba le-circulator kubizwa ngokuthi i-isolator.
Ama-Isolators ngokuvamile asetshenziselwa ukuvikela amadivayisi.Ezikhulisini zamandla e-RF emkhakheni wezokuxhumana, zivikela ikakhulukazi ishubhu lesikhulisi samandla futhi zibekwe ekugcineni kweshubhu lesikhulisi samandla.
