Yintoni i-RF circulator?
Isetyhula yeRF yinkqubo yothumelo yesebe eneempawu ezingatshintshiyo.I-ferrite RF circulator yenziwe ngesakhiwo seziko elibu-Y, njengoko kubonisiwe kulo mfanekiso.Iqulunqwe yimigca yesebe emithathu esasazwe ngokulinganayo kwi-engile ye-120 ° ukuya kwenye.Xa i-magnetic field yangaphandle ingu-zero, i-ferrite ayinamagnetized, ngoko i-magnetism kuwo onke amacala iyafana.Xa isignali ifaka igalelo kwi-terminal 1, indawo yamagnetic njengoko ibonisiwe kwi-spin magnetic character diagram iya kuba yimincili kwi-ferrite junction, kwaye umqondiso uya kuthunyelwa kwimveliso evela kwi-terminal 2. Ngokufanayo, igalelo lomqondiso kwi-terminal 2 liya kuba igqithiselwa kwitheminali yesi-3, kwaye igalelo lomqondiso elisuka kwitheminali 3 liya kudluliselwa kwitheminali yoku-1.
Ukusetyenziswa okuqhelekileyo kwesetyhula: i-eriyali eqhelekileyo yokuhambisa kunye nokufumana iimpawu
Yintoni isihlukanisi samaza kanomathotholo?
Isihlukanisi samaza kanomathotholo, ekwabizwa ngokuba sisixhobo esingekho macala onke, sisixhobo esisasaza amaza ombane ngendlela enye.Xa i-electromagnetic wave ihanjiswa kwicala eliya phambili, inokondla onke amandla kwi-eriyali, ibangele ukuthotywa okubalulekileyo kwamaza abonakalisiweyo ukusuka kwi-eriyali.Olu phawu lokudluliselwa kwe-unidirectional lungasetyenziselwa ukwahlula impembelelo yotshintsho lwe-antenna kumthombo womqondiso.Ukuthetha ngokwesakhiwo, ukudibanisa umthwalo nakweyiphi na i-port ye-circulator ibizwa ngokuba yi-isolator.
Ii-isolators zidla ngokusetyenziselwa ukukhusela izixhobo.Kwizikhuliseli zamandla eRF kwinkalo yonxibelelwano, ikakhulu zikhusela ityhubhu yeamplifier yamandla kwaye zibekwe ekupheleni kwetyhubhu yeamplifier yamandla.
