Kodi RF circulator ndi chiyani?
RF circulator ndi njira yopatsira nthambi yopanda mawonekedwe.Chozungulira cha RF cha ferrite chimapangidwa ndi mawonekedwe apakati ooneka ngati Y, monga akuwonetsera pachithunzichi.Iwo wapangidwa atatu nthambi mizere symmetrically anagawira pa ngodya ya 120 ° wina ndi mzake.Pamene kunja kwa maginito ndi zero, ferrite si maginito, kotero maginito mbali zonse ndi chimodzimodzi.Chizindikiro chikalowetsedwa kuchokera ku terminal 1, mphamvu ya maginito monga momwe ikuwonetsedwera mu chithunzi cha spin maginito imakondwera pa mphambano ya ferrite, ndipo chizindikirocho chidzaperekedwa ku kutuluka kuchokera ku terminal 2. Mofananamo, kulowetsa chizindikiro kuchokera ku terminal 2 kudzakhala kutumizidwa ku terminal 3, ndipo kulowetsa kwa siginecha kuchokera ku terminal 3 kudzatumizidwa ku terminal 1. Chifukwa cha ntchito yake yotumizira ma sign cyclic, imatchedwa RF circulator.
Kagwiritsidwe ntchito ka chozungulira: mlongoti wamba potumiza ndi kulandira ma sign
Kodi chodzipatula pawayilesi ndi chiyani?
Wailesi yodzipatula yamagetsi, yomwe imadziwikanso kuti unidirectional, ndi chipangizo chomwe chimatumiza mafunde a electromagnetic m'njira zonse.Mafunde a electromagnetic akatumizidwa kutsogolo, amatha kudyetsa mphamvu zonse ku mlongoti, zomwe zimapangitsa kuti mafunde owoneka bwino achoke mumlongoti.Chikhalidwe chopatsirana cha unidirectional ichi chingagwiritsidwe ntchito kudzipatula kukhudzidwa kwa kusintha kwa mlongoti pagwero la siginecha.Mwamakhalidwe, kulumikiza katundu ku doko lililonse la circulator kumatchedwa isolator.
Ma Isolators nthawi zambiri amagwiritsidwa ntchito poteteza zida.Mu ma amplifier amagetsi a RF mugawo loyankhulirana, amateteza chubu la amplifier mphamvu ndipo amayikidwa kumapeto kwa chubu chamagetsi.
