Ka'idar asali ta na'urar watsawa ta RF da mai raba RF

A fannin fasahar microwave, na'urar watsawa ta RF da kuma na'urar rabawa ta RF sune muhimman na'urori guda biyu na ferrite da ake amfani da su wajen tsarawa da kuma ware siginar microwave.
Babban siffa ta waɗannan na'urori tana cikin rashin jituwarsu, wanda ke nufin cewa asarar siginar ba ta da yawa yayin watsawa gaba, yayin da take shan mafi yawan kuzarin yayin watsawa baya.
Wannan halayyar tana da alaƙa da hulɗar da ke tsakanin filin maganadisu da ferrite na microwave.
Filin maganadisu yana samar da tushen rashin amsawa, yayin da ferrite ke tantance mitar amsawar na'urar, wato, martanin da take bayarwa ga takamaiman mitar microwave.

Ka'idar aiki ta na'urar watsa siginar RF ita ce amfani da filin maganadisu don sarrafa siginar microwave. Lokacin da sigina ta shiga daga tashar shigarwa ɗaya, ana shiryar da ita zuwa wata tashar fitarwa, yayin da watsawar juyawa ta kusan toshewa.
Masu raba sigina sun ci gaba da yin hakan, ba wai kawai suna toshe siginar juyawa ba, har ma suna ware hanyoyin sigina guda biyu yadda ya kamata don hana tsangwama tsakanin sigina.

Ya kamata a lura cewa idan akwai filin maganadisu kawai ba tare da ferrite na microwave ba, watsa sigina zai zama na biyu, wato, tasirin watsawa gaba da baya zai zama iri ɗaya, wanda a bayyane yake bai dace da manufar ƙira na na'urar watsawa ta RF da mai raba RF ba. Saboda haka, kasancewar ferrite yana da mahimmanci don cimma aikin waɗannan na'urori.
