1. Gabatarwa zuwa mai haɗin SMA
Yawancin lokaci ana amfani da SMA don samar da haɗin RF tsakanin allon kewayawa.Yawancin abubuwan haɗin microwave sun haɗa da masu tacewa, attenuators, mahaɗa da oscillators.Mai haɗin haɗin yana da zaren haɗin haɗin waje na waje, wanda ke da siffar hexagon kuma ana iya ƙarfafa shi da maƙarƙashiya.Ana iya ƙarfafa su zuwa madaidaicin madaidaicin ta hanyar amfani da maɗaukaki na musamman, ta yadda za a iya samun haɗin haɗi mai kyau ba tare da ƙari ba.
An ƙera mai haɗin SMA na farko don kebul na coaxial 141 Semi-rigid.Ana iya kiran mai haɗin SMA na asali mafi ƙanƙanta, saboda cibiyar cibiyar haɗin gwiwar ta samar da maɓallin tsakiya na haɗin gwiwa, kuma babu buƙatar canzawa tsakanin mai gudanarwa na coaxial da tsakiya na cibiyar sadarwa na musamman.
