Na biyu, na'urar watsa sigina ta SMD tana da kyakkyawan aikin keɓewa. Suna iya ware siginar watsawa da karɓa yadda ya kamata, hana tsangwama, da kuma kiyaye amincin sigina. Fifikon wannan aikin keɓewa zai iya tabbatar da ingantaccen aikin tsarin da rage tsangwama ta sigina.
Bugu da ƙari, na'urar watsa sigina ta saman SMD ita ma tana da kyakkyawan yanayin zafi. Suna iya aiki a cikin kewayon zafin jiki mai faɗi, yawanci suna kaiwa daga -40 ° C zuwa +85 ° C, ko ma faɗi. Wannan yanayin zafin yana bawa na'urar watsa sigina ta saman SMD damar yin aiki cikin aminci a cikin yanayi daban-daban.
Hanyar marufi ta hanyar amfani da na'urorin da ke haɗa saman SMD (SMD surface mount Circulators) ita ma tana sauƙaƙa musu haɗawa da shigarwa. Suna iya shigar da na'urori masu zagaye kai tsaye a kan PCBs ta hanyar fasahar hawa, ba tare da buƙatar saka fil na gargajiya ko hanyoyin haɗa shi ba. Wannan hanyar marufi ta hanyar haɗa saman ba wai kawai tana inganta ingancin samarwa ba, har ma tana ba da damar haɗakar da yawa, ta haka tana adana sarari da sauƙaƙe ƙirar tsarin.
Bugu da ƙari, na'urorin watsawa na SMD suna da amfani mai yawa a cikin tsarin sadarwa mai yawan mita da kayan aikin microwave. Ana iya amfani da su don ware sigina tsakanin na'urorin ƙara ƙarfin RF da eriya, inganta aikin tsarin da kwanciyar hankali. Bugu da ƙari, ana iya amfani da na'urorin watsawa na SMD a cikin na'urori marasa waya, kamar sadarwa mara waya, tsarin radar, da sadarwa ta tauraron ɗan adam, don biyan buƙatun keɓewa da cire haɗin sigina mai yawan mita.
A taƙaice, na'urar da ke haɗa saman SMD (SMD surface mount Circulator) ƙarama ce, mai sauƙin sakawa, mai sauƙin ɗauka, tare da ɗaukar nauyin mitar, kyakkyawan aikin keɓewa, da kuma yanayin zafin jiki. Suna da amfani mai mahimmanci a fannoni kamar tsarin sadarwa mai yawan mita, kayan aikin microwave, da kayan aikin rediyo. Tare da ci gaba da haɓaka fasaha, na'urorin da ke haɗa saman SMD (SMD surface mount Circulators) za su taka muhimmiyar rawa a fannoni da yawa kuma su ba da gudummawa ga ci gaban fasahar sadarwa ta zamani.
Fasahar RF Surface Mount Technology (RF SMT) mai yaɗawa wani nau'in na'urar RF ne na musamman da ake amfani da shi don sarrafa da kuma sarrafa kwararar sigina a cikin tsarin RF. Ka'idar aikinta ta dogara ne akan juyawar Faraday da kuma yanayin maganadisu a cikin na'urorin lantarki. Babban fasalin wannan na'urar shine ba da damar sigina a cikin wani takamaiman alkibla su ratsa yayin da suke toshe sigina a akasin alkibla.
Mai watsa siginar RF SMT ya ƙunshi tashoshin jiragen ruwa guda uku, kowannensu zai iya zama shigarwa ko fitarwa. Lokacin da sigina ta shiga tashar jiragen ruwa, ana tura ta zuwa tashar jiragen ruwa ta gaba sannan ta fita daga tashar jiragen ruwa ta uku. Alkiblar kwararar wannan siginar yawanci tana juyawa ne a hannun agogo ko akasin agogo. Idan siginar ta yi ƙoƙarin yaɗuwa a cikin alkiblar da ba a zata ba, mai watsa siginar zai toshe ko ya sha siginar don guje wa tsangwama ga wasu sassan tsarin daga siginar da ta juye.
Babban fa'idodin na'urorin zagayawa na RF SMT sune ƙarancin ƙarfinsu da kuma haɗakarsu sosai. Saboda amfani da fasahar hawa saman, ana iya shigar da wannan na'urar zagayawa kai tsaye a kan allon zagayawa ba tare da buƙatar ƙarin wayoyi ko mahaɗin haɗawa ba. Wannan ba wai kawai yana rage girma da nauyin kayan aiki ba, har ma yana sauƙaƙa tsarin shigarwa da kulawa. Bugu da ƙari, saboda ƙirarsa mai ƙarfi, na'urorin zagayawa na RF SMT galibi suna da ingantaccen aiki da aminci.
A aikace-aikace na aikace-aikace, na'urorin watsawa na RF SMT suna taka muhimmiyar rawa a cikin tsarin RF da yawa. Misali, a cikin tsarin radar, yana iya hana siginar amsawa ta baya shiga mai watsawa, ta haka yana kare mai watsawa daga lalacewa. A cikin tsarin sadarwa, ana iya amfani da shi don ware eriya masu watsawa da karɓa don hana siginar da aka watsa shiga kai tsaye ta mai karɓa. Bugu da ƙari, saboda ƙarancinsa da haɗin kai mai yawa, ana amfani da na'urar watsawa ta RF SMT sosai a fannoni kamar motocin sama marasa matuƙi da sadarwa ta tauraron ɗan adam.
Duk da haka, ƙira da ƙera na'urorin watsawa na RF SMT suma suna fuskantar wasu ƙalubale. Na farko, tunda ƙa'idar aikinta ta ƙunshi ka'idar lantarki mai rikitarwa, tsarawa da inganta na'urar watsawa tana buƙatar zurfin ilimin ƙwararru. Na biyu, saboda amfani da fasahar hawa saman, tsarin kera na'urar watsawa yana buƙatar kayan aiki masu inganci da kuma kula da inganci mai tsauri. A ƙarshe, kamar yadda kowace tashar na'urar watsawa ke buƙatar daidaita mitar siginar da ake sarrafawa daidai, gwaji da gyara na'urar watsawa kuma yana buƙatar kayan aiki da fasaha na ƙwararru.
