Isidibanisi se-SMA sisidibanisi esisetyenziswa ngokubanzi semi precision i-RF kunye ne-microwave, ilungele ngakumbi uqhagamshelo lweRF kwiinkqubo zombane ezinamaza ukuya kuthi ga kwi-18 GHz okanye nangaphezulu.Izixhumi ze-SMA zineendlela ezininzi, amadoda, abafazi, ngokuthe tye, i-angle echanekileyo, ukufakwa kwe-diaphragm, njl., enokufikelela kwiimfuno ezininzi.Ubungakanani bayo obuncinci kakhulu buvumela ukuba isetyenziswe, nakwizixhobo zombane ezincinci.
1, Intshayelelo kwi-SMA isinxibelelanisi
I-SMA idla ngokusetyenziselwa ukubonelela ngoqhagamshelwano lweRF phakathi kweebhodi zesekethe.Amacandelo amaninzi e-microwave aquka izihluzi, izithinteli, izixube kunye nee-oscillators.Isidibanisi sinonxibelelwano oludityanisiweyo lwangaphandle, olunemilo yehexagon kwaye lunokuqiniswa ngesitshixo.Ziyakwazi ukuqiniswa kwi-tightness echanekileyo usebenzisa i-wrench ekhethekileyo ye-torque, ukwenzela ukuba uxhulumaniso oluhle lunokufezekiswa ngaphandle kokugqithisa.
Isidibanisi sokuqala se-SMA senzelwe i-141 semi-rigid coaxial cable.Isidibanisi sokuqala se-SMA sinokubizwa ngokuba sisidibanisi esincinci, kuba isikhungo sekhebula le-coaxial senza iphini eliphakathi loqhagamshelo, kwaye akukho mfuneko yokutshintsha phakathi komqhubi weziko le-coaxial kunye nepini ephakathi yekhonkco ekhethekileyo.
Inzuzo yayo kukuba i-dielectric yekhebula idibaniswe ngokuthe ngqo kwi-interface ngaphandle kwe-gap yomoya, kwaye i-disadvantage yayo kukuba kuphela inani elilinganiselweyo lokuqhagamshelwa / ukuqhawula imijikelezo inokuqhutywa.Nangona kunjalo, kwizicelo ezisebenzisa i-semi-rigid coaxial cables, oku akunakwenzeka ukuba kube ngumcimbi, njengoko ukufakela ngokuqhelekileyo kulungiswe emva kokuhlanganisana kokuqala.
2. Ukusebenza kwesinxibelelanisi se-SMA
Isidibanisi se-SMA senzelwe ukuba sibe ne-impedance eqhubekayo ye-50 ohms kwikhonkco.Izihlanganisi ze-SMA zaye zayilwa ekuqaleni zaza zamiselwa ukusebenza ukuya kuthi ga kwi-18 GHz, nangona ezinye iinguqulelo zinesantya esiphezulu se-12.4 GHz kwaye ezinye iinguqulelo zichongwe njenge-24 okanye i-26.5 GHz.Imida ephezulu yamaza osasazo anokufuna ukusebenza ngelahleko ephezulu yokubuya.
Ngokubanzi, izihlanganisi ze-SMA zinembonakalo ephezulu kunezinye izihlanganisi ukuya kuthi ga kwi-24 GHz.Oku kungenxa yobunzima bokulungisa ngokuchanekileyo inkxaso ye-dielectric, kodwa nangona lo bunzima, abanye abavelisi baye bakwazi ukunqoba le ngxaki ngokufanelekileyo kwaye banako ukutyumba izixhumi zabo ze-26.5GHz yokusebenza.
Kwiintambo eziguquguqukayo, umda wokuphindaphinda udla ngokumiselwa yintambo kunesidibanisi.Oku kungenxa yokuba izihlanganisi ze-SMA zamkela iintambo ezincinci kakhulu, kwaye ilahleko yazo ngokwemvelo inkulu kunezo ziqhagamshelo, ngakumbi kumaxesha anokuthi asebenzise.
3, Amandla alinganisiweyo ekhonkco ye-SMA
Kwezinye iimeko, ireyithingi yesiqhagamshelo se-SMA inokubaluleka.Ipharamitha ephambili yokumisela umthamo wokuphatha amandla we-mating shaft connector kukuba inokuhambisa i-high current kwaye igcine ukunyuka kobushushu kwiqondo lokushisa eliphakathi.
Umphumo wokufudumeza ubangelwa ikakhulu kukuchasana koqhagamshelwano, olungumsebenzi wendawo yokudibanisa kunye nendlela yokudibanisa iipads kunye.Ummandla ophambili luqhagamshelwano oluphakathi, ekufuneka lwenziwe ngokufanelekileyo kwaye luhlanganiswe kakuhle.Kufuneka kuqatshelwe ukuba umndilili wamandla okalisiweyo wehla ngokuphindaphindiweyo ngenxa yokuba ilahleko yokuxhathisa inyuka ngokuphindaphindiweyo.
Idatha yokusetyenzwa kwamandla kwizihlanganisi ze-SMA zohluka kakhulu phakathi kwabavelisi, kodwa amanani athile abonisa ukuba abanye banokuqhuba i-500 watts kwi-1GHz kwaye behle ukuya ngaphantsi kancinci kune-200 watts kwi-10GHz.Nangona kunjalo, le yidatha elinganisiweyo, enokuthi ibe phezulu ngokwenene.
Kwi-SMA i-microstrip isixhumi sineentlobo ezine: uhlobo olukhutshwayo, uhlobo lwe-TTW yensimbi, uhlobo oluPhakathi lwe-TTW, uhlobo lokudibanisa ngokuthe ngqo.Nceda ucofe ku:https://www.dbdesignmw.com/microstrip-connector-selection-table/ukukhetha okuthengayo.
