Umuhuza wa SMA ni igice gikoreshwa cyane igice cya subinature RF na microwave ihuza, cyane cyane ibereye guhuza RF muri sisitemu ya elegitoronike ifite imirongo igera kuri 18 GHz cyangwa irenga.Ihuza rya SMA rifite uburyo bwinshi, igitsina gabo, igitsina gore, kigororotse, inguni iburyo, diaphragm fitingi, nibindi, bishobora kuzuza ibisabwa byinshi.Ubunini bwa ultra ntoya nayo iyemerera gukoreshwa, ndetse no mubikoresho bya elegitoroniki bito.
1 Intangiriro kuri SMA umuhuza
Ubusanzwe SMA ikoreshwa mugutanga RF ihuza imbaho zumuzunguruko.Ibice byinshi bya microwave birimo gushungura, attenuator, kuvanga na oscillator.Umuhuza afite urudodo rwo hanze rwihuza, rufite ishusho ya hexagon kandi rushobora gukomera hamwe na wrench.Birashobora gukomera kumurongo ukwiye ukoresheje umurongo wihariye wa torque, kugirango ihuriro ryiza rishobore kugerwaho bitarenze gukomera.
Ihuza rya mbere rya SMA ryashizweho kuri 141 kabili ya kabili ya coaxial.Ihuza ryambere rya SMA rishobora kwitwa umuhuza muto, kubera ko rwagati rwumugozi wa coaxial rugizwe na pin rwagati rwihuza, kandi nta mpamvu yo guhinduka hagati yumuyobozi wa coaxial centre na pin hagati ya connexion idasanzwe.
Akarusho kayo nuko umugozi wa dielectric uhujwe neza na interineti nta ntera y’ikirere, kandi ibibi byayo ni uko hashobora gukorwa umubare muto gusa wo guhuza / guhagarika.Nyamara, kuri porogaramu ukoresheje insinga ya kabili ya coaxial, ibi ntibishoboka ko biba ikibazo, kuko ubusanzwe ibyashizweho nyuma yo guterana kwambere.
2 、 Imikorere ya SMA umuhuza
Umuhuza wa SMA wagenewe kugira impedance ihoraho ya 50 oms kuri umuhuza.Ihuza rya SMA ryakozwe mbere kandi ryagenewe imirimo igera kuri 18 GHz, nubwo verisiyo zimwe zifite inshuro zo hejuru za 12.4 GHz naho verisiyo zimwe zashyizweho nka 24 cyangwa 26.5 GHz.Imipaka yo hejuru yo hejuru irashobora gusaba gukora hamwe nigihombo kinini cyo kugaruka.
Muri rusange, abahuza SMA bafite kwigaragaza cyane kurenza abandi bahuza kugeza 24 GHz.Ibi biterwa ningorabahizi mugukosora neza inkunga ya dielectric, ariko nubwo bigoye, abayikora bamwe bashoboye gutsinda neza iki kibazo kandi barashobora kugena abahuza kubikorwa bya 26.5GHz.
Ku nsinga zoroshye, imipaka yumurongo isanzwe igenwa numuyoboro aho guhuza.Ibi ni ukubera ko abahuza SMA bemera insinga nto cyane, kandi igihombo cyabo mubisanzwe kirenze kure ibyo guhuza, cyane cyane mubihe bashobora gukoresha.
3 power Imbaraga zagereranijwe za SMA umuhuza
Rimwe na rimwe, igipimo cyihuza SMA gishobora kuba ingenzi.Ikintu cyingenzi kugirango umenye ubushobozi bwikigereranyo cyo gukoresha imbaraga za shaft ihuza ni uko ishobora kwanduza umuyaga mwinshi kandi bigatuma ubushyuhe buzamuka mubushyuhe buringaniye.
Ingaruka yo gushyushya iterwa ahanini no kurwanya guhura, nigikorwa cyubuso bwubuso bwuburyo nuburyo amakariso ahurira hamwe.Agace k'ingenzi ni ihuriro hagati, rigomba kuba ryarakozwe neza kandi rigashyirwa hamwe.Twabibutsa kandi ko impuzandengo yagereranijwe igabanuka hamwe ninshuro kuko igihombo cyo guhangana cyiyongera hamwe ninshuro.
Amashanyarazi atunganya amakuru ya SMA ahuza aratandukanye cyane mubakora, ariko imibare imwe yerekana ko bamwe bashobora gutunganya watt 500 kuri 1GHz hanyuma bakamanuka kuri munsi ya 200 watt kuri 10GHz.Nyamara, iyi nayo ni amakuru yapimwe, ashobora kuba mubyukuri.
Kuri SMA microstrip ihuza ifite ubwoko bune: ubwoko butandukana, ubwoko bwa TTW bwicyuma, Ubwoko bwa Medium TTW, guhuza ubwoko butaziguye.Nyamuneka kanda kuri:https://www.dbdesignmw.com/microstrip-umuhuza-hitamo-table/guhitamo imwe.
