SMA connector inowanzoshandiswa semi precision subminiature RF uye microwave connector, kunyanya yakakodzera RF yekubatanidza mumagadzirirwo emagetsi ane mafrequency anosvika 18 GHz kana kutokwira.SMA ma-connectors ane akawanda mafomu, echirume, chikadzi, akatwasuka, ekona yekurudyi, diaphragm fittings, nezvimwe, izvo zvinogona kusangana nezvakawanda zvinodiwa.Yayo yekupedzisira diki saizi inobvumirawo kuti ishandiswe, kunyangwe mune zvidiki zvigadzirwa zvemagetsi.
1, Nhanganyaya kuSMA connector
SMA inowanzo shandiswa kupa RF kubatana pakati pemabhodhi edunhu.Zvizhinji zve microwave zvikamu zvinosanganisira mafirita, attenuators, musanganiswa uye oscillator.Iyo yekubatanidza ine shinda yekunze yekubatanidza interface, iyo ine hexagon chimiro uye inogona kusimbiswa nechipanera.Ivo vanogona kusimbiswa kune chaiyo tightness vachishandisa yakakosha torque wrench, kuitira kuti kubatana kwakanaka kugone kuwanikwa pasina kuwedzera kuomesa.
Yekutanga SMA yekubatanidza yakagadzirirwa 141 semi-rigid coaxial tambo.Iyo yepakutanga SMA yekubatanidza inogona kunzi diki yekubatanidza, nekuti pakati peiyo coaxial tambo inoumba yepakati pini yekubatanidza, uye hapana chikonzero chekuchinja pakati peiyo coaxial centre conductor uye yepakati pini yeyakakosha yekubatanidza.
Kubatsira kwaro ndekwekuti tambo dielectric yakabatana zvakananga kune iyo interface isina mhepo gap, uye iyo yakashata ndeyokuti chete nhamba shoma yekubatanidza / yekubvisa mitsetse inogona kuitwa.Nekudaro, kune maapplication anoshandisa semi-rigid coaxial tambo, izvi hazvigone kuve nyaya, sezvo kuisirwa kunowanzo gadziriswa mushure mekutanga kusangana.
2. Kuita kweSMA connector
Iyo SMA yekubatanidza yakagadzirirwa kuve nekusingaperi impedance ye50 ohms pane chinongedzo.SMA connectors zvakagadzirirwa uye zvakagadzirirwa kushanda kusvika 18 GHz, kunyange zvazvo dzimwe shanduro dzine yepamusoro 12.4 GHz uye dzimwe shanduro dzakasarudzwa se 24 kana 26.5 GHz.Yepamusoro yepamusoro frequency miganho ingangoda kushanda nekurasikirwa kwekudzoka kwepamusoro.
Kazhinji, maSMA ma-link ane yepamusoro-soro kuratidza kupfuura mamwe ma-link anosvika 24 GHz.Izvi zvinokonzerwa nekuoma kwekunyatsogadzirisa kutsigirwa kwedielectric, asi pasinei nekuoma uku, vamwe vagadziri vakakwanisa kukunda dambudziko iri uye vanokwanisa kusarudza zvibatanidza zvavo zvekushanda kwe26.5GHz.
Kune tambo dzinochinjika, iyo frequency muganho inowanzotemwa netambo kwete yekubatanidza.Izvi zvinodaro nekuti SMA majoini anogashira tambo diki kwazvo, uye kurasikirwa kwavo kwakakura zvakanyanya kupfuura izvo zvekubatanidza, kunyanya muhuwandu hwavanogona kushandisa.
3, Yakayerwa simba reSMA connector
Mune zvimwe zviitiko, chiyero cheSMA chinongedzo chingave chakakosha.Iyo yakakosha paramende yekuona avhareji simba rekubata simba reiyo mating shaft yekubatanidza ndeyekuti inokwanisa kufambisa yakakwira ikozvino uye kuchengetedza kupisa kukwira kune imwe tembiricha.
Mhedzisiro yekudziya inonyanya kukonzerwa nekupokana kwekubatana, iyo ibasa renzvimbo yekusangana uye nzira iyo mapedhi ekusangana ari pamwechete.Nzvimbo yakakosha ndeyekusangana kwepakati, iyo inofanirwa kuumbwa zvakanaka uye yakanyatsobatanidzwa pamwe chete.Izvo zvinofanirwa kucherechedzwa kuti avhareji yakayerwa simba inodzikira ne frequency nekuti kurasikirwa kwekupokana kunowedzera ne frequency.
Iyo simba rekugadzirisa data yeSMA yekubatanidza inosiyana zvakanyanya pakati pevagadziri, asi mamwe manhamba anoratidza kuti vamwe vanogona kugadzirisa mazana mashanu watts pa1GHz uye kudonha kusvika zvishoma pasi pe200 watts pa10GHz.Nekudaro, iyi zvakare ndiyo yakayerwa data, iyo inogona kunge yakakwira chaizvo.
Kune SMA microstrip yekubatanidza ine mhando ina: inobviswa mhando, simbi TTW mhando, Medium TTW mhando, yakananga kubatanidza mhando.Ndapota tinya pa:https://www.dbdesignmw.com/microstrip-connector-selection-table/kusarudza imwe yekutenga.
