A coaxial switch is passive electromechanical relay inoshandiswa kushandura masaini eRF kubva kune imwe chiteshi kuenda kune imwe.Rudzi urwu rwekuchinja runoshandiswa zvakanyanya mumamiriro ekuisa chiratidzo anoda yakakwira frequency, simba rakawanda, uye yakakwira RF kuita.Inowanzo shandiswa muRF yekuongorora masisitimu, senge antennas, setiraiti kutaurirana, nharembozha, base zviteshi, avionics, kana mamwe maapplication anoda kushandura masaini eRF kubva kune rumwe rutivi kuenda kune rumwe.
Chinja chiteshi
NPMT: zvinoreva n-pole m-kukanda, uko n ndiyo nhamba yezviteshi zvekupinza uye m ndiyo nhamba yezviteshi zvinobuda.Semuyenzaniso, RF switch ine imwe yekupinza port uye maviri anobuda madoko anodaidzwa danda rimwechete kukanda kaviri, kana SPDT/1P2T.Kana iyo RF switch ine imwe yekupinza uye 6 zvakabuda, saka isu tinoda kusarudza SP6T RF switch.
RF maitiro
Isu tinowanzo tora zvinhu zvina mukufunga: Isa kurasikirwa, VSWR, Isolation uye Simba.
Frequency mhando:
Isu tinogona kusarudza iyo coaxial switch zvinoenderana neiyo frequency renji yehurongwa hwedu.Iyo huru frequency yatinogona kupa ndeye 67GHz.Kazhinji, isu tinokwanisa kuona kuwanda kweiyo coaxial switch zvichibva pane yayo yekubatanidza mhando.
SMA Chibatanidza: DC-18GHz/DC-26.5GHz
N Chibatanidza: DC-12GHz
2.92mm Chibatanidza: DC-40GHz/DC-43.5GHz
1.85mm Chibatanidza: DC-50GHz/DC-53GHz/DC-67GHz
SC Chibatanidza: DC-6GHz
Avhareji simba: Pazasi mufananidzo unoratidza avhareji simba db dhizaini switch.
Voltage:
Iyo coaxial switch inosanganisira electromagnetic coil uye magineti, inoda DC voltage kutyaira switch kune inoenderana RF nzira.Mhando dzemagetsi dzinowanzoshandiswa mu coaxial switches dzinotevera: 5V.12V.24V.28V.Kazhinji vatengi havashandise 5V voltage zvakananga.Isu tinotsigira sarudzo TTL yekurega yakaderera voltage se5v kudzora RF switch.
Dhiraivha mhando:
Failsafe: Kana pasina yekunze control voltage inoiswa, imwe chiteshi inogara ichiitisa.Wedzera yekunze magetsi ekupa, iyo RF chiteshi inoitwa kune imwe.Kana voltage yadzimwa, yaimbova RF chiteshi iri kuita.
Latching: Latching type switch inoda inoramba iine magetsi kuti ichengetedze inoburitsa RF chiteshi ichiitisa.Mushure mekunge magetsi anyangarika, iyo latching drive inogona kuramba iri mumamiriro ayo ekupedzisira.
Kazhinji Vhura: Iyi modhi yekushanda inongoshanda kune SPNT.Pasina iyo inodzora voltage, ese ekuchinja chiteshi haasi kuita;Wedzera simba rekunze rekupa uye sarudza chiteshi chakatsanangurwa chekuchinja;Kana iyo yekunze voltage isina kuiswa, switch inodzokera kune iyo mamiriro ayo ese machani asiri kuita.
Indicator: Iri basa rinobatsira kuratidza shanduko yemamiriro.
