Lub RF coaxial switch yog ib lub cuab yeej siv hauv RF thiab microwave kev sib txuas lus systems los tsim lossis hloov kev sib txuas ntawm ntau txoj kab coaxial cable. Nws tso cai rau kev xaiv ntawm ib qho kev nkag lossis tso zis tshwj xeeb los ntawm ntau txoj kev xaiv, nyob ntawm qhov kev teeb tsa xav tau.
Cov yam ntxwv hauv qab no:
1Kev hloov pauv sai: RF coaxial switches tuaj yeem hloov pauv sai ntawm ntau txoj kev teeb liab RF, thiab lub sijhawm hloov pauv feem ntau yog nyob rau theem millisecond.
2. Kev poob qis ntawm kev ntxig: Cov qauv hloov pauv yog compact, nrog rau kev poob qis ntawm lub teeb liab, uas tuaj yeem ua kom muaj kev sib kis ntawm lub teeb liab zoo.
3. Kev rho tawm siab: Lub qhov hloov pauv muaj kev rho tawm siab, uas tuaj yeem txo qhov kev cuam tshuam ntawm cov teeb liab.
4. Kev ntseeg siab siab: Lub RF coaxial switch siv cov khoom siv zoo thiab cov thev naus laus zis tsim khoom siab, uas muaj kev ntseeg siab thiab ruaj khov.
Cov khoom siv los ntawm Qualwaves Inc.RF coaxial switches nrog ntau zaus ua haujlwm ntawm DC ~ 110GHz thiab lub neej ntev txog li 2 lab lub voj voog.
Tsab xov xwm no qhia txog 2.92 hli coaxial switches rau DC ~ 40GHz thiab SP7T ~ SP8T.
