RF High Power BroadBand Test Systems 75 ohms Attenuators
75 ohm attenuator yog ib hom attenuator npe rau nws impedance ntawm 75 ohms.
Nws yog ib qho khoom siv passive siv los tswj lub teeb liab lub zog ntawm lub voj voog, A 75 ohm attenuator tiv thaiv kev nthuav dav thiab cuam tshuam ntawm lub teeb liab, thiab tiv thaiv tsis ua haujlwm los ntawm cov teeb liab dhau.
Nws cov yam ntxwv tseem ceeb muaj xws li:
1. impedance txuam: 75 ohm yam ntxwv impedance sib tw cov yam ntxwv impedance ntawm cov teeb liab kis tau tus mob ntawm cov khoom siv video, TV tshaj tawm thiab cable TV system, yog li txo qhov kev xav thiab poob ntawm cov teeb liab kis tau tus mob.
2. Tsawg distortion: Lub attenuator tuaj yeem txo lub zog ntawm lub teeb liab yam tsis muaj kev qhia ntxiv distortion lossis teeb liab cuam tshuam.
3. Muaj kev ntseeg siab: Vim lub fact tias attenuators yog cov feem ntau passive Cheebtsam thiab tsis muaj txav qhov chaw, lawv yog heev txhim khu kev qha thiab tsis tas yuav tsum tau tu los yog hloov.
75 ohm attenuators feem ntau yog siv hauv cov ntawv hauv qab no:
1. Hauv cov xov tooj cua hauv xov tooj cua thiab cov xov tooj cua digital, nws yog siv los tswj cov teeb liab lub zog thiab txo cov teeb liab cuam tshuam thiab poob.
2. Thaum lub sij hawm tsim thiab xa cov yeeb yaj duab siab thiab cov ntsiab lus siab, tswj lub zog ntawm lub teeb liab thiab tswj kev hloov pauv zoo.
3. Hauv kev tshaj tawm xov xwm thiab TV teeb liab kis tau tus mob, cov khoom siv uas kho cov teeb liab lub zog kom phim cov teeb liab tshwj xeeb ua tiav thiab nthuav cov teeb liab ntau.
4. Hauv TV kav hlau txais xov, siv los sib npaug lub teeb liab lub zog ntawm amplifiers thiab antennas.
Qualwavemuab ntau yam kev ua haujlwm siab thiab lub zog siab coaxial 75 ohms attenuators npog qhov zaus ntawm DC ~ 3GHz, tuaj yeem sib phim nrog BNC, F-hom, thiab N-hom connectors.Lub attenuation feem ntau yog nyob ntawm 1 txog 30dB.Lub attenuators nrog High precision thiab siab zog, txhim khu kev qha zoo, cov khoom feem ntau yog raws li ROHS, tuaj yeem ua tau raws li qhov sib txawv ntawm cov neeg siv khoom.
