BTF Testing Lab Specific Absorption Ratio (SAR) qhia

piav qhia luv luv:

Specific Absorption Ratio (SAR) yog hais txog cov hluav taws xob hluav taws xob hluav taws xob hluav taws xob uas nqus los ntawm ib chav tsev ntawm cov teeb meem hauv ib lub sijhawm. Thoob ntiaj teb, tus nqi SAR feem ntau yog siv los ntsuas cov nyhuv thermal ntawm lub davhlau ya nyob twg hluav taws xob. Qhov kev nqus tau tshwj xeeb, qhov nruab nrab ntawm txhua lub sijhawm 6-feeb, yog tus nqi hluav taws xob hluav taws xob hluav taws xob (watts) absorbed ib kilogram ntawm tib neeg cov ntaub so ntswg. Siv lub xov tooj hluav taws xob hluav taws xob ua piv txwv, SAR hais txog qhov sib piv ntawm cov hluav taws xob nqus los ntawm cov ntaub so ntswg ntawm lub taub hau. Qhov qis dua tus nqi SAR, qhov hluav taws xob tsawg yog nqus los ntawm lub hlwb. Txawm li cas los xij, qhov no tsis tau txhais hais tias qib SAR cuam tshuam ncaj qha rau kev noj qab haus huv ntawm cov neeg siv xov tooj ntawm tes. . Nyob rau hauv layman cov ntsiab lus, qhov tshwj xeeb nqus tus nqi yog ib qho kev ntsuas ntawm qhov cuam tshuam ntawm lub xov tooj ntawm tes hluav taws xob rau tib neeg lub cev. Tam sim no, muaj ob tus qauv thoob ntiaj teb, ib qho yog European tus qauv 2w / kg, thiab lwm qhov yog Asmeskas tus qauv 1.6w / kg. Lub ntsiab lus tshwj xeeb yog tias, siv 6 feeb raws li lub sijhawm, lub zog hluav taws xob hluav taws xob hluav taws xob nqus los ntawm txhua kilogram ntawm tib neeg cov ntaub so ntswg yuav tsum tsis pub tshaj 2 watt.

BTF tau ua tiav qhov MVG (yav tas los SATIMO) SAR xeem system, uas yog ib qho kev hloov kho tshiab raws li tus qauv SAR qub thiab ua tau raws li cov qauv tshiab thiab cov qauv thoob ntiaj teb yav tom ntej. SAR xeem system muaj cov yam ntxwv ntawm kev ntsuas ceev ceev thiab cov khoom siv siab ruaj khov. Nws kuj yog qhov feem ntau siv thiab dav lees paub SAR qhov kev sim hauv cov chaw sim thoob ntiaj teb. Lub kaw lus tuaj yeem ua SAR kuaj rau GSM, WCDMA, CDMA, walkie-talkie, LTE thiab WLAN cov khoom.
