BTF Testing Lab Specific Absorption Ratio (SAR) chiyambi

Kufotokozera mwachidule:

Specific Absorption Ratio (SAR) imatanthawuza mphamvu yamagetsi yamagetsi yomwe imatengedwa ndi unit mass of matter pa nthawi ya unit. Padziko lonse lapansi, mtengo wa SAR nthawi zambiri umagwiritsidwa ntchito kuyeza kutentha kwa ma radiation osachiritsika. Kuchuluka kwa mayamwidwe, pafupifupi mphindi iliyonse ya 6, ndi kuchuluka kwa mphamvu yamagetsi yamagetsi (watts) yomwe imatengedwa pa kilogalamu imodzi ya minofu yamunthu. Kutengera ma radiation a foni yam'manja mwachitsanzo, SAR imatanthawuza kuchuluka kwa ma radiation omwe amatengedwa ndi minofu yofewa yapamutu. Kutsika kwa mtengo wa SAR, ma radiation ochepa amatengedwa ndi ubongo. Komabe, izi sizikutanthauza kuti mulingo wa SAR umagwirizana mwachindunji ndi thanzi la ogwiritsa ntchito mafoni am'manja. . M'mawu a layman, kuchuluka kwa mayamwidwe enieni ndi muyeso wa momwe ma radiation ya foni yam'manja imakhudzira thupi la munthu. Pakalipano, pali miyeso iwiri yapadziko lonse lapansi, imodzi ndi ya European standard 2w/kg, ndipo ina ndi American standard 1.6w/kg. Tanthauzo lenileni ndiloti, kutenga mphindi 6 monga nthawi, mphamvu yamagetsi yamagetsi yomwe imatengedwa ndi kilogalamu iliyonse ya minofu yaumunthu sichidzapitirira 2 watt.

BTF inayambitsa bwino makina oyesera a MVG (omwe kale anali SATIMO) SAR, omwe ndi mtundu wokonzedwanso kutengera dongosolo la SAR loyambirira ndipo limakwaniritsa miyezo yaposachedwa komanso miyezo yapadziko lonse yamtsogolo. Dongosolo loyesa la SAR lili ndi mawonekedwe a liwiro loyesa mwachangu komanso kukhazikika kwa zida. Ndiwonso njira yoyesera kwambiri komanso yodziwika bwino ya SAR m'ma laboratories apadziko lonse lapansi. Dongosololi limatha kuyesa kuyesa kwa SAR pazogulitsa za GSM, WCDMA, CDMA, walkie-talkie, LTE ndi WLAN.
