According to KDB 447498 D01 Mobile Portable RF Exposure v05r02, no SAR required if power is lower than the flowing threshold: The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ” 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] [¥f(GHz)] ” 3.0 for 1-g SAR and ” 7.5 for 10-g extremity SAR, where • f(GHz) is the RF channel transmit frequency in GHz • Power and distance are rounded to the nearest mW and mm before calculation25 • The result is rounded to one decimal place for comparison • 3.0 and 7.5 are referred to as the numeric thresholds in the step 2 below The test exclusions are applicable only when the minimum test separation distance is ” 50 mm and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm according to 5) in section 4.1 is applied to determine SAR test exclusion. 3.Calculation method [(max. power of` channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] ·[¥f(GHz)] ” 3.0 Conducted Power + tune up tolerance = 0.67mW Distance = 5 mm f = 2.402 GHz [0.67/5] * SQRT(2.402) =0.201 0.201 ” 3.0 Therefore, excluded from SAR testing.
