KDB 447498D01 (v05r02) has the following exclusion for portable devices: The 1g and 10g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances < 50 mm are determined b y: [ (measured maximum average output power(mW))/(Minimum separation distance(mm))]•[ √ f (GHz)] < 3.0 for 1g SAR and < 7.5 for 10g 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 calculation • The result is rounded to one decimal place for comparison The test exclusions are applicable onl y 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 is applied to determine SAR test exclusion. This device f = 2.48 GHz, distance = 5mm (minimum separation distance: 5 mm was used in the calculation) and the measured maximum average output power was 5 mW So for this device: 5 mW [measured maximum avera ge output power] / 5 mm [minimum separation distance] * ( √ 2.48) = 1.6 *This is less than 3.0, so no SAR is required. Even takin g into account the tolerance, this device can be satisfied with the limits. Thank you for your attention to this matter. Go Ishiwata Site Mana ger EMC/Wireless Group, Kashima EMC Lab.
