RF Exposure evaluation According to 447498 D01 General RF Exposure Guidance v05 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 calculation The result is rounded to one decimal place for comparison eirp = pt x gt = (EXd) 2 /30 where: pt = transmitter output power in watts, gt = numeric gain of the transmitting antenna (unitless), E = electric field strength in V/m, --- 10 ((dBuV/m)/ 20) /10 6 d = measurement distance in meters (m)---3m So pt = (EXd) 2 /30 x gt Field strength = 89.76 dBuV/m @3m Ant gain =-2.0dBi; so Ant numeric gain= 0.631 So pt= {[10 ( 89.76 /20) /10 6 x3] 2 /30x0.631 }x1000 mW =0.45mW So (0.45mW/5mm)x √ 2.474GHz = 0.14 <3 Then SAR evaluation is not required
