RF Exposure evaluation 1. Reference 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 and eirp = p t x g t = (E X d ) 2 / 30 Where: p t = transmitter output power in watts, g t = 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 2. Result As the antenna EUT used was 1dBi and the Max field strength (average) level measured in EMI test report, the sar exclusion value can obtained. Frequency (MHz) Field strength dBuV/m Antenna Gain (numeric) Separation Distance (mm) calculated value exclusion thresholds 2441 85.23 1.2589 5.00 0.025 3 3. Conclusion The SAR evaluation is not required.
