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

Worse case is as below: [2440MHz -1.00dBm（ 0.794mW）output power]

( 0.794mW /5mm) ·[√2.440(GHz)]= 0.25<3.0 for 1-g SAR

Then SAR evaluation is not required
