 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 tunc—up tolerance, mW)(min. test separation distance,
mm}] + [/f(GHz)] < 3.0 for 19 SAR and < 7.5 for 10—g extremity SAR,where
i(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 only when the minimum test separation distance is < 50
mm and tor 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
