For 100 MHz to 6 GHz and test separation distances≤5.0mm,the1-gand10-gSARtest exclusion thresholds aredetermined by the following: [(max. power of channel, including tune-up tolerance, mW) / (min. test separation distance, mm)]ꞏ[√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 thenearest mW and mm before calculation The result is rounded to one decimal place for comparison Here, So a SAR test is not required Mode Freque ncy (MHz) Max Power (dBm) Target power W/ tolerance (dBm) Max tune up power tolerance (dBm) Max Power (mW) Min.
