SAR Test Exclusion Calculations
1. FCC: According to KDB 447498 D01 Mobile and Portable Devices RF Exposure
Procedures and Equipment Authorization Policies v06.
(1) Clause 4.3: General SAR test reduction and exclusion guidance
Sub clause 4.31: Standalone SAR test exclusion considerations
1) The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6GHz at test
separation distance≤5 mm are determined by:
[(max. power of channel, including tune-up tolerance, mW)/(min. test
separation, mm)]*[√f(GHz) ] ≤3.0 for 1-g SAR
[(max. power of channel, including tune-up tolerance, mW)/(min. test
separation, mm)]*[√f(GHz) ] ≤7.5.0 for 10-g SAR
