Analysis for FCC, portable use
Standalone SAR test exclusion considerations are defined in the KDB 447498 Chapter 4.3.1.
1-g head or body SAR exclusion threshold is defined with formula
[(max . power of channel, including tune-up tolerance, mW)/(min. separation distance,
mm.)]* (√f(GHz))≤3
For BGM11S1A / BGM112A the absolute maximum TXP including tolerances 11.2 mW and
maximum TX frequency is 2.48 GHz. Using separation distance of 6 mm with the formula
above results
 11.22mW 

  2.48  2.95  3
 6mm 
Thus BGM121 / BGM123 meets the SAR exclusion criteria with 6 mm separation. If the
separation distance to human body is 6mm or more then SAR evaluation is not needed.
Worst case SAR has been measured and the SAR test report has been provided. At
separation distance of 5mm the worst-case SAR result was 0.22 W/kg in body worn
condition. Thus, in body worn applications, further SAR testing is not needed and the module
can be placed in touch with human body.
