RF EXPOSURE ANALYSIS Product FCC ID MGM13P12 802.15.4/BT5.0 Module QOQMGM13 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 tun-up tolerance, mW)/(min. separation distance, mm.)]* (√f(GHz))≤3 For MGM13P12 the maximum peak TX power including tolerances is 100 mW for the Zigbee and 72.8mW for the Bluetooth. The maximum duty cycle of Zigbee is 66% and the duty cycle relaxation can be calculated by 10*log(0.66)=-1.8dB. For the BT the maximum duty cycle is 98% and similarly the duty cycle relaxation is 10*log(0.98)=-0.09 dB. Thus, the maximum TXP including tolerances is 71.53 mW and maximum TX frequency is 2.48 GHz. Using separation distance of 38 mm with the formula above results  71.53mW     2.48  2.96  3  38mm  Thus MGM13P12 meets the SAR exclusion criteria with 38 mm separation and SAR evaluation is not needed.
