Standalone SAR test exclusion considerations Unless specifically required by the published RF exposure KDB procedures, standalone 1-g head or body and 10-g extremity SAR evaluation for general population exposure conditions, by measurement or numerical simulation, is not required when the corresponding SAR Exclusion Threshold condition, listed below, is satisfied. 2.1.2 Limits 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 tune-up tolerance, mW)/(min. test separation distance, mm)] · [√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR, where The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and for 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 Report No.: MTEB24020104-H Page 5 of 5 2.1.3 EUT RF Exposure Measurement Data BLE GFSK Test channel Peak Output Power (dBm) Tune up tolerance (dBm) Maximum tune-up Power (dBm) Lowest(2402MHz) 0.434 0.434±1 1.434 Middle(2440MHz) 1.514 1.514±1 2.514 Highest(2480MHz) 2.241 2.241±1 3.241 Worst case: GFSK Channel Maximum Peak Conducted Output Power (dBm) Maximum tune-up Power Calculated value Exclusion threshold SAR Test Exclusion (dBm) (mW) Highest(2480MHz) 2.241 3.241 2.11 0.66 3.0 Yes .......................THE END OF REPORT.........................
