FCC ID:2A949-YM2022 RF EXPOSURE EVALUATION METHOD SAR Test Exclusion Thresholds for 100 MHz – 6 GHz and ≤ 50 mm Approximate SAR Test Exclusion Power Thresholds at Selected Frequencies and Test Separation Distances are illustrated in the following Table. 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 f(GHz) is the RF channel transmit frequency in GHz Power and distance are rounded to the nearest mW and mm before calculation The result is rounded to one decimal place for comparison 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. FCC ID:2A949-YM2022 BLE The Worst Case Mode 2402-2480MHz Detector PEAK BLE 2±1dBm Remark:The worst case gain of the antenna is 0.2dBi. 0.2dBi logarithmic terms convert to numeric result is nearly 1.047 2.442.0231.9952623150.62333 Limit Maximum Peak Conducted Output Power (dBm) frequency (GHz) Tune up Power (dBm) Tune up Power (mW) Result Threshold at which no SAR required is 0.6233≤ 3.0 for 1-g SAR, Separation distance is 5mm.
