The MPE calculation for this exposure is shown below. The peak radiated output power (EIRP) is calculated as follows: EIRP = P + G Where, P = Power input to the antenna (mW) G = Power gain of the antenna (dBi) The numeric gain(G) of the antenna with a gain specified in dB is determined by: G = Log -1 (dB antenna gain / 10) Power density at the specific separation: S = PG/(4R 2 π) Where, S = Maximum power density (mW/cm 2 ) P = Power input to the antenna (mW) G = Numeric power gain of the antenna R = Distance to the center of the radiation of the antenna (20cm = limit for MPE) Estimated safe separation: R = √(PG / 4π) Where, P = Power input to the antenna (mW) G = Numeric power gain of the antenna R = Distance to the center of the radiation of the antenna (20cm = limit for MPE) CTK Co., Ltd.

Measure the power spectral density (which will be used for emissions mask reference) using the following procedure: a. Set the span to encompass the entire 26 dB EBW of the signal. b. Set RBW = same RBW used for 26 dB EBW measurement. c. Set VBW ≥ 3 X RBW d. Number of points in sweep ≥ [2 X span / RBW]. e. Sweep time = auto. f. Detector = RMS (i.e., power averaging) g. Trace average at least 100 traces in power averaging (rms) mode. h. Use the peak search function on the instrument to find the peak of the spectrum. 2. For the purposes of developing the emission mask, the channel bandwidth is defined as the 26 dB EBW. 3. Clear trace. 4. Trace average at least 100 traces in power averaging (rms) mode. 5. Adjust the reference level as necessary so that the crest of the channel touches the top of the emission mask. CTK Co., Ltd.
