Analysis Report Report No.: 19031210HKG‐001 The Equipment Under Test (EUT), is a portable 2.4GHz Transceiver (Controller Unit) for a RC plane. The operation frequency range is between 2412MHz and 2472MHz with 61 channels. The channel is separated by 1 MHz channel spacing. The EUT is powered by DC 3.0V (2 x 1.5V AAA batteries). After switch on the EUT, the plane will be moved forward, backward, upward, downward, left and right based on the switches pressed in the controller. Antenna Type: Internal, Integral Antenna Type: Internal integral antenna Antenna Gain: 0dBi Nominal rated field strength (Peak): 102.5dBμV/m at 3m Nominal rated field strength (Average): 70.1dBμV/m at 3m Maximum allowed field strength of production tolerance: +/- 3dB According to the KDB 447498: Based on the average allowed field strength of production tolerance was 73.1dBμV/m at 3m. Thus, it below calculated field strength according to minimum SAR exclusion threshold level as follows: The worst case of SAR Exclusion Threshold Level: = 3.0 * (min. test separation distance, mm) / sqrt(freq. in GHz) = 3.0 * 5 / sqrt (2.4835) mW = 9.52 mW According to the KDB 412172 D01: EIRP = [(FS*D) ^2*1000 / 30] Calculated Field Strength for 9.52mW is 105dBuV/m at 3m Since average field strength plus production tolerance < = 105dBuV/m at 3m and antenna gain is > = 0.0dBi, it is concluded that maximum Conducted Power and Field Strength are well below the SAR Exclusion threshold level, so the EUT is considered to comply with SAR requirement without testing.
