Antenna Type: Internal, Integral antenna Antenna Gain: 0dBi Nominal rated field strength is 98.3dBμV/m at 3m (Peak), 86.0dBμV/m at 3m (Average) Maximum allowed production tolerance: +/- 3dB The brief circuit description is listed as follows: 1. U1 acts as MCU 2. U1 (H04J28B) act as RF Module 3. U3 acts as BLE Module 4. U5 (GPY0030C) acts as audio circuit. 5. Y1 acts as 24MHz Oscillator 6. C2, L1 and L2 act as antenna matching circuit 7. Q1 acts as amplifier.

Analysis Report The Equipment Under Test (EUT), is a portable 2.4GHz BR/EDR Transceiver (Keyboard Unit) for a Bluetooth keyboard. The sample supplied operated on 79 channels, normally at 2402 - 2480MHz. The channels are separated with 1MHz spacing. The EUT is powered by 3 x 1.5V AA batteries. After switching on the EUT, the keyboard will be playing songs based on the paired smartphone. Antenna Type: Internal, Integral antenna Antenna Gain: 0dBi Nominal rated field strength is 98.3dBμV/m at 3m (Peak), 86.0dBμV/m at 3m (Average) Maximum allowed production tolerance: +/- 3dB According to the KDB 447498: Based on the maximum average field strength of production tolerance was 89.0dBμV/m at 3m in frequency 2.440GHz. 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 (2.483.5) 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 @3m Since maximum average field strength plus production tolerance < = 105dBuV/m @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.
