RF Exposure report

The Equipment Under Test (EUT) is a Bluetooth Module with Bluetooth function
operating at 2402-2480MHz, 40 channels with 2MHz channel spacing. The EUT
was powered by DC 3.8V. For more detailed features description, please refer to
the user’s manual.

Antenna Type: Integral antenna.
Antenna Gain: 1.0dBi
Modulation Type: GFSK.
The nominal conducted output power specified: -5.4 dBm +/-3dB.
The nominal radiated output power (EIRP) specified: -4.4dBm +/-3dB.

The maximum tested radiated output power for the EUT is -1.43dBm in the
frequency 2.402GHz which is within the production variation.

The minimum tested radiated output power for the EUT is -2.33dBm in the
frequency 2.440GHz mode which is within the production variation.

According to the KDB 447498, the simple calculation as below:

The maximun conducted output power specified is -1.4 dBm = 0. 7 mW
The source- based time-averaging conducted output power
= 0.7 * Duty Cycle mW = 0. 7 mW

The SAR Exclusion Threshold Level:
= 3.0 * (min. test separation distance, mm) / sqrt(freq. in GHz)
= 3.0 * 5 / sqrt (2.480) mW
= 9.5 mW

Since the source-based time-averaging conducted output power is well
below the SAR low threshold level, so the EUT is considered to comply
with SAR requirement without testing.

Transmitter Duty Cycle Calculation
The test signal of the EUT is Continuous emission, so the Duty Cycle is
100%.
