Analysis Report
Report No.: 17020969HKG-001

The Equipment Under Test (EUT) is a portable 2.4GHz Transceiver (Drone Unit) for a RC
drone operating at the frequency range of 2408-2472MHz with 1 MHz channel spacing.

The EUT is powered by 3.7V rechargeable battery. After switching on the EUT and being
paired with drone, the drone can be controlled to fly forward/backward, upward/downward
and left/ right by the controller.

Antenna Type: Internal integral antenna
Antenna Gain: 0dBi
Nominal rated field strength: 82.7dBμV/m at 3m
Maximum allowed field strength of production tolerance: +/- 3dB

According to the KDB 447498:

Based on the Maximum allowed field strength of production tolerance was 85.7dBμV/m
at 3m in frequency 2.4GHz, thus;

The EIRP = [(FS*D) ^2*1000 / 30] = 0.111mW

Conducted power = Radiated Power (EIRP) – Antenna Gain
So;

Conducted Power = 0.111mW.

The SAR Exclusion Threshold Level:
= 3.0 * (min. test separation distance, mm) / sqrt(freq. in GHz)
= 3.0 * 5 / sqrt (2.480) mW
= 9.53 mW

Since the above conducted output power is well below the SAR Exclusion threshold level,
so the EUT is considered to comply with SAR requirement without testing.
