INTERTEK TESTING SERVICES
RF Exposure
The equipment under test (EUT) is a R/C Car operating at 2.4G Band. The EUT
can be powered by DC4.5V (3 x 1.5V AAA batteries). For more detail information
pls. refer to the user manual.
Antenna Type: Integral antenna.
Antenna Gain: 0dBi.
The normal radiated output power (e.i.r.p) is: -22.0dBm (tolerance: +/- 3dB).
The normal conducted output power is -22.0dBm (tolerance: +/- 3dB).
Modulation Type: GFSK.
According to the KDB 447498:
The Maximum peak radiated emission for the EUT is 73.1dBµV/m at 3m in
the frequency 2402MHz
The EIRP = [(FS*D) ^2 / 30] mW = -22.13dBm
which is within the production variation.
The Minimum peak radiated emission for the EUT is 72.1dBµV/m at 3m in
the frequency 2480MHz
The EIRP = [(FS*D) ^2 / 30] mW = -23.13dBm
which is within the production variation.
The maximum conducted output power specified is -19dBm = 0.013mW
The source- based time-averaging conducted output power
= 0.013* Duty cycle mW <0.013 mW(Duty cycle <100%)
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 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.
The duty cycle is simply the on-time divided by the period:
The duration of one cycle = 15.1884ms
Effective period of the cycle = 2.5507ms
DC =2.5507ms / 15.1884ms =0.1679 or 16.79%
