RF Exposure Requirements

Product Description: TABLET PC
Model No.: F_7HD4CORE

According to the KDB 447498 D01 v06 section 4.3.1, for 100 MHz to 6 GHz and test separation
distances ≤ 50 mm, the 1-g and 10-g SAR test exclusion thresholds are determined by the
[(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance,
mm)] ꞏ [√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR, where
- f(GHz) is the RF channel transmit frequency in GHz
- Power and distance are rounded to the nearest mW and mm before calculation17
- The result is rounded to one decimal place for comparison

Calculation Result:

Tx frequency range: 2412-2462MHz
Min. test separation distance: 5mm
Maximum Conducted Output Power: 9.73dBm
Tune-Up output power: 9.5dBm
RF channel transmit frequency: 2437MHz
Result: 2.9
Limit: 3.0

Tx frequency range: 2402-2480MHz
Min. test separation distance: 5mm
Maximum Conducted Output Power: 2.88dBm
Tune-Up output power: 3dBm
RF channel transmit frequency: 2480MHz
Result: 0.6
Limit: 3.0

BT and Wi-Fi can’t transmit at the same time. So the transmitter complies with the RF exposure
requirements and the SAR is not required.
