This analysis report focuses on a portable 2.4GHz Transceiver, specifically a Car Unit designed for a Radio Controlled (RC) car. The device operates across 33 channels within the 2420-2465MHz frequency range. Power is supplied by two 3.2V Lithium-ion batteries, enabling forward, backward, left, and right movement based on controller inputs.
The report details the antenna type as an internal integral antenna with 0dBi gain. The nominal rated field strength is measured at 62.8dBμV/m at 3m (Average), with a production tolerance of +/- 3dB. The analysis adheres to KDB 447498 D04 Interim General RF Exposure Guidance v01, calculating field strength against SAR exclusion thresholds.
Calculations are performed to determine compliance with SAR exclusion thresholds, considering factors like frequency, distance, and ERP. The report concludes that the maximum conducted power and field strength are below the SAR Exclusion threshold level, indicating compliance without requiring further testing.
