This document outlines the SAR (Specific Absorption Rate) evaluation process and exclusion limits for ensuring RF (Radio Frequency) exposure compliance. It references KDB 447498, a key document providing general RF exposure guidance. The document details standalone SAR test exclusion considerations, focusing on frequency ranges from 100 MHz to 6 GHz and separation distances up to 50 mm.
The core principle involves calculating a value based on the maximum power of the channel, the minimum test separation distance, and the RF channel transmit frequency. This calculated value is then compared against numeric thresholds (3.0 for 1-g SAR and 7.5 for 10-g extremity SAR) to determine if SAR testing is required. The document also addresses scenarios with separation distances greater than 50 mm and frequencies below 100 MHz, providing alternative methods for SAR test exclusion.
Ultimately, the goal is to determine whether the device meets the SAR test exclusion limits, thereby avoiding the need for extensive SAR testing. The document includes a sample calculation and a pass/fail result based on the established criteria.
