This document details the RF exposure evaluation for a portable device, adhering to FCC regulations outlined in §15.247(e)(i) and §1.1307(b)(1). The evaluation ensures that the device operates within the Commission's guidelines for radio frequency energy exposure.
The assessment follows KDB447498 D01 General RF Exposure Guidance V06, focusing on 1-g and 10-g SAR test exclusion thresholds for devices operating between 100 MHz and 6 GHz with test separation distances of ≤ 50 mm. The SAR test exclusion is determined by a formula involving the maximum power of the channel, tune-up tolerance, and the RF channel transmit frequency.
The report includes specific data for the device operating at 433.922MHz using ASK modulation. It presents conducted power, tune-up power, and calculated SAR values. The results indicate that the device meets the SAR test exclusion criteria, with a calculated value significantly below the FCC limit of 3.0 for 1g SAR. The minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion.
