SAR REFERENCE WAVEGUIDE CALIBRATION REPORT Ref: ACR.262.12..MVGB.A 1 INTRODUCTION This document contains a summary of the requirements set forth by the IEEE 1528 and CEI/IEC 62209 standards for reference waveguides used for SAR measurement system validations and the measurements that were performed to verify that the product complies with the fore mentioned standards. 2 DEVICE UNDER TEST Device Under Test Device Type COMOSAR 5000-6000 MHz REFERENCE WAVEGUIDE Manufacturer MVG Model SWG5500 Serial Number SN 13/14 WGA32 Product Condition (new / used) Used A yearly calibration interval is recommended. 3 PRODUCT DESCRIPTION 3.1 GENERAL INFORMATION MVG’s COMOSAR Validation Waveguides are built in accordance to the IEEE 1528 and CEI/IEC 62209 standards. 4 MEASUREMENT METHOD The IEEE 1528 and CEI/IEC 62209 standards provide requirements for reference waveguides used for system validation measurements. The following measurements were performed to verify that the product complies with the fore mentioned standards. 4.1 RETURN LOSS REQUIREMENTS The waveguide used for SAR system validation measurements and checks must have a return loss of -8 dB or better. The return loss measurement shall be performed with matching layer placed in the open end of the waveguide, with the waveguide and matching layer in direct contact with the phantom shell as outlined in the fore mentioned standards. 4.2 MECHANICAL REQUIREMENTS The IEEE 1528 and CEI/IEC 62209 standards specify the mechanical dimensions of the validation waveguide, the specified dimensions are as shown in Section 6.2. Figure 1 shows how the dimensions relate to the physical construction of the waveguide.
