SAR & HAC MEASUREMENT SYSTEMS PRODUCT OVERVIEW

he multiplication of consumer mobile telecommunication equipment (MTE) has raised concerns about potential adverse health effects due to electromagnetic field exposure. For radio frequency safety purposes, international regulatory bodies and committees have elaborated standards to which MTE should comply. MVG offers a range of Specific Absorption Rate (SAR) and Hearing Aid Compatibility (HAC) measurement systems for the test and certification of MTE. W hy do we measure SAR values? The radio frequency (RF) energy radiated by MTE is absorbed in the body and produces heat, which is carried...

H ow do we measure SAR values? The SAR values are complex to measure as the penetration of energy within human tissues depends on many factors, such as the type of the phone, the shape of the user’s head or the frequency. For this reason, SAR measurements are performed in laboratory using specific instrumentation defined in the standards: head phantom, liquid, E-field probe… The measurement process consists in using a scanning system to measure the internal E-field distribution in a phantom model filled with liquid. The shape of the head and the liquids simulate the human head and tissue....

About Microwave Vision Group (MVG) Since its creation in 1986, The Microwave Vision Group (MVG) has developed a unique expertise in the visualization of electromagnetic waves. These waves are at the heart of our daily lives: Smartphones, computers, tablets, cars, trains, planes - none of these devices and vehicles would work without them. Year after year, the Group develops and markets systems that allow for the visualization of these waves, while evaluating the characteristics of antennas, and helping speed up the development of products using microwave frequencies. The Group’s mission is...
