Introduction to SAR testing

It is defined as: under the action of external electromagnetic field, an induced electromagnetic field will be generated in the human body. Since various organs of the human body are lossy media, the electromagnetic field in the body will generate current, resulting in the absorption and dissipation of electromagnetic energy. SAR is commonly used in biological dosimetry to characterize this physical process. The meaning of SAR is the electromagnetic power absorbed or consumed by unit mass of human tissue, in W/kg.

The LCS SAR laboratory supports SAR testing of mobile devices such as mobile phones, data cards, tablets, and walkie-talkies. The test frequency range is 300MHz-6GHz, including 2G, 3G, 4G, WIFI and other communication standards.
