Radio Frequency Testing

1. Introduction to SAR detection

SAR (Specific Absorption Rate), electromagnetic wave absorption ratio or specific absorption rate, under the action of an 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 currents, resulting in the absorption and dissipation of electromagnetic energy. Excessive electromagnetic radiation from wireless communication terminals will have a certain impact on human health. Therefore, government departments and telecommunications regulatory agencies in various countries have promulgated corresponding regulations on electromagnetic radiation to limit the electromagnetic radiation of wireless products within the safe range of human body effects.

2. Introduction of SAR laboratory

The SAR laboratory of the affiliated company of GCDC Group has introduced a sophisticated test system, which meets the SAR standard requirements of IEEE/EN and American ANSI. It is fast, accurate, safe and efficient, and can complete mobile phones, tablets, watches, wireless earphones Radiation absorption ratio of wireless terminals used within 20cm of the human body such as walkie-talkies, data collectors, electronic appliances, etc., electromagnetic fields of RFID, wireless charging and other products, hearing aid compatibility (HAC) of communication terminals such as mobile phones and tablets, and portable devices above 6G Device (mmWave or Wi-Fi 6E) power density testing.
