At present, SATIMO OTA (Star, SG-24, lab room SG64, SG128) system can only support the common 4G LTE test。But with the continuous popularity of GSM, support 4G, CDMA, WCDMA, LTE multi-mode mobile phone will become the mainstream of the market. So two modules work interfere with each other in tis

The performance of the whole machine is getting more and more attention in the performance test of the mobile phone. This radiation performance reflects the final launch and receive performance of the mobile phone. There are two methods to investigate the radiation performance of the mobile phone: One is to

  Introduction SAR（Specific Absorption Rate），electromagnetic wave energy absorption ratio of cell phone or wireless product. The meaning of SAR is that the body mass of the human body is absorbed or consumed by the electromagnetic power, the unit is W/kg. Wireless communication terminal of the electromagnetic radiation is too meeting

At present, mobile phone RF performance testing are increasingly concerned about the radiation performance of the test machine. This performance reflects the radiation emitted and received the final performance of the phone. There are two ways to inspect the radiation properties of mobile phones：One is from the radiation performance of

The measurement method of electromagnetic radiation is usually related to the distance between the measuring point and the radiation source. In the case of far field and near field, the nature of the electromagnetic field is different. Therefore, it is clear that the far field and near field measurement. 1、Far
