Automatic adjustment method of mobile phone and mobile phone radiation

Abstract

The invention discloses a mobile phone and a method for automatically adjusting the radiation of the mobile phone. The mobile phone includes a radio frequency chip, a baseband chip, a proximity sensor and a power amplifier. The radio frequency chip generates radio frequency signals. The baseband chip is connected with the radio frequency chip and controls the radio frequency chip to generate radio frequency signals. The proximity sensor is connected to the baseband chip and starts when it detects the approach of a human face. The power amplifier is connected with the radio frequency chip and the baseband chip. When the proximity sensor is not activated, the baseband chip controls the power amplifier to adjust the transmission power of the radio frequency signal to the first transmission power according to the first radio frequency parameter. When the proximity sensor is activated, the baseband chip controls the power amplifier according to the second radio frequency parameter. Adjust the transmit power of the radio frequency signal to the second transmit power. The first transmit power is greater than the second transmit power. Through the above method, when the user approaches the mobile phone to talk, the transmission power of the radio frequency signal adjusted by the power amplifier can be automatically reduced, thereby reducing radiation.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a mobile phone and an automatic adjustment method for radiation of the mobile phone. Background technique [0002] With the development of mobile communication technology, mobile phones have become a necessity in people's lives. People are using mobile phones more and more frequently, and the time of using mobile phones is also increasing. As we all know, mobile phones have radiation to the human body, and as the frequency of using mobile phones is higher and the time is longer, the radiation of mobile phones to the human body is also increasing. [0003] SAR (Specific Absorption Rate) is the abbreviation of electromagnetic wave absorption ratio or specific absorption rate. The SAR value is the electromagnetic wave energy absorption ratio of mobile phones or wireless products. In layman's terms, the SAR value represents a quantification of the impact of mobile phone radiatio...
