Abstract

The invention discloses a method for controlling radiation straying and related equipment. The method is applied to an electronic device comprising a harmonic suppression circuit, and comprises the steps of determining a target environment where the electronic device is located; under the condition that the target environment is a set environment, controlling the harmonic suppression circuit to suppress first target harmonic radiation, wherein first target harmonics are all harmonics generated by the electronic device, and the set environment comprises the environment with dense human traffic;and under the condition that the target environment is not the set environment, controlling the harmonic suppression circuit to suppress second target harmonic radiation, wherein second target harmonics are the harmonics of the electronic device under the target environment for suppressing radiation in the last time. According to the method and the related equipment provided by the embodiment ofthe invention, the problem that the harmonics generated by the electronic device is prevented from affecting the other users is avoided.

Description

technical field [0001] The present application relates to the field of electronic technology, and in particular to a method for controlling stray radiation and related equipment. Background technique [0002] At present, radiation spurious, as a mandatory certification indicator for electronic devices (such as smart phones, etc.), is the most complicated and difficult problem among all certifications. Especially in the Global System for Mobile Communication (GSM) frequency band, because the power of GSM itself is high, it is easy to excite strong energy in an instant, resulting in excessive radiation of spurious harmonics. In actual engineering, the third harmonic of GSM900MHZ, the second harmonic of GSM1800MHZ or the third harmonic of GSM2700MHZ exceed the standard. Harmonics generated by electronic devices mainly affect other users. Contents of the invention [0003] Embodiments of the present application provide a method for controlling spurious radiation and related ...
