System for reducing radiation straying of higher harmonics of mobile communication terminal

The invention relates to the technical field of mobile communication terminals and particularly relates to a system for reducing the radiation straying of higher harmonics of a mobile communication terminal. According to the system, a first matching circuit is arranged and is connected with a second matching circuit through a filter or a 0-ohmic resistor, so that the radiation straying of the higher harmonics of the mobile communication terminal can be reduced; when the stray radiation of the higher harmonics does not exceed the corresponding standard, the filter can be saved, and the first matching circuit is connected with the second matching circuit through the 0-ohmic resistor; and when the stray radiation of the higher harmonics in the system exceeds the corresponding standard, the first matching circuit is connected with the second matching circuit through the filter, so that the higher harmonics are inhibited, and therefore, the performance of the mobile communication terminal is improved. 本发明涉及移动通讯终端技
