Abstract

The invention discloses a power control device for a mobile communication terminal. The power control device includes: a power amplifying unit, used to amplify the input radio frequency signal to obtain an amplified radio frequency signal; a matching and filtering unit, connected to the power amplifying unit, used to adjust the load of the mobile communication terminal Matching the load of the mobile communication terminal with the amplified radio frequency signal to obtain the output power of the mobile communication terminal, while filtering out the higher harmonics output by the power amplifying unit. Through the invention, the stability of the output power of the transmitter in the wireless communication system is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a power control device for a mobile communication terminal. Background technique [0002] In wireless communication systems, there are strict requirements on the output power of the transmitter. For example, for a cellular mobile communication system that adopts the GSM (Global System for Mobile Communications) standard, the transmit power of the mobile station is divided into several levels, and the difference between each adjacent level is 2dBm. Mobile communication systems can automatically adjust the output power according to their different environments in order to maintain the best communication status with the base station. For example, when the mobile station is far away from the base station and there are many obstacles, resulting in a large signal strength attenuation, the transmitter needs to increase the transmission power; and when the mobile station is close to t...
