Abstract

The invention provides a wireless communication device. The wireless communication device comprises a WIFI antenna, a power amplifier, a WIFI transmitting and receiving chip and a central processing unit. The power amplifier is electrically connected between a duplexer and the WIFI transmitting and receiving chip. The WIFI transmitting and receiving chip is electrically connected with the central processing unit and used for detecting the received signal strength indication of a current WIFI signal. The central processing unit is used for controlling the output power of the WIFI transmitting and receiving chip according to the received signal strength indication of the WIFI signal transmitted by the WIFI transmitting and receiving chip, and the gain of the power amplifier is further controlled through the WIFI transmitting and receiving chip. The wireless communication device can adjust the transmitting efficiency of the WIFI antenna effectively.

Description

technical field [0001] The present invention relates to a wireless communication device, in particular to a wireless communication device with a wireless fidelity (wireless fidelity, WIFI) communication function. Background technique [0002] At present, WIFI antennas have become the standard configuration of smart wireless communication terminals. Users can use WIFI antennas to realize functions such as surfing the Internet and video. However, most of the existing WIFI antennas cannot adjust the transmission power. When the WIFI antenna works for a long time, the smart wireless communication terminal often generates heat, and causes a sharp drop in battery power. Contents of the invention [0003] In view of the above, it is necessary to provide a wireless communication device capable of adjusting the transmission power of the WIFI antenna. [0004] A wireless communication device, which includes a WIFI antenna, a power amplifier, a WIFI transceiver chip and a central pr...
