Problems solved by technology

[0003] At present, some mobile communication terminals on the market do not have the temperature compensation function of radio frequency performance parameters. Some terminals use dedicated chips to realize this function, which is too expensive to be popularized. Some terminals use other principles but cannot achieve it during the compensation process. Accuracy requirements

Abstract

A mobile communication terminals RF performance adaptive temperature compensation device, including RF modules, analog baseband modules, digital baseband modules, as well as temperature detection module; temperature detection module contains DC Power Supply, the precision series resistor and thermistor, also includes and with the stated thermistor the elimination of the voltage ripple module; a mobile communication terminals RF performance adaptive temperature compensation method, the temperature will be calculated DAC value and the temperature compensation terminal comparison table, calculated on the RF transmitter power and receiver gain compensation value and realize the RF parameters of temperature compensation. This invention using thermistor, high-precision resistors with terminal software-controlled methods, the environmental temperature can be achieved automatically detect, judgment, and in accordance with the terminal RF performance parameters expected accurate target compensation to enable terminals to meet the national standard of technical indicator.

Description

technical field [0001] The invention relates to radio frequency technology of mobile communication, in particular to a method and device for self-adaptive compensation of radio frequency performance temperature of a mobile communication terminal. Background technique [0002] According to the national standard GB2423.1-89 "Basic Environmental Test Regulations for Electrical and Electronic Products" and the national mobile communication industry standards of various formats, there are clear technical index requirements for the RF performance of mobile terminals under normal and extreme temperature conditions, which is It is required that the mobile terminal must have the functions of automatic detection, automatic judgment and automatic compensation for the ambient temperature, that is, it must have good environmental adaptability. [0003] At present, some mobile communication terminals on the market do not have the temperature compensation function of radio frequency perfor...
