RF power control device

Abstract

The invention is concerned with a kind of radio frequency power control equipment. It sets on high output moving communication terminal, such as long-distance information dispose terminal, watches on inner temperature of equipment and control the power level on the 1 power level with AMPS mode to limit the calorific radio frequency power control equipment of accessorial component. The radio frequency power in this invention relates to temperature sensor to induce inner temperature of high output moving communication terminal, HDET part to induce sent power of the said moving communication terminal, a communication accepting temperature signal of the said temperature sensor and power value of the said HDET part to control the power, compare the inner temperature and set limit temperature to adjust the send power.

Description

technical field [0001] The invention relates to a radio frequency (RF: Radio Frequency) power control device, in particular to a radio frequency power control device for a high-output mobile communication terminal. Background technique [0002] Generally, for mobile communication terminals using CDMA (Code Division Multiple Access: Code Division Multiple Access), in the process of performing base station and gain control communication, even if the communication is performed at the maximum output, it will not cause overheating. Caused abnormalities in function. [0003] However, for mobile communication terminals that communicate with high output, depending on the usage environment, the chip set environment of the product may overheat. Within the range, normal performance cannot be guaranteed, and abnormal operation may occur when the above high-output mobile communication terminal is used in summer or in high-temperature / high-humidity areas. [0004] That is, the temperatu...

AI Technical Summary

Problems solved by technology

[0014] However, this existing radio frequency (RF: Radio Frequency) power control device 100 is difficult to set simply by software and hardware, so it is limited by many problems in use.

[0015] First, there is the problem of setting the temperature value of the switching action

[0016] Second, the problem of overshoot occurs when the above-mentioned power delay mode (Power back mode) operates

[0017] Third, when the cut-off action of the switch is on / off point, it is necessary to perform two signal calibration (Calibration) actions, which brings inconvenience to use

[0019] However, the above-mentioned method of using a temperature sensor to cut off the power supply is mainly applicable to broadcasters or base station equipment, and it is difficult to apply to high-output mobile communication terminals such as the above-mentioned telematics terminals.
