用于连续性宽温的射频链路增益自动补偿方法及装置

By acquiring the voltage output of the temperature compensation unit and controlling its switching, a phase shifter is used to achieve automatic gain compensation over a wide temperature range for the RF link. This solves the problem of limited gain compensation range in the existing technology and achieves refined gain compensation and low power consumption over a wide temperature range.

AI Technical Summary

Technical Problem

Existing technologies struggle to achieve precise compensation of RF link gain over continuously varying temperature values ​​without increasing the size of the core circuitry of the phase shifter-based RF link.

Method used

By acquiring a first voltage that changes with a positive slope of temperature and a second voltage that changes with a negative slope of temperature, the switching of these voltages is controlled to form a control voltage, and automatic wide-temperature gain compensation of the RF link is achieved based on a phase shifter.

Benefits of technology

It achieves precise compensation of RF link gain without increasing the size of the phase shifter core circuit, reducing costs and power consumption, and providing a wider gain compensation range and more obvious effects.
