Abstract
A temperature compensation circuit is configured to generate a first electrical signal corresponding to the current ambient temperature, use the first electrical signal to adjust a second electrical signal received by an electrical signal input end, and obtain a third electrical signal; and output the third electrical signal to a power control circuit. The power control circuit is configured to convert the third electrical signal into a fourth electrical signal and output the fourth electrical signal to a power amplifier. The fourth electrical signal is used for controlling the gain of the power amplifier to present a preset change rule following a temperature change. Thus, by adding the described temperature compensation circuit in a power amplification circuit, the stability of the gain and the stability of the output power of a power amplifier are ensured, and the performance of the power amplifier is not affected by a change in temperature.
