COMPENSATION CIRCUIT MODULE, POWER AMPLIFICATION ASSEMBLY, COMPENSATION METHOD, AND DEVICE

WIPO Patent Application WO/2023/019812

A1

Embodiments of the present disclosure relate to a compensation circuit module, a power amplification assembly, a compensation method, and a device. The compensation circuit module at least comprises a variable resistor, a detection assembly, and a control assembly. A detection end of the detection assembly is connected to a DC blocking capacitor of a power amplifier, and is configured to detect a voltage swing of an input signal of the DC blocking capacitor. The control assembly is connected to the detection assembly and is configured to output a control signal according to the input signal detected by the detection assembly. The variable resistor is connected to an output end of the control assembly and is configured to change a resistance value connected to the power amplifier according to the control signal. The resistance value of the variable resistor connected to the power amplifier is configured to constitute a feedback resistance value of the power amplifier. The feedback resistance value is configured to increase in the case that a gain of the power amplifier decreases. An increased feedback resistance value is configured to kept the gain at a straight section of a gain variation curve.
