- Abstract
The linearity and gain of RF power amplifier are greatly affected by the quiescent working point of the amplifier. In practice, the threshold opening voltage of the power amplifier changes with the temperature rise, which leads to the change of the quiescent working current, and which makes the linearity and gain deteriorate. In this paper, two kinds of temperature compensation circuits applied to the quiescent working point of power amplifier are presented. The temperature compensation of power amplifier is realized by using temperature sensor and operational amplifier, ensure that the power amplifier can maintain good linearity and gain at different temperature, and the circuit structure is simple and easy to debug.
