Abstract
A temperature compensation bias circuit is provided, including a third resistor, a fourth resistor, a fifth resistor, a sixth resistor, a seventh resistor, a second capacitor, a third capacitor, a fifth capacitor, a fifth transistor, a sixth transistor, and a seventh transistor. A power amplifier is further provided, the power amplifier applies the temperate compensation bias circuit. Compared with the prior art, there are fewer effects on a bias point of the temperature compensation bias circuit when the temperature compensation bias circuit and the power amplifier are in RF operating states, the power amplifier is enabled to have good temperature compensation effect and high linearity.
