Introduction to RF Power Amplifier

The RF power amplifier is a power amplifier that works above 30MHz. Because of its high operating frequency, the influence of the distribution parameters of the device should be considered when designing the circuit. Impedance matching is an important and difficult point in the design of RF power amplifiers, and the design is reasonable. A stable impedance matching circuit can realize a high-bandwidth, high-power, and high-efficiency RF power amplifier. In addition to matching impedance, the design of the bias circuit can make the RF power amplifier work stably, such as power changes in high and low temperature environments Small, this is closely related to the biased temperature compensation circuit. for reference only!
