A radio-frequency power amplifier (RF power amplifier) is a type of electronic amplifier that converts a low-power radio-frequency signal into a higher-power signal. Typically, RF power amplifiers drive the antenna of a transmitter. Design goals often include gain, power output, bandwidth, power efficiency, … Ver mais Many modern RF amplifiers operate in different modes, called "classes", to help achieve different design goals. Some classes are class A, class AB, class B, class C, which are considered the linear amplifier classes. In … Ver mais Modern RF power amplifiers use solid-state devices, predominantly MOSFETs (metal–oxide–semiconductor field-effect transistors). The earliest MOSFET-based RF amplifiers date … Ver mais • FET amplifier • Power electronics Ver mais The basic applications of the RF power amplifier include driving to another high-power source, driving a transmitting antenna and exciting microwave cavity resonators.
