A radio frequency (RF) power amplifier is an electronic device used to amplify a signal to a higher power level. It is usually used to increase the power of a radio frequency signal so that it can be transmitted over a greater distance, with better reception quality.

RF power amplifiers are used in a variety of applications, such as for radio and television transmission, satellite and wireless communications, and medical and industrial equipment. RF power amplifiers are also used in military and aerospace communications systems.
