This second edition of the highly acclaimed RF Power Amplifiers has been thoroughly revised and expanded to reflect the latest challenges associated with power transmitters used in communications systems. The drawn-out bias current is input to a base of a transistor Q 13 via an attenuation filter F 2 and is output from an emitter of the transistor Q 13 in the state where the voltage thereof is reduced by a level corresponding to Vbe. antenna line. 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. The power amplifier operates with high efficiency at the saturated output power, maintains high linearity with enhanced efficiency at back-off power levels, and covers a broadband frequency response. An RF amplifier is usually optimized to have high-efficiency, high-output power compression.
