METHOD AND EQUIPMENT FOR CONTROLLING POWER AMPLIFICATION

摘要

A method and a device for controlling power amplification are provided. The method for controlling power amplification includes: outputting a voltage signal according to the state of an NE; applying the voltage signal to a grid electrode or a base electrode of at least one power amplifier transistor in a power amplifier. A device for controlling power amplification is also provided. The device includes a main control unit and a voltage control unit. The main control unit is adapted to obtain a state of an equipment, and send a voltage control signal according to the state; the voltage control unit is adapted to output a voltage signal to a grid electrode or a base electrode of a power amplifier transistor in a power amplifier unit according to the voltage control signal. Thereby, static power dissipation of the power amplifier when no RF power is output is eliminated, and the efficiency of the power amplifier is improved.
