FEEDFORWARD LINEARIZATION OF RF POWER AMPLIFIERS |
摘要 |
RF amplifier system (200) incorporating feedforward linearization. The system includes a digital waveform source (202) generating digital data s(t) representative of at least one analog signal. The system also includes a feedforward linearization circuit for reducing a distortion of an RF power amplifier (212). The feedforward linearization circuit includes a differential amplifier (230) arranged for generating an error signal. The error signal is determined based on a difference between the distorted RF output signal and an analog RF reference signal (229) generated from the digital data.
