Linearization for power amplifiers using feed-forward and feedback control |
摘要 |
The present invention is a method and apparatus for linearizing an output signal which is generated by a power amplifier (PA). A phase compensation on the output signal is performed using a phase feed-forward path and a phase feedback path. An amplitude compensation on the output signal is performed using an amplitude feed-forward path and an amplitude feedback path. The amplitude compensation is synchronized with the phase compensation.
