Linear RF amplifier with polar feedback |
摘要 |
A system for power amplification of an RF signal including polar feedback control. The system may include a feedback-controlled modulator configured to modulate an RF signal based on a feedback-corrected control signal. The modulator is further configured to generate a modulated RF signal. The system also may include a phase shifter configured to correct the phase of the modulated RF signal based on a feedback phase control signal. The system further includes a power amplifier in communication with the modulator and/or the phase shifter. The amplifier is configured to amplify the modulated RF signal and to generate an amplified RF output signal. The system also includes a feedback network configured to generate polar feedback signals, including the feedback-corrected control signal and/or the feedback phase control signal.
