摘要：A pseudo-envelope tracking modulated power supply system, which is used to
provide a power amplifier supply voltage to a radio frequency power amplifier, isdisclosed. In a first embodiment, during a high power modulation mode and a mediumpower modulation mode, the power amplifier supply voltage provides envelope tracking.During a low power average power tracking mode, the power amplifier supply voltageprovides average power tracking. In a second embodiment, an output power from theradio frequency power amplifier is regulated based on a difference between a targetoutput power from the radio frequency power amplifier and a measured output powerfrom the radio frequency power amplifier. The power amplifier supply voltage providespower for amplification, based on the difference between the target output power andthe measured output power.
