摘要：
A radio frequency (RF) power amplifier (PA) and an envelope tracking power supply are disclosed. The RF PA receives and amplifies an RF input signal to provide an RF transmit signal using an envelope power supply voltage. The envelope tracking power supply provides the envelope power supply voltage based on a setpoint, which has been constrained so as to limit a noise conversion gain (NCG) of the RF PA to not exceed a target NCG.
