摘要：
A power management system for a radio frequency (RF) power amplifier (PA) load is disclosed. The power management system includes a first switching power supply that is adapted to output a relatively constant voltage, an electronic switch for selectively coupling the first switching power supply to the RF PA load, and a second switching power that is adapted to output a dynamic DC voltage to the RF PA load. The power management system further includes a control system that is adapted to close the electronic switch to supply the relatively constant DC voltage in addition to the dynamic DC voltage to the RF PA load in a first mode and to open the electronic switch wherein the relatively constant DC voltage is not supplied to the RF PA load in a second mode.
