Abstract
A power amplifier (PA) envelope power supply, radio frequency (RF) PA circuitry, and a process to select a converter operating mode of the PA envelope power supply based on linearity requirements of the RF PA circuitry is disclosed. The PA envelope power supply operates in one of a first converter operating mode and a second converter operating mode. The process for selecting the converter operating mode is based on a required degree of linearity of the RF PA circuitry. The PA envelope power supply provides an envelope power supply signal to the RF PA circuitry. Selection of the converter operating mode may provide efficient operation of the PA envelope power supply and the envelope power supply signal needed for proper operation of the RF PA circuitry.
