Similar to analog envelope tracking amplifiers, the supply modulator efficiency is crucial to the overall power efficiency of the amplifier. Results for a GaN switch-mode power amplifier with a supply modulator are shown. A second method of enhancing power efficiency using out-of-band energy recovery is also discussed.

In this talk, we discuss switch-mode power amplifier architectures which employ supply modulation techniques to reduce out-of-band noise
