%X In this paper, comprehensive design considerations for multi-stage envelope tracking power amplifier line-up design with a 10W GaN HEMT switch mode driver amplifierwas presented to realized optimum overall power added efficiency.Crest factor reduction algorithm and non-linear switch mode driver design for efficiency and linearization were studied. Also, a high efficiency inverse class-F amplifier was implemented with efficiency as 44.8% for LTE 20MHz signaland characterized to provethe concept of applying linearizable inverse class-F amplifierenvelope tracking driver purpose.
