EPC eGaN® FET Application:
RF Envelope Tracking

In this video EPC demonstrates what power and efficiency levels are readily realizable using eGaN FETs in a buck converter for high power envelope tracking applications. The need for improving the RF Power Amplifier (PA) system efficiency used in envelope tracking has become an intense topic of research and development due to the ever increasing need for improved cell phone battery life, better base station energy efficiency, and more output power from very costly RF transmitters.
