eGaN FETs for Envelope Tracking

Envelope tracking is a power supply technique for improving the energy efficiency of radio frequency power amplifiers by precisely tracking the power demand, as compared to today’s fixed-power systems. Envelope Tracking can double base station efficiency and increase cell phone talk time. In this video, we discuss the ultra-fast performance of our 60 W, 20 MHz bandwidth, 4-Phase, LTE compatible envelope tracking demonstration board using eGaN FETs.
