Envelope Tracking

  

Envelope Tracking Applications

Envelope Tracking is a power supply technique for improving the energy efficiency of Radio Frequency Power Amplifiers by tracking the power demand as opposed to today’s fixed power systems.

With switching transition speeds in the sub nano-second range, Gallium nitride power transistors are being seen as an enabling technology for both ET converters and wide bandwidth RF Power Amplifier designs. The ultra fast switching capabilities of eGaN® FETs enable the high frequency multi-phase buck converters used in Envelope Tracking.
