Beyond Envelope Tracking

Higher energy efficiency

  • Highly relevant for battery powered devices

  • Usage of special kind of power amplifiers that can be operated at saturation level and no real-time feedback receiver overhead

No bandwidth limitation

  • High instantaneous bandwidth meets requirements for current and future mobile communication standards

  • Open loop forward architecture is used without digital predistortion

Low spectral noise

  • Helps with specification compliance

  • New implementation exhibits much less noise compared to other outphasing systems

Future proof

  • Potentially a platform technology compatible with a wide range of high frequency signal types

  • Modulation scheme and the way how the front-end is working does not have any limitation
