Integrated, Ultra-Efficient Envelope Modulator

MaXEA is a high-voltage, integrated envelope modulator for use in efficient envelope-tracking RFPAs.

Envelope Modulation

MaXEA supports advanced modulation standards with non-constant amplitudes:

  • high peak-to-average power ratios
  • wide modulation bandwidths
  • stringent linearity requirements
