Improving efficiency at back-off power levels has become an active area of research to support spectrally efficient modulation schemes with high peak-to-average power ratios. Doherty power-amplifier topology and envelope-tracking supply modulation are key enablers to improve the back-off efficiency of transmitters. Increasing signal bandwidths for applications such as carrier-aggregation LTE and WiFi 802.11ac poses challenges for supply modulation. Implementing the Doherty topology for 5G applications operating at mm-wave frequencies is an active area of research.
