Abstract
In this paper we propose to combine the concepts of outphasing and analog-radio over fiber. The analog outphasing signals are generated centrally and transported to the remote antenna system over fiber. There, high-performance and highly non-linear power amplifiers can be used. This approach creates an energy efficient communications infrastructure based on a centralized radio network. A first demonstrator is built at Ka-band using discrete components, experimentally showing the feasibly of this concept at millimeter-wave. Preliminary results show a measured error-vector magnitude of 4.18% over a wireless channel.
