Abstract

This paper proposes a new power amplifier's linearization architecture for a unified access point uses a wideband power amplifier and transmits multi-band signals concurrently for system's flexibility. To achieve high power efficiency and low interference of the access point, we evaluate a concurrent dual-band digital predistortion (DPD) technique for the wideband amplifier using a feedback loop. A concurrent dual-band mixer is applied in the feedback loop to reduce the complexity and the cost. In addition, DPD is operated at low IF to reduce nonsymmetrical spectral regrowth. The simulation result shows the validity of this architecture and a good linearization performance.
