Abstract

With the recent popularization of nanosatellite technologies, the industry is putting a notable effort into increasing the performance of the systems integrated in these small spacecrafts. In this paper, a novel outphasing amplification architecture to enhance the power efficiency of a satellite downlink is presented and evaluated. Based on a conventional LINC (LInear amplification with Nonlinear Components) architecture, the proposed architecture transmits both outphased signals, and carry out the signal combination in the receiver in the base-band domain. The resulted architecture takes advantage of an efficient signal amplification given by the nonlinear power amplifiers, while the elimination of the signal power combiner from the transmitter, increases the overall power efficiency. We outline and analyze those elements that restrict the performance of this novel approach. The simulations and laboratory experimentation probes the proposed architecture is feasible, and able to improve a ?? % the power efficiency, compared to a classic transmitter front-end architecture.
