Design of a triple-band power amplifier using a genetic algorithm and the continuous mode method

摘要

Dual band power amplifiers use either large and lossy matching networks, or switches, which do not allow concurrent operation. In this work, a concurrent, triple-band power amplifier with a simple matching network is presented. The theory of continuous modes of operation has been used in the optimization of the input and output matching networks using a genetic algorithm. As proof of concept, a design at 0.8, 1.8, and 2.4 GHz has been fabricated and characterized in the laboratory. A maximum power added efficiency and output power of 70% and 41 dBm have been achieved using our novel design. The design described in this paper is based on a solid theoretical analysis demonstrates a simplified biasing network. Such design is highly suitable for next generation wireless systems with aggregated carriers.
