Automated power amplifier design assisted with particle swarm optimization

This paper presents a method that realizes automated power amplifier design (APAD). The APAD contains two aspects: the load-pull simulation, which determines the order of the harmonic waves controlled according to efficiency, gain and output power requirement, and the automated impedance matching, which is based on the particle swarm optimization (PSO). As an example, the GaN HEMT Power amplifier (PA), the fundamental and second harmonic waves controlled and the T-type matching network synthesized by the PSO algorithm, is simulated in Advance System Design (ADS) and the maximum power added efficiency (PAE) is up to 80% at 2.14GHz, which is as good as other prevalent PA topologies, such as Class E, Class F and Class J.
