Abstract
A power amplifier including: a main power amplification device having an output; an auxiliary power amplification device having an output; a load modulation circuit operably connected to the output of the main power amplification device and the output of the auxiliary power amplification device; and a post-matching circuit operably connected to load modulation circuit. The load modulation circuit is arranged to enable fundamental frequency load modulation and to enable modulated harmonic terminations of at least the second and third harmonic frequencies. The modulated harmonic terminations may include drain terminations.
