Abstract
This disclosure relates to a harmonic termination circuit that is separate from a load line. In one embodiment, the load line is configured to match an impedance at the power amplifier output at a fundamental frequency of the power amplifier output and the harmonic termination circuit is configured to terminate at a phase corresponding to a harmonic frequency of the power amplifier output. According to certain embodiments, the load line and the harmonic termination circuit can be electrically coupled to the power amplifier output external to a power amplifier die via different output pins of the power amplifier die.
