Abstract
Apparatus and methods for power amplifier output matching is provided. In certain configurations, an output matching circuit includes a supply voltage biasing circuit electrically connected between an input node and a power high supply voltage, a second-order harmonic series resonant circuit electrically connected between the input node and a power low supply voltage, a third-order harmonic parallel resonant circuit electrically connected between the input node and a harmonic frequency grounding node, a third-order harmonic series resonant circuit electrically connected between the harmonic frequency grounding node and the power low supply voltage, and a DC blocking capacitor electrically connected between the harmonic frequency grounding node and an output node.
