Abstract
Hybrid power amplifier circuits, modules, or systems, and methods of operating same, are disclosed herein. In one example embodiment, a hybrid power amplifier circuit includes a preliminary stage amplification device, a final stage amplification device, and intermediate circuitry at least indirectly coupling the preliminary stage amplification device and the final stage amplification device. The intermediate circuitry includes a low-pass circuit and a high-pass circuit, and the hybrid power amplifier circuit is configured to amplify a first signal component at a fundamental frequency. Due at least in part to the intermediate circuitry, a phase of a second signal component at a harmonic frequency that is a multiple of the fundamental frequency is shifted.
