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.

Claim (Index 19):
A method of providing amplification, the method comprising:\n providing a hybrid power amplifier module having a preliminary stage amplification device that includes a first transistor that is a silicon-based transistor device, a final stage amplification device that includes a second transistor that is a III-V transistor device made from a semiconductor material selected from gallium nitride, gallium arsenide, gallium phosphide, indium phosphide, and indium antimonide, intermediate circuitry coupling the preliminary stage amplification device and the final stage amplification device, wherein the intermediate circuitry includes a low-pass circuit and a high-pass circuit, and input pre-matching circuitry coupling the intermediate circuitry and the final stage amplification device; receiving a RF input signal at the preliminary stage amplification device; amplifying the RF signal by way of the preliminary stage amplification device to generate an amplified RF signal having a first component at a fundamental frequency and a second component at a harmonic frequency that is a multiple of the fundamental frequency; modifying the amplified RF signal by way of the intermediate circuitry so as to provide a modified amplified RF signal to the input pre-matching circuitry, wherein modifying the amplified RF signal includes harmonically terminating the second component at the harmonic frequency without implementing an impedance transformation of the first signal component at the fundamental frequency; further modifying the modified amplified RF signal by way of the input pre-matching circuitry so as to provide a further modified amplified RF signal to the final stage amplification device, wherein further modifying the modified amplified RF signal includes implementing the impedance transformation of the first signal component at the fundamental frequency; and further amplifying the further modified amplified RF signal so as to generate a RF output signal.
