Abstract:
An amplifier circuit includes an input port, an output port, and a reference potential port, an RF amplifier device having an input terminal electrically coupled to the input port, an output terminal electrically coupled to the output port, and a reference potential terminal electrically coupled to the reference potential port. An impedance matching network is electrically connected to the output terminal, the reference potential port, and the output port. The impedance matching network includes a reactive efficiency optimization circuit that forms a parallel resonant circuit with a characteristic output impedance of the peaking amplifier at a center frequency of the fundamental frequency range. The impedance matching network includes a reactive frequency selective circuit that negates a phase shift of the RF signal in phase at the center frequency and exhibits a linear transfer characteristic in a baseband frequency range.

Claim (Index 11):
A Doherty Amplifier circuit, comprising:\n a main amplifier that is configured to amplify an RF signal as between a main input terminal and a main output terminal across a fundamental frequency range; a peaking amplifier that is configured to amplify the RF signal as between a peaking input terminal and a peaking output terminal across the fundamental frequency range; an impedance transformer connected between the main output terminal and a combiner node; and an impedance matching network connected between the peaking output terminal and the combiner node; wherein the impedance matching network comprises a reactive efficiency optimization circuit and a reactive frequency selective circuit, wherein the reactive efficiency optimization circuit comprises reactive components that form a parallel resonant circuit with a characteristic output impedance of the peaking amplifier at a center frequency of the fundamental frequency range, and wherein the reactive frequency selective circuit is configured so that the RF signal at an intrinsic node of the peaking amplifier is substantially in phase with the RF signal at the combiner node at the center frequency and so that a transfer characteristic of the impedance matching network is substantially linear in a baseband frequency region that is below the fundamental frequency range.
