Abstract

A Doherty power amplifier includes a combining node that combines amplified output signals from first and second amplifiers. A reconfigurable impedance inverter circuit is coupled between the first amplifier and the combining node. The impedance inverter circuit includes an inductive element coupled between a first node and a second node, and a switching circuit coupled between the first node and the second node. A fundamental frequency tuning circuit and a harmonic frequency resonance circuit are coupled between the switching circuit and a ground reference node. When the switching circuit is configured in a first state, the fundamental frequency tuning circuit and the harmonic frequency resonance circuit are electrically coupled through the switching circuit to the first and second nodes. When the switching circuit is configured in a second state, the fundamental frequency tuning circuit and the harmonic frequency resonance circuit are electrically disconnected from the first and second nodes.
