Abstract:
A Doherty amplifier is provided. The Doherty amplifier includes a first path circuit including a carrier amplifier and a first impedance adjusting circuit connected with the carrier amplifier; and a second path circuit including a peaking amplifier, a second impedance adjusting circuit connected with the peaking amplifier, and a peaking amplifier bias circuit connected with the peaking amplifier. At least one among an impedance of the first impedance adjusting circuit, an impedance of the second impedance adjusting circuit, and a bias of the peaking amplifier bias circuit is adjusted in response to a control signal.
