Abstract
A differential Doherty amplifier circuit includes a first differential amplifier including a first carrier amplifier and a second carrier amplifier, a second differential amplifier including a first peak amplifier and a second peak amplifier, a first line connected to the first carrier amplifier and the first peak amplifier, and a second line connected to the second carrier amplifier and the second peak amplifier. The first differential amplifier and the second differential amplifier are formed on a die of a chip device parallel to an XY plane. The first line and the second line are each formed of a wiring line disposed in a substrate parallel to the XY plane. The chip device is flip-chip mounted on the substrate in a Z direction orthogonal to the XY plane.
