Abstract

A power amplifier includes a substrate, first and second transistor amplifiers, and at least one matching circuit. Respective output terminals of the first and second transistor amplifiers are coupled to a combining node, and the matching circuit includes one or more passive electrical components coupled between one of the respective output terminals and the combining node. At least one of the first and second transistor amplifiers or the one or more passive electrical components is mounted on the substrate in a flip chip configuration. The matching circuit may include a shunt inductance that is coupled to the one of the respective drain terminals by a conductive bump. Related devices are also discussed.
