Abstract
An amplifier includes a package that includes a carrier amplifier having a carrier amplifier input and output, a peaking amplifier having a peaking amplifier input and output, and corresponding input and output leads. The package includes a first integrated passive device including a first capacitor structure. The first integrated passive device includes a first contact pad coupled to the peaking amplifier output and a second contact pad coupled to the peaking output lead. The package includes a second integrated passive device including a second capacitor structure. The second integrated passive device includes a third contact pad coupled to the carrier amplifier output and a fourth contact pad coupled to the carrier output lead. The amplifier includes input circuitry a combining node configured to combine a carrier output signal and a peaking output signal.
