Abstract
A packaged transistor amplifier includes a package having an input lead and an output lead; a transistor stage having a plurality of unit cell transistors that are electrically coupled to the input lead in parallel, each of the unit cell transistors having an output; a first output bond pad that is coupled to a first subset of the outputs of the unit cell transistors by a first feed network; a second output bond pad that is separate from the first output bond pad, the second output bond pad coupled to a second subset of the outputs of the unit cell transistors by a second feed network; a first output bond wire coupled between the first output bond pad and the output lead; and a second output bond wire coupled between the second output bond pad and the output lead. Related design methods are also provided.
