Abstract
Embodiments of a method and device are disclosed. In an embodiment, a Doherty amplifier module includes a substrate including a mounting surface, and a carrier amplifier die, a first peaking amplifier die, and a second peaking amplifier die on the mounting surface. The carrier amplifier die includes a first output bond pad that has a first length and a first width. The first peaking amplifier die includes a second output bond pad including a first main pad portion having a second length and a second width and including a first side pad portion having a third length and a third width. At least one of the second width or the third width is greater than the first width. The second peaking amplifier includes a third output bond pad. A first wirebond array is coupled between the third output bond pad and at least the first side pad portion.
