Abstract: A system configured to increase a reliability of electrical connections in a device. The system including a lead configured to electrically connect a pad of at least one support structure to a pad of at least one electrical component. The lead includes an upper portion that includes a lower surface arranged on a lower surface thereof. The lower surface of the upper portion is arranged vertically above a first upper surface of a first pad connection portion; and the lower surface of the upper portion is arranged vertically above a second upper surface of the second pad connection portion. A process configured to increase a reliability of electrical connections in a device is also disclosed.

Abstract: A transistor die includes a transistor including a control terminal, an output terminal, and a first partial matching circuit. The first partial matching circuit is connected to at least one of the control terminal of the transistor and the output terminal of the transistor, and is configured to tune an input impedance of the transistor die. A packaged device is also provided.
