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.
