Zusammenfassung:Embodiments of a device and method are disclosed. In an embodiment, a Doherty amplifier module includes a first amplifier die with a first output terminal, a second amplifier die with a second output terminal, and a wideband impedance inverter circuit electrically coupled between the first and second output terminals. The wideband impedance inverter circuit includes a network of capacitors, the network of capacitors including at least a series capacitor having a positive capacitance, a first shunt circuit having a first negative capacitance, and a second shunt circuit having a second negative capacitance.
