Abstract
A packaged RF amplifier device includes a transistor and an output circuit. The transistor includes a control terminal and first and second current carrying terminals. The output circuit is coupled between the first current carrying terminal and an output lead. The output circuit includes first and second inductive elements coupled in series. The first inductive element, which may be a first bondwire array or an integrated inductance, is coupled between the first current carrying terminal and a node. The second inductive element, which includes a second bondwire array, is coupled between the node and the output lead. The device also includes a shunt circuit with a shunt capacitor and a third bondwire array coupled between the first current carrying terminal and the shunt capacitor. The first and second inductive elements and the third bondwire array are configured to have a desired mutual inductance.
