Zusammenfassung:	A power amplifier. The power amplifier includes a plurality of parallel coupled transistors. Each transistor has a control terminal coupled to receive a signal to be amplified and an output terminal coupled to a node. The power amplifier also includes a matching network having an input coupled to the node and an output coupleable to a load. The power amplifier further includes a first circuit branch forming a choke and harmonic trap of the power amplifier. The first circuit branch includes a first inductance, a second inductance and a first capacitor. The first inductance has a first terminal coupled to the node and a second terminal coupled to a first terminal of the second inductance. A second terminal of the second inductance is coupled to AC ground. The first capacitor is coupled in parallel with the second inductance.
