Zusammenfassung:	A class-F power amplifier (PA) with a matching network is disclosed herein. The class-F PA comprises a first switch and a second switch operating in differential mode, with a second harmonic trap circuitry selectively terminating the drain terminals to ground at a second harmonic frequency. The second harmonic trap circuitry comprises a plurality of lumped inductive and capacitive components. The PA further comprises a common mode trap and a matching network to reduce the imbalance of the drain terminal impedance between first harmonics and third harmonics.
