    摘要： A power amplifier configured to receive an AC input signal and output, based on the AC input signal, an output voltage via a first output voltage terminal and a second output voltage terminal. The power amplifier includes a first transistor and a second transistor connected in a push-pull configuration, a first inductor, a second inductor, and a first capacitor. The first output voltage terminal is located between the first inductor and the first transistor. The second output voltage terminal is located between the second transistor and ground. The first capacitor is configured to provide a first circuit path between the first output voltage terminal and the second output voltage terminal. The first circuit path functions as a short circuit for even harmonics of a fundamental frequency of the AC input signal but does not function as a short circuit for the fundamental frequency of the AC input signal.

    摘要： A radio frequency power amplifier module for a dual-band type mobile communication apparatus that can transmit and receive a first frequency f1 and second frequency f2 (f2=2×f1). It includes a drive stage amplifier having the gain peaks at f1 and f2 with a matching circuit and a radio frequency power output circuit including a radio frequency power output transistor. The output circuit has a transmission line connected to the drain end of the output transistor, a parallel resonance circuit connected in series to the transmission line to resonate at harmonics of a frequency twice the frequency f2, a series resonance circuit provided between one end of the resonance circuit and the ground to resonate at harmonics of a frequency twice the frequency f2 and an output matching circuit provided in series to the other end of the parallel resonance circuit for matching with f1 and f2.
