ABSTRACT:
A power amplifier arrangement comprises a power amplifier in a semiconductor body. At least one first input terminal on the surface of the semiconductor body is provided for feeding in a signal to be amplified. A first output tap of the arrangement is designed for outputting a signal with a first center frequency; a second and a third output tap are designed for outputting a second signal with a second center frequency. A line wire is respectively connected to the second and third output taps on the surface of the semiconductor body. According to the invention, a charge store is provided, which is coupled to the third output tap and is designed for forming a series resonant circuit with the line wire connected to the third output tap.
