| Zusammenfassung: | There is provided a power amplifier arrangement for amplifying an input power signal to an output power signal. The power amplifier arrangement comprises a main amplifier having an input and an output. The power amplifier arrangement comprises at least one auxiliary amplifier, each having an input and an output. The power amplifier arrangement comprises a power divider having an input and outputs. The input of the power divider is configured to receive the input power signal. Each output of the power divider is connected to a respective input of the power amplifiers. The power amplifier arrangement comprises a Doherty combiner comprising at least one Ruthroff transformer and configured to combine all the outputs of the power amplifiers to, at an output of the Doherty combiner, produce the output power signal. |
