Abstract

The switching arrangement is used for the redundant power supply for a power amplifier, especially a high-frequency power amplifier. The power amplifier in this context provides several output-stage components and several power-supply units. The power-supply units are connected together at their load-end connections and supply the output-stage components jointly with energy. If a power-supply unit fails, at least two output-stage components are actively switched off, so that the power amplifier can continue to operate although with reduced output power.
