Abstract: A directional coupler is described comprising two housing parts which define at least two hollow conductors and a separation wall positioned between both hollow conductors. Said separation wall comprises several holes ensuring a coupling of the at least two hollow conductors. Said several holes are arranged in two rows in an alternating manner such that a galvanic connection of both housing parts is provided between each neighbored holes. Further, a combiner is described.

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.

Abstract: A high-load coupler with a first input port, which is connected via a first stripline to an output port, and with at least one second input port, which is connected to an absorber, which provides at least one second stripline, a coupling portion and a connection portion. The at least one second input port is connected via at least one second stripline directly to the absorber. The at least one second stripline is designed as a middle conductor of a triplate line and the absorber is disposed on a thermally-conductive surface of a cooling-medium pipe. The cooling-medium pipe is connected to one housing half.
