The present invention provides an amplifier circuit for amplifying an incoming signal, the amplifier circuit comprising at least two signal paths configured to amplify signals of different overlapping frequency bands, a signal splitter comprising an input port configured to receive the incoming signal, the signal splitter being coupled to an input side of the signal paths and configured to split the incoming signal into split signals for the signal paths, and a diplexer coupled to an output side of the signal paths and configured to combine the amplified signals and provide a combined amplified signal. Further, the present invention provides a respective method.

Amplifier circuit and method

A power directional coupler is described which comprises two hollow conductors and a separation wall. Said separation wall has a coupling portion which comprises several holes which are arranged in said separation wall such that a high hole-wall relation is obtained, ensuring a good coupling at a small size of said power directional coupler. Further, a combiner and a method for manufacturing said power directional coupler and a combiner are described.
