Wireless communication node with multi-band filters

A wireless communication network node comprising:

• at least one antenna arrangement,
• at least one radio arrangement,
• at least one power splitter arrangement, and
• at least one power amplifier,
• where each antenna arrangement in turn comprises at least one antenna device, and where each power splitter arrangement comprises an input port and at least two output ports, wherein each of said at least one power amplifier is connected to a corresponding input port, and where, for each power splitter arrangement, the at least two output ports of each power splitter arrangement are connected to at least one corresponding antenna device via a corresponding multi-band filter for each of the at least two output ports of the each power splitter arrangement, where each multi-band filter is arranged for at least two frequency bands, and
• wherein the wireless communication network node comprises a first power amplifier, a second power amplifier, a first power splitter arrangement, a second power splitter arrangement, where the first power amplifier is connected to an input port of the first power splitter arrangement and where the output ports of the first power splitter arrangement are connected to a first set of antenna devices of a combined antenna arrangement via corresponding multi-band filters for each of said output ports and phase shifters, and where the second power amplifier is connected to an input port of the second power splitter arrangement, where the output ports of the second power splitter arrangement are connected to a second set of antenna devices of the combined antenna arrangement via corresponding multi-band filters for each of said output ports and phase shifters, the combined antenna arrangement comprising antenna devices of a first polarization and a second polarization, where first polarization is orthogonal to the second polarization.
