Devices (1) comprising elements (5) with electrodes coupled to connections (11,12), one or more connections (11,12) forming part of an impedance transforming network, get reduced electromagnetic couplings between the connections (11,12) by locating largest parts of the connections (11,12) in non-parallel planes. This also reduces unwanted feedback and deteriorations of transfer characteristics of the elements (5) and allows the electrodes of the elements (5) to be located closer to each other resulting in reduced sizes. The largest parts of the connections (11,12) do not form part of each other?s plane and do not form part of one and the same plane. The planes make an angle between 45 degrees and 135 degrees. One connection (11,12) has a shape such as a loop for further reducing the electromagnetic coupling. One or more of the connections (11,12) that form part of the impedance transforming network comprise an inductance and one or more of the connections (11,12) are coupled to element-external capacitors (13,14).
