Abstract
A 3 dB coupler includes at least one first and one second electric conductor that are spaced apart from each other and are capacitively and inductively coupled to each other in a coupling region. The first conductor represents the primary side of a transformer, and the second conductor represents the secondary side of the transformer. The first and second conductors each have a winding number of n>1.
