It is known to use power combiners comprising electrical conductors to bring together multiple high-frequency signal sources and/or to split a high-frequency signal. A power combiner that includes a second electrical conductor that is spaced apart from a first electrical conductor is known from EP 1 699 107 A1, in which the first electrical conductor is capacitively and inductively coupled to the second electrical conductor. Both the first electrical conductor and the second electrical conductor can include multiple windings to increase the inductive coupling between the conductors, in accordance with EP 1 699 107 A1.
Other power combiners are known, for example, from U.S. Pat. No. 8,044,749 B1, DE 103 42 611 A1, and US 2014/0085019 A1.
