Abstract
A multilayer balun includes first, second, and third terminals, first and second inductors, and an open line conductor. The first inductor is electrically connected between the first terminal and ground points. The second inductor is electrically connected between the second terminal and the third terminal and is magnetically coupled with the first inductor. The open line conductor has one end that is an open end and another end that is electrically connected to a via conductor pattern, which is a signal path between the first terminal and ground points.
