Abstract
A balun includes a first transmission line and a number (N) of second transmission lines. The first transmission line includes an end terminal for receiving or outputting a signal with a target wavelength, and having a length of half the target wavelength. Each of the second transmission lines is disposed adjacent to and spaced apart from the first transmission line so as to establish electromagnetic coupling therebetween, and includes first and second end terminals for cooperatively outputting or receiving a differential signal pair with the target wavelength.
