Abstract
In a four-port transmission-line network, a first transmission line is connected to a first port, second and third transmission lines are connected to a first component port, fourth and fifth transmission lines are connected to a second component port, and a sixth transmission line is connected to a fourth port. The transmission lines are connected as baluns to the ports with the unbalanced signal on the port side and the balanced signals interconnecting with others of the transmission lines. In another example, two or more baluns are connected serially. Each balun includes two transmission lines having signal-return conductors connected together at the ends. One end of a signal conductor on the first balun forms a sum port. One end of the signal-return conductors of the second balun forms a difference port, and a capacitor connects the other end of the signal-return conductors to circuit ground.
