摘要：
A balun network is provided having first and second conductor portions symmetric along a center line therebetween. A connecting conductor portion 130 couples ends of the first and second conductor portions with a spacing therebetween. The first and second conductor portions have a like-length of one-quarter wavelength. A balanced port 140 is provided between a first end of the first conductor portion 110 and a first end of the second conductor portion 120. An unbalanced port 150 is provided between a ground reference plane 160 and a first end of the first conductor portion.
