The Wideband Marchand Balun Transition Design

RF_CE

This paper presents a practical and simple broadside coupled-line balun with multi-layers
profile microstrip line and broadside coupling structure to enhance the coupled coefficient and
balanced output bandwidth. Designed broadside coupled-line balun design with a symmetric
quarter wavelength coupled-line is developed to increase wider bandwidth efficiency and the
return loss is better than the traditional planar marchancd coupled-lines balun. The structure of
the designed balun is fairly simple, practical and easily fabricated. The measured results show
good agreements with those analyses data.
