Abstract:
A Marchand balun has a primary transmission line with a width smaller than the two secondary transmission lines. The two secondary transmission lines also have different widths and lengths. This arrangement provides an imbalance between the widths and lengths of the transmission lines. It has been found that this imbalance can enable improved amplitude unbalance and phase unbalance.
