Abstract
This invention relates to assemblies and processes for increasing the bandwidth of differential passive elements. The use of a floating plane in differential transmission lines is disclosed. One such assembly is a broadband balun having high even mode effective impedance, thus degrading the even-mode propagation or matching, and maintaining the desired odd mode effective impedance. Other assemblies can include line couplers, hybrid couplers, RF chokes with back-to-back baluns, and other elements, such as balanced filters.
