Abstract
A multilayer ceramic package (200) with a floating element (202) to couple transmission lines (214) is disclosed. The package (200) has numerous dielectric layers (204A-204I) including an input electrode (206), an output electrode (208), a top ground plane (210) and a bottom ground plane (212). Transmission lines (214) are formed on some of the dielectric layers (204A-204I). Floating element (202) adjusts the electrical coupling between the transmission lines (214) and is spatially separated therefrom. This may provide the advantage of increased capacitive coupling between transmission line resonator structures in a multilayer packages, including non-adjacent resonant structures, without increasing the overall dimensions of the package (200). The floating element (202) may also increase the operable passband of a multilayer bandpass filter or provide a low-side transmission zero.
