Abstract
An apparatus and method for shielding for surface-mount LTCC components and filters to increase the signal isolation from input signal port to output signal port, and to increase isolation from other electrical signals external to the component or filter. Some embodiments include an interposer two-sided and plated through printed circuit board to provide a constant impedance transition from a surface-mount device input and output ports to corresponding input and output connection points of a circuit on a printed circuit board onto which the device is mounted, including a ground plane transition.
