Abstract
An electronic device package includes a multilayer substrate having an interconnect structure configured to propagate a high frequency signal from one metal layer to another metal layer. The configuration and layout of the interconnect structure, particularly the arrangement of the reference vias associated with the signal via, is selected such that a desired filter response is achieved. The filter response is realized without any additional capacitor or inductor components. Thus, the natural discontinuity created by the vias and the inherent parasitic capacitance and inductance associated with the vias can be utilized to create a desired lowpass or bandpass filter response.
