Patent ID: 6873228

Claim:
An apparatus including self-resonant radio frequency (RF) circuitry within a multilayered low temperature co-fired ceramic (LTCC) substrate, comprising: a first ceramic tape layer with a plurality of interface electrodes; a second ceramic tape layer with a plurality of circuit electrodes for at least an RF integrated circuit; a plurality of intermediate ceramic tape layers positioned between said first and second ceramic tape layers with a plurality of electrode patterns; and a plurality of conductive paths, each of which includes one or more conductive vias and one or more portions of selected ones of said plurality of electrode patterns, mutually coupling selected ones of said pluralities of interface electrodes, circuit electrodes and electrode patterns; wherein one of said first, second and plurality of intermediate ceramic tape layers includes an electrode pattern with at least a portion coupled to at least one of said plurality of interface electrodes by a first one of said plurality of conductive paths, a dielectric paste deposited upon said electrode pattern portion, and a conductive plate disposed on at least a portion of said dielectric paste, thereby forming, together with said dielectric paste and electrode pattern portion, a capacitance, said conductive plate is coupled to at least one of said plurality of circuit electrodes by a second one of said plurality of conductive paths, and said first and second conductive paths together form an inductance such that said inductance and said capacitance together form a series resonant impedance at a predetermined frequency of resonance.
