High Value Passive Component Integration in LTCC Technology

This paper presents the use of a unique component geometry to fabricate large valued inductors buried in an LTCC substrate. The large valued inductors presented create a self shielding buried component that require no external shields to isolate the inductor from other components in the circuit. As a demonstration of the usefulness of such a component, an example SAW filter matching circuit is discussed. The performance of the SAW filter and integrated matching circuit is also presented.
