Patent ID: 7221244

Claim:
An RF shielding device for improving the Q-factor of a resonator component, comprising: a multilayer substrate including a first portion and a second portion; at least one surface mounted component positioned on the first portion; an RF component at least partially embedded in said first portion of said substrate and having a first Q-factor; a shield component disposed directly on and extending above the second portion, wherein the height of said shield component does not substantially extend effectively beyond the height of a tallest surface mounted component disposed on said first portion; said second portion of the substrate comprising a bottom surface and sidewall vias; and said shield suitably adapted to engage with said vias of said multilayer substrate in order to effectively define a substantially enclosed RF volume including the second portion and an area defined by the shield component adjacent the second portion; and a resonator component at least partially embedded in the second portion and having a second Q-factor partially determined by the enclosed RF volume.
