RESONANCE ELIMINATION IN HIGH SPEED PACKAGES

摘要

An optical microwave package eliminates launching electrical modes into a microwave strip-line by forming a moat in a housing portion of the package t o suppress microwave resonant energy. The moat can be filled with a conductive material to further suppress package resonances. Additionally, the bottom of a substrate positioned within the housing is isolated from any conductive metal to further suppress microwave resonant energy.
