An apparatus and method for hermetically sealing, EMI shielding integrated circuits for high-speed electronic devices using a combination of microstrip to buried stripline interface for signal transmission from the integrated circuit. The packaging provided comprises a first plurality of microstrips interconnecting the integrated circuit to a plurality of buried striplines exposed on a surface of the main substrate. A ceramic interposer placed over the main substrate “buries” a portion of the exposed striplines on the main substrate to thereby insulate these signal paths from a hermetically sealing, and EMI shielding metal lid placed over the integrated circuit. The metal lid and the seal ring brazed over the ceramic interposer thus provide both a hermetic seal and an electric radiation block. A reduction in dispersion due to the buried striplines is also achieved, as well as improving jitter performance.
