An Electromagnetically Coupled Package Feed-Through Structure for Multilayer Carrier Substrates

Theoretical and first scaled experimental results are presented for an electromagnetically coupled feed-through structure for multilayer carrier substrates. This structure combines an inherent DC isolation with an improved hermetic sealing, as no conductor - at least for the RF - needs to penetrate the top layer of the substrate. The design of this interconnect is done using a FDTD software.
