Low Temperature Co-Fired Ceramic System on Package for Millimeter Wave Optical Receiver and Method of Fabrication

摘要

The present disclosure relates to a multi-layered low temperature co-fired ceramic (LTCC) system on package (SoP) for a millimeter wave optical receiver comprising a top layer, a plurality of first intermediate layers, a plurality of second intermediate layers, and a bottom layer. The top layer further comprises a matching network, passive components, and a signal line disposed on a substrate material, the plurality of first intermediate layers further comprises active amplification components, via holes and a plurality of inner grounding planes that are respectively disposed on a first plurality of LTCC substrates, the plurality of second intermediate layers further comprises a plurality of grounding planes that are respectively disposed on a second plurality of LTCC substrates; and the bottom layer further comprises a grounding plane that is disposed on the bottom surface of the second plurality of LTCC substrates. A method of fabricating the multi-layered LTCC SoP is also described.
