Additive Manufacturing of Frequency-Agile W-Band Packaging OSTI.GOV Craton, Michael Thomas; Papapolymerou, John; Chahal, Premjeet; Albrecht, John 2021-06-01 Keywords: Additive manufacturing, aerosol jet printing, heterogeneous integration, mm-wave packaging, nanocomposites, packaging, system-in-package, system-on-package. Abstract —In this paper we demonstrate a fully additively manufactured packaged W-band amplifier with integrated bypass capacitors. This package was fabricated using a chip-first approach and aerosol jet printing. Package substrates (dielectrics), conductors and interconnects are printed around a bare die attached to a carrier. This package uses Read More...
