Abstract
This paper describes the various methodologies for realization of microwave subsystems through packaging of multiple bare MMICs. The use of LTCC substrate for packaging of hermetic multi-chip modules (MCM) has given significant benefits in terms of miniaturization and mass reduction. However, it poses several challenges for assembly and hermetic sealing of these large-size (>35 mm in both dimensions) LTCC modules. Various techniques for assembly and hermetic sealing were attempted and their outcomes are summarized.
