摘要
A low cost millimeter wave (MMW) module for a microwave monolithic integrated circuit (MMIC) includes a carrier board formed of a dielectric material and having at least one MMIC die mounted thereon and at least one interface line, such as a 50 Ohm microstrip interface line. A base plate is formed of a material that has a higher unmatched coefficient of thermal expansion (CTE) than the carrier board and supports same. A housing is mounted over the carrier board and engages the base plate. The housing has at least one subminiature coaxial connector (SMA) interface mounted thereon. A flexible circuit interconnect, such as a fuzz button, connects the subminiature coaxial connector and MMIC die through the interface line. A thermal interface member is positioned between the carrier board and base plate to aid in heat transfer between the base plate and housing and the lower CTE carrier board.
