A low cost and high performance millimeter wave (MMW) radio frequency transceiver module includes a substrate board and plurality of microwave monolithic integrated circuit (MMIC) chips supported by the substrate board and arranged in a receiver section, a local oscillator section and a transmitter section. A plurality of filters and radio frequency circuit interconnects are formed on the substrate board and operative with and/or connecting the receiver, local oscillator and transmitter sections. A plurality of electrical interconnects are operative with and connect the receiver, local oscillator and transmitter sections. A method of forming the millimeter wave radio frequency transceiver module is also disclosed.

Millimeter wave (MMW) radio frequency transceiver module and method of forming same

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.
