The evolution of packages for monolithic microwave and millimeter-wave circuits

摘要

The maturing of monolithic microwave integrated circuit (MMIC) technology has spawned a variety of new military and commercial applications. As-a result, there is an increased emphasis on the packaging of MMIC chips and MMIC-based components. Currently, the industry is applying a number of new assembly and packaging technologies to RF components and subsystems driven by the forces of performance, size and weight, and cost. This paper outlines the current evolution in microwave and millimeter-wave packaging using examples drawn from the area of active array antennas.
