Three-dimensional MMIC technology for low-cost millimeter-wave MMICs

This paper highlights the key advantages of the three-dimensional (3D) MMIC technology in the millimeter-wave frequency band and demonstrates recently developed compact 3DMMICs. This paper also proposes a new methodology for MMIC development based on 3D/multilayer MMIC technology that greatly reduces the costs of millimeter-wave MMICs. The new technology achieves compact and highly integrated millimeter-wave MMICs that are extremely cost effective.
