Microwave and millimeter wave device mounted on a semiconductive substrate and comprised of different kinds of functional blocks

摘要

A microwave and millimeter wave device includes: a dielectric substrate including at least one signal line, a passive circuit and a first grounding conductor portion which are formed on a surface side of the dielectric substrate; and a semiconductor substrate including a plurality of active elements. The signal line is physically and electrically connected to an input/output terminal of the active element via a metal bump; and the first grounding conductor portion is physically and electrically connected to a grounding terminal of the active element via another metal bump.
