Gestapeltes HF-Modul

摘要

A stacked radio-frequency module is formed by stacking packages each storing MMICs and mounting another package upside down which stores a control circuit for controlling MMICs. The MMICs and control circuits are each sealed by a metal sealing lid within the cavity of each of the packages which are spatially completely separated from each other. Each of the pads for wiring paths for radio-frequency signals and for power supply/control signals and ground pads are provided within each package and at opposing surfaces of packages to be stacked with corresponding pads joined by a gold bump.
