Three dimensional package for monolithic microwave/millimeterwave integrated circuits

摘要

A three-dimensional interconnect package is provided for monolithic microwave/millimeterwave integrated circuits. A mating substrate for receiving an MMIC has transmission lines disposed over its surfaces. The mating substrate mounted substantially vertical in a base substrate which also has transmission lines for carrying microwave/millimeterwave signals. The transmission lines on both substrates are put in electrical contact and microwave/millimeterwave signals are transmitted between the substrates with a minimum of signal loss or reflection.
