Abstract:
1. A packaged solid state assembly comprising: a) a first ceramic substrate and a second ceramic substrate and at least one solid state device located therebetween, each solid state device comprising a body having a coefficient of thermal expansion and a plurality of conductive contacts on a surface of the body facing the second ceramic substrate; b) the first ceramic substrate comprising: c) a second ceramic substrate comprising: d) a plurality of terminals connected to the conductive pads on the upper surface of the second ceramic substrate; e) a strip line comprising an insulating body, a first conductive strip and a second conductive strip, the first conductive strip being connected to a conductive pad on the first ceramic substrate or the second ceramic substrate, and the second conductive strip being connected to a different conductive pad on the first ceramic substrate or the second ceramic substrate; and f) a first encapsulant having a coefficient of thermal expansion matched to the coefficient of thermal expansion of at least one solid state device, encapsulating the solid state devices between the first ceramic substrate and the second ceramic substrate.
