Abstract
A microwave substrate is formed by thermocompression bonding a metalization system layer to two substrates having corresponding properties. One of the properties in one material is significantly different in value than that property in the other material. The substrates are selected from polycrystalline and monocrystalline ceramic materials. The bonded slabs are sliced and ground planes attached to form finished composite substrates.
