More Information
Summary:An integrated radar circuit comprising: a first substrate, of a first semiconductor material, said first substrate comprising an integrated transmit and receive radar circuit; a second substrate, of a second semiconductor material, said second substrate comprising at least one through-substrate cavity having cavity walls; at least one discrete transistor chip, of a third semiconductor material, said at least one discrete transistor chip having chip walls and being held in said at least one through-substrate cavity by a metal filling extending from at least one cavity wall to at least one chip wall; a conductor on said second substrate, electrically connecting a portion of said integrated transmit and receive radar circuit to a discrete transistor on said at least one discrete transistor chip.
