Claim:
1. A semiconductor device comprising: a substrate having a surface; a first circuit on the substrate and comprising a plurality of electrical components; a second circuit on the substrate and comprising another plurality of electrical components; a housing coupled to the substrate, wherein the housing includes a major surface above the surface of the substrate, and an edge surface orthogonal to the major surface and the surface of the substrate, and wherein the housing encloses the first and second circuits; first and second connectors that project outward from the edge surface of the housing, wherein the first connector is coupled to the first circuit, the second connector is coupled to the second circuit, and the first and second connectors are physically separated from each other by a first distance across a portion of the edge surface; a ground connector that projects outward from the edge surface of the housing between the first and second connectors; and an isolation structure having an elongated first cross member coupled to the housing, and spaced from and extending over the surface of the substrate between the first circuit and the second circuit, wherein a length of the first cross member is greater than a width of the first cross member, and an area of the first cross member is smaller than an area of the surface of the substrate, and wherein the isolation structure further includes a first leg coupled to the housing and extending transverse to the first cross member and to the surface of the substrate, wherein the first leg is directly connected to the ground connector, the first leg has a width dimension that is parallel to and smaller than the first distance between the first and second connectors, and wherein the isolation structure is configured to reduce electromagnetic coupling between the first circuit and the second circuit during an operation of at least one of the first circuit and the second circuit.
