Claim of US Patent No. 11,071,239


1. A filter assembly comprising:a monolithic filter having a generally planar surface;
a heat sink directly attached to the generally planar surface of the monolithic filter, the heat sink comprising a layer of thermally conductive material that has a thickness that is greater than about 0.02 mm; and
an additional monolithic filter directly attached to the layer of thermally conductive material of the heat sink in a stacked arrangement such that the monolithic filter is directly attached to a first surface of the layer of thermally conductive material, and the additional monolithic filter is directly attached to a second surface of the layer of thermally conductive material that is opposite the first surface of the heat sink;
at least one via extending from the additional monolithic filter through the heat sink to the monolithic filter.
