Abstract
A radio frequency (RF) module comprises a conductive top layer configured to improve RF interference-shielding functionality with respect to one or more RF devices disposed on the module. The conductive top layer may be segmented as to form one or more segments of the top layer that are at least partially electrically isolated from surrounding segments or devices. A module may have a plurality of devices disposed thereon, wherein separate, at least partially isolated, top conductive layers correspond to different devices of the module. The top layer may be etched or cut to achieve such segmentation.
