FIELD: physics; radio.
SUBSTANCE: present invention pertains to radio engineering and can be used for making radio-electronic units for increasing efficiency of protecting a radio-electronic unit from electromagnetic interference and reducing its weight and size. The outcome is achieved by that, the radio-electronic unit with on-board shielding has a multi-layered printed circuit board, bearing connection strips, connection pads and radio components, forming functional zones. At least one of these functional areas can be shielded. The ground potential supply conductor is in the inner conducting layer of the multi-layered printed circuit board, made in form of metallised plane, electrically connected to the point of input the ground potential to the multi-layered printed circuit board. The shielded functional area, in at least the outer conducting layer of the multi-layered printed circuit board, is surrounded by a shielding barrier on the perimeter, electrically connected by structural element of interlayer connections to an extra metallised plane. The structural element of the interlayer connections is in form of a metallised slot for interlayer connections, passing along the printed shielding barrier, forming a conductive pattern in the layer of the multi-layered printed circuit board, perpendicular the base plane of the dielectric of the multi-layered printed circuit board. The width of the conductive pattern is equal to the thickness of the printed circuit board. The metallised slot, passing along the printed shielding barrier, is filled with solder. The thickness of the conductive pattern, perpendicular the base plane of the dielectric, is equal to the width of the slot. Printed shielding barriers are located on the perimeter of a hexagon or square and/or rectangle or along a circle. Functional areas are in a honeycomb order. In the functional areas there are separate radio elements or a group of radio elements.
EFFECT: increased efficiency of protecting the radio-electronic unit from electromagnetic interference and reduction of its weight and size.
