FIELD: radio engineering.
SUBSTANCE: radioelectronic unit contains the housing in which by means of spacing sleeves and braces there fixed is pack of parallel installed printed circuit boards with radio elements installed on them, damping elements made in the form of plates from elastic high-porous material and installed between every neighbouring printed circuit boards of the pack and each of its extreme board and housing. Damping elements are formed with filling of boards on both sides with damping compound; braces are made in the form of adhesive interlayers arranged between damping elements of each neighbouring boards, as well as between housing and each extreme damping element.
EFFECT: improving reliability of the device at vibration and impact actions and providing the possibility of arranging large-size radio elements on boards.
