RADIO-ELECTRONIC UNIT Russian patent published in 2013 - IPC H05K7/20 

FIELD: radio engineering, communication.

SUBSTANCE: radio-electronic unit has a housing and functional cells having printed-circuit boards with radio elements and heatsinks. According to the invention, the housing is made of dielectric material in form of a continuous structure with inner partition walls which form compartments accommodating the functional cells, wherein the central compartment of the housing accommodates a transformer board, having four paired pulse transformers with symmetrical arrangement of windings; at opposite sides of the transformer board there are four functional cells at each side, each placed in a separate compartment of the housing and representing a transistor unit, having two printed-circuit boards connected by insulating bars with threaded openings for mounting into the housing, wherein the first printed-circuit board has three clamp diodes and the second printed-circuit board has a high-voltage power transistor. The second printed-circuit board is double-sided and has areas with the same shape as the transistor housing on two sides and has metal-coated openings which the heatsink function as heat-removing pipes.

EFFECT: high efficiency of cooling powerful radio elements and reliability, improved weight and size characteristics.
