STRIP ATTENUATOR Russian patent published in 2007 - IPC H01P1/22 

FIELD: radio engineering; microwave engineering; radars, radio communications, and measurement technology.

SUBSTANCE: proposed strip attenuator has board in the form of insulating plate with electricity-conductive screen, input and output electricity-conductive striplines, and resistive absorbing layer with parallel-connected electricity-conductive components. Absorbing layer is electrically connected between input and output striplines. Attenuator is provided with additional electricity-conductive screen. Disposed above board in the form of plate in a spaced relation to one another are N additional insulating plates, where N is natural series of numbers, whose coefficient of thermal conductivity is higher than that of board. N - 1 additional resistive absorbing layers are disposed between N additional plates with parallel-connected additional electricity-conductive components electrically connected between input and output striplines. All absorbing layers and relevant parallel-connected components are disposed in plate-to-plate clearances. Components are interrupted structures abutting against lateral edges of absorbing layers and made of electricity-conductive material whose melting point is lower than that of resistive material and stripline electricity-conductive material. Absorbing-layer sections which do not abut against lateral edges and contact these sections have rough surfaces. Electricity-conductive screen and board can be provided with holes under absorbing layer to receive electricity-conductive adjusting insert whose phase transform is started at temperature below melting point of resistive material and stripline electricity-conductive material. Plate-to-plate clearances may reduce in direction from input to output stripline. Clearances between all plates and thickness of all plates may increase in direction from board to N^th plate and width of plates may reduce in direction from board to N^th plate. Components can be made in the form of interrupted structures abutting against lateral edges of absorbing layers of stubs; interruption intervals may increase in direction from input to output stripline. Width of absorbing layers may be different and their lateral edges are not to be necessarily disposed one on top of other.

EFFECT: enhanced dissipation power and safety in device adjustment, facilitated maintenance, ability of regulating device matching.
