STRIPLINE LOAD Russian patent published in 2007 - IPC H01P1/26 

FIELD: radio (including microwave) engineering, radars, and measurement technology.

SUBSTANCE: proposed stripline load has board in the form of insulating plate incorporating electricity-conductive screen, input electricity-conductive stripline, and shorting device. Resistive absorbing layer having parallel-connected electricity-conductive components is electrically connected between input stripline and shorting device. Disposed above board in the form of plate in a spaced relation to each other are N additional insulating plates, where N is natural numerical series, their coefficient of heat conductivity being higher than that of plate material. N - 1 additional resistive absorbing layers with their additional parallel-connected electricity-conductive components electrically connected between input stripline and shorting device are disposed between N additional plates. Components disposed in clearances are interruptive structures abutting against lateral edges of absorbing layers. These components are made of electricity-conductive material whose melting point is lower than that of resistive material and of stripline and shorting-device electricity-conductive material. Sections of absorbing layers non-abutting against lateral edges of absorbing layers and plate surface sections contacting them have rough surfaces. Electricity-conductive screen and board can be provided with hole under absorbing layer incorporating electricity-conductive adjusting insert whose phase transformation occurs at temperature lower than melting point of resistive material and of stripline and shorting-device electricity-conductive material. Width of plate clearances may be reducing in direction from input stripline to shorting device. Width of clearances between all plates and thickness of all plates may be increasing in direction from board to N^th plate, and plate width may be reducing in direction from board to N^th plate. Components can be made as interruptive structures in the form of stubs abutting against lateral edges of absorbing layers, their interruption intervals may be increasing in direction from input stripline to shorting device. Absorbing layers can be different in width and not necessarily disposed one on top of other.

EFFECT: enhanced power dissipation, facilitated maintenance, enhanced safety of device and ability of coordinating its matching.
