POWER ATTENUATOR Russian patent published in 2014 - IPC H03H7/24 

FIELD: radio engineering, communication.

SUBSTANCE: power attenuator comprises N series-connected matched links on identical substrates mounted with equal spacing on a heat-conducting base; each subsequent link, for the same power losses therein, has higher attenuation than the previous link and the power transfer coefficient of the links (K_P<1) is a function of at least two parameters, e.g. K_PM=f(N, M,…), where N is the number of links; M is the index number of a link (M=1, 2, 3,…, N). The attenuator has a terminal connected to the output of the corresponding link, which corresponds to the parameters: number of links to said terminal and power transfer coefficient from the input to said terminal.

EFFECT: broader functional capabilities and high reliability.
