            Abstract : 
The paper concerns the application of the electrochemical alumina technology for the formation of chips with passive part for microwave attenuators. The structure of this chip consists of an aluminum base with an anodic dielectric Al2O3 layer, copper strip lines and contact pads at the alumina surface, and a thin-film resistor. Experimental results verify availability of this technology for the microwave attenuator manufacturing.
