Discrete attenuator with parallel connection of cells — the way for dynamic range expansion without deterioration of radar-tracking receiver sensitivity

Symmetric and asymmetrical schemes of an attenuator with the parallel connection of cells which allows increasing a dynamic range of the receiver without deterioration of its sensitivity are developed and their rough parameters are given. The analysis of modern microwave components shows possibility of creation (in the simplest case) of an asymmetrical attenuator with the parallel connection of cells with depth of attenuation about 60-70 dB, insertion loss 1.5 dB, a maximum level of RF signal of 2 W, in a range of frequencies DC-26.5 GHz.
