UHF ATTENUATOR Russian patent published in 2015 - IPC H01P1/22 H03H11/24 

FIELD: electricity.

SUBSTANCE: UHF attenuator contains transmission lines at the input and output with identical wave resistance, six resistors, four field transistors with Schottky barrier, two sections of the transmission line with the length equal to a wavelength quarter in the transmission line, and the wave resistance exceeding the wave resistance of transmission lines at the input or at the output, two sources of DC control voltage.

EFFECT: decrease of real UHF loss and expansion of functionality due to increase of number of attenuation levels.
