RESISTANCE TRANSFORMER Russian patent published in 2017 - IPC H01P5/02 

FIELD: radio engineering, communication.

SUBSTANCE: resistance transformer contains three cascaded sections of the quarter-wave line segments. Parallel to the three sections of the quarter-wave segments of the transmission line, one quarter-wave section is included, and one short-circuited quarter-wave section of the transmission line is connected parallel to the input.

EFFECT: reducing the relative non-uniformity of the group delay function in a given bandwidth with a given resistance transformation coefficient and a specified maximum standing wave ratio and expanding the bandwidth with less stringent requirements for the relative non-uniformity of the group delay function at a given maximum standing wave ratio.
