IMPEDANCE BUFFER WITH LOOPS Russian patent published in 2008 - IPC H01P1/18 

FIELD: electricity.

SUBSTANCE: in impedance buffer containing cascade connection of two transmission line with in-parallel at its right ends disconnected loops, transmission lines have different lines l₁ l₂ and equal wave resistance Z₁, loops have different lines l₃, l₄ and equal wave resistance Z₂, at that l₁<l₂, l₃=l₂/2, l₄=l₁/2, where R>1 - difference of consistent wave resistances.

EFFECT: reduction of discontinuity quantity in transformer structure of wave resistances at keeping of broadband response.
