POLARIZATION SWITCH Russian patent published in 1994 - IPC

FIELD: TV signal receiving equipment. SUBSTANCE: device has section of input cylindrical waveguide with quarter-wave dielectric transformer, connected in series with ferrite section with longitudinal magnetization coil, cut of rectangular waveguide with output dielectric waveguide and output rectangular waveguide. Size of wide wall of rectangular output waveguide is larger, than corresponding cuts of rectangular waveguide, and size of narrow wall of output rectangular output waveguide is less, than corresponding size of cut of rectangular waveguide. Length of output dielectric transformer excesses over length of cut of rectangular waveguide for value of (5-15)x10^-3·λ₂, where λ₂ is wavelength of output rectangular waveguide. EFFECT: improved efficiency. 4 dwg
