RANDOMLY POLARIZED MICROWAVE SIGNALS SUPERHET RECEIVER CONVERTER Russian patent published in 1994 - IPC

FIELD: radio location; radiometry. SUBSTANCE: device has polarization separator made on the base of section of round waveguide. Two planar structures of balance mixers are mounted along the axis of the waveguide in mutually perpendicular planes onto dielectric substrates. Signal input of the balance mixer is connected with heterodyne input of the other one. Rectangular waveguide of heterodyne generator is connected to output end of section of round waveguide through waveguide adapter. E-surface of rectangular waveguide forms angle of 45 deg. with planes of any planar structure of balance mixers. Smooth rotation mechanism is mounted in the plane of connection of section of round waveguide and waveguide adapter; this mechanism rotates one waveguide relatively the other one. EFFECT: improved efficiency. 2 cl, 1 dwg
