WAVEGUIDE BALANCE MIXER Russian patent published in 1998 - IPC

FIELD: radio engineering; broad-band, extremely-high-frequency instrument superheterodyne receivers. SUBSTANCE: mixer is built up of differentially-orthogonally connected first and second rectangular-waveguide sections for signal and heterodyne, respectively; one of wide walls of first section mounts conducting plate attached to it with its one end, and other wide wall has slit shorted out on one end and connected with matching slit transformer installed in second section of rectangular waveguide. Opposite end of conducting plate is located on longitudinal axis of slit whose opposite edges are connected to two mixing diodes through some electrodes while other electrodes are connected to opposite surfaces of conducting plate. EFFECT: improved design. 2 cl, 1 dwg
