BALANCED MIXER Russian patent published in 1995 - IPC

FIELD: processing of information radio signals. SUBSTANCE: balanced mixer includes section of rectangular waveguide in which E plane dielectric backing is located. One side of it carries first section of short- circuited waveguide-slit line presenting input of signal from heterodyne and second section of short-circuited waveguide-slit line which is input of information signal. The other side of backing carries strip conductor which first end is manufactured in the form of open rectangular loop and is coupled to output of intermediate frequency through intermediate frequency filter. Second end of strip conductor is connected to first heteropolar electrodes of mixing diodes which second electrodes are connected correspondingly to strip chokes shorted to wide wall of section of rectangular waveguide. EFFECT: enhanced reliability of reception and processing of information radio signals. 2 dwg
