FIELD: radio electronics, centimeter and decimeter range of receivers. SUBSTANCE: device has printed antenna in the form of phased array made of resonator half-wave radiators with series strip adder on metallized dielectric substrata, diode mixer, heterodyne and printed intermediate frequency filter. Salient feature of design of input device consists in fabrication of lateral breaks in strip conductor of adder between connection points of radiators where capacitors are placed and in insertion of additional sections of strip conductors in number equal to number of selective circuits of intermediate frequency filter. First ends of additional conductors are connected to metallization of substrate and second ends - to points of attachment of stress unit to edges of half-wave radiators. such structure is band-pass intermediate frequency filter. Point of stress unit on edge of resonator half-wave radiator most distant from mixer is output of device. EFFECT: provision for selectivity over image channel in technological structure of minimal dimensions. 1 cl |
