FIELD: radio engineering, radio communication, radiolocation, radio counter measures where multichannel SHF frequency selective systems are required. SUBSTANCE: frequency-selective SHF matrix has multichannel splitter, channel filters-multiplexers. In the capacity of channel filters there are used filters with comb amplitude-frequency characteristic (comb filters) on multifrequency resonators based on sections of long line short-circuited on butts, for instance, waveguide which transmission bands repeat in band F of matrix after frequency intervals and form m columns and n lines of matrix. Arrangement of transmission bands of comb filters of lines and columns is realized so that they overlap input band F differing from each other as a minimum by transmission band Δfo. Elements coupling columns and lines are brought out from corresponding short-circuits multiple of integral number of half-waves of transmission band common for intersection of line and column. EFFECT: increased number of selection channels and decreased transition losses. 4 dwg
