FIELD: physics.
SUBSTANCE: invention relates to superhigh-frequency equipment and is intended for frequency selection of signals. In cascade connection of narrow and wide sections of strip line wide central section is closed by means of a piece of strip line with narrow conductor in central part of strip structure on upper side of substrate, wherein the regular conductor located on the lower side of the substrate, which is located under the wide section, is closed to the body only at one end.
EFFECT: high selectivity and reduced size of a low-pass filter.
