FIELD: radio technology. ^ SUBSTANCE: invention relates to UHF radio technology and can be used in waveguide receive/transmit routes of radiotechnical systems for elimination of out-of-band and unwanted oscillations. The filter contains a rectangular waveguide, separated by a partition into two waveguides of half of the height, in each of which is placed an inductive diaphragm, formed by transverse partitions, and band absorbing load. Filtering is carried out in two parts by the method of cutting from the base metal in the first part of the filter, then inside the first part of the filter is carried out by a splitter, simultaneously with the splitter on both its sides is carried out by transverse partitions. ^ EFFECT: elimination of adverse and out-of-band oscillations close to the working band frequencies, increasing reliability while working at high levels of power, improving coordination and eliminating further losses for the base oscillation; technological effectiveness of the manufacture and assembly of the filter; reduction in the mass-size characteristics and production costs of the receive/transmit route of radiotechnical systems. ^ 2 cl, 3 dwg |
