FIELD: microwave technology.

SUBSTANCE: invention relates to the microwave technology. The frequency-separating device contains a housing with input and output connectors, inside which there are rod filters tuned to different frequencies and consisting of resonators based on rods, short-circuited at one end and open at the other and arranged parallel to each other. The filters are linked to a common rod connected to the input connector, the terminal rods of the filters are connected to the output connectors. Each of the resonators has the possibility of adjustment by means of a fixed adjusting screw. The housing of the device is made together with the filter rods in the form of a milled metal plate covered on both sides with metal covers.
