FIELD: radio engineering, communication.
SUBSTANCE: double-balanced frequency converter has two balanced frequency converters, input, heterodyne and output circuits, a 180° phase section, three pairs of interfaced phase changers; the output of the input circuit is connected to inputs of the first pair of interfaced phase changers, the outputs of which are connected to corresponding signal inputs of the pair of balanced frequency converters, heterodyne inputs of which are connected to corresponding outputs of the second interfaced pair of phase changers; the output of one of the balanced frequency converters is connected to the input of one phase changer of the third pair of interfaced phase changers, the outputs of which are connected to the input of the output circuit; the output of the other balanced frequency converter is connected to the input of the 180° phase section, the output of which is connected to the input of the other phase changer of the third pair of interfaced phase changers.
EFFECT: high degree of suppressing sideband components in the high-frequency range.
